Halong Bay Travel Guide: Cruises, Costs and Things to Do

Hạ Long means “descending dragon”, and the name arrives with a story attached: a dragon sent to defend the coast is said to have spat jade and pearls into the sea, which hardened into the limestone towers standing there today. There are close to 2,000 of them, scattered across a corner of the Gulf of Tonkin in Quảng Ninh province, in Vietnam’s far north-east.

Fishing families lived permanently on this water for generations, in floating villages such as Cua Van, until the province resettled most of them ashore in 2014. On land, Quảng Ninh built its wealth on coal, and the mines above Hon Gai are still working. UNESCO listed the bay in 1994 and extended the property in 2023 to take in the Cat Ba archipelago next door, making it Vietnam’s first World Heritage site shared between two provinces.

The mainland today is a resort city of cable cars, a hilltop Ferris wheel and a purpose-built night market, while the water two kilometres out still looks close to what the legend describes. The distance between those two versions of the same place is what caught me out on my first visit. This guide covers when to go, how long to stay, what to see on the water and on land, and what the whole thing costs.

Is Halong Bay Worth Visiting?

Yes, with one condition attached: your choice of water and your choice of boat decide almost everything about how the trip feels. The seascape itself is not overstated — 1,133 islands sit inside the inscribed property, and tower karst on this scale exists in only a handful of places on earth — but Halong is also Vietnam’s most aggressively marketed sight, and the central cruise route is where most of the 500-plus licensed boats concentrate.

Halong Bay is great for:

  • Anyone who wants a night on the water, with a sunrise and a sunset you cannot get on a day tour
  • Kayakers, since paddling into Luon Cave puts you at water level in places no cruise boat reaches
  • Budget travellers willing to shift across to Lan Ha Bay and Cat Ba, where the same karst costs $20 to $50 less
  • Cave visitors, with four sizeable show caves reachable on a single ticketed route

The honest caveat: a one-day tour from Hanoi means roughly five hours on the road for about four on the water, and I would not book one in July or August, when squalls form fast over the gulf and sailings get cancelled at short notice. Pick the season and the format carefully and the rest of this guide falls into place.

Best Time to Visit Halong Bay

Late October to December is the strongest window, with dry air, calm water and the clearest visibility of the year across the karst. Mid-March to mid-April is the useful second choice. January and February are cool and drizzly, and February averages just 1.5 hours of sunshine a day, so the towers spend a lot of that period wrapped in haze.

Off-Season to AvoidJune–September31–3224–2628–2914–19/month

Peak Season (October–December)

Autumn into early winter brings dry, settled weather, highs sliding from 29°C in October to 22°C in December, and only five to ten wet days a month. Visibility is at its best, cancellations are rare, and the karst photographs sharply instead of disappearing into mist. No major festival falls in this window, so the draw is purely the weather, though December weekends fill with domestic visitors.

Shoulder Season (March–May)

Spring warms quickly, from 22°C in March to 30°C by May, with 11 to 14 rainy days a month and a lot of low cloud early on. Sea temperatures climb past 27°C by May, which is the first point in the year when swimming off Ti Top Island is actually pleasant, and boats are cheaper than in autumn. The Yen Tu Spring Festival opens on the tenth day of the first lunar month and runs for roughly three months, filling the mountain 50 km inland with pilgrims.

Off-Season to Avoid (June–September)

This is the monsoon, hot and heavy at 31°C to 32°C with humidity to match, and August alone averages 445 mm of rain across 19 wet days. Typhoons track through the Gulf of Tonkin from late May to early November, peaking between July and October, and the Halong Bay Management Board suspends departures whenever conditions turn. Vietnam’s National Day on 2 September brings a domestic surge, which is worth knowing if you were planning to travel that week regardless.

How Many Days to Spend in Halong Bay

Three days is the number that works. That covers a full day on the mainland around Bai Chay and Hon Gai, an overnight cruise taking in Sung Sot Cave and Ti Top Island, and a third morning either back through the caves or across to Cat Ba.

Cut it to a single day trip from Hanoi and you get roughly four hours on the water, no sunrise, no sunset, and a long bus ride bracketing both ends. A fourth or fifth day opens up Cat Ba National Park, the climbing scene at Lan Ha Bay, or the far quieter Bai Tu Long route where a fraction of the fleet operates. For an exact day-by-day plan, see the full Halong Bay itinerary below.

Halong Bay Itinerary for 3 Days

Three days here split cleanly between land and water rather than by the clock: one day on the mainland, one boarding and cruising the central bay, and one morning at sea before either heading back or crossing to Cat Ba. Day 1 stays in Halong City on both sides of the Bai Chay Bridge, Day 2 moves onto the water from Tuan Chau, and Day 3 offers a branch depending on how much time you have left.

Day 1 — Mainland Halong: Bai Chay and Hon Gai

Bai Chay Waterfront and Sun World

Start on the western side of the bridge, where most hotels sit. The Queen Cable Car climbs from Ocean Station to Ba Deo hill in two-storey cabins for 250,000 VND (~$9.50) return, and the ride out over the water is the cheapest wide view of the bay you will get without boarding anything. At the top, the Sun Wheel keeps turning until late, and the Japanese-styled gardens on Ba Deo fill the gap before lunch.

Lunch — Hong Hanh 3 at 50 Ha Long Street, a short walk back down towards the waterfront, where the chả mực comes with mantis shrimp and grilled squid.

Hon Gai Across the Bridge

Cross the Bai Chay Bridge by taxi and the tone changes within a kilometre. The Quang Ninh Museum on Tran Quoc Nghien Street is the obvious anchor, a black glass block on the seafront covering the province’s maritime history and its coal-mining century, open 8 am–12 pm and 1 pm–5 pm, so time your arrival around the lunch closure. From there it is a ten-minute walk to Hon Gai market and Long Tien Pagoda beneath the cliffs of Bai Tho Mountain.

Dinner — Bánh cuốn chả mực Gốc Bàng in Hon Gai, where steamed rice rolls arrive with squid cake cut into wedges at the table, then double back to the Halong Night Market on Hoang Quoc Viet Street for pearl yogurt.

Day 2 — Onto the Water: Boarding and the Central Bay

Tuan Chau Marina

Most overnight boats board at Tuan Chau International Marina between 11:30 am and 12 pm, with the bay route ticket built into the fare. Get there early rather than exactly on time, because the check-in lounge processes several hundred passengers at once and boats leave on the schedule the port authority sets, not yours.

Lunch — served on board as the boat clears the harbour, usually a set seafood spread; drinks are charged separately and plastic bottles are not permitted in the bay.

Sung Sot Cave and Ti Top Island

The afternoon covers the two headline stops on Route 2. Sung Sot, the Cave of Surprises, runs through two vast chambers on a stepped path of roughly 700 steps, and it is genuinely enormous rather than merely lit dramatically. Ti Top follows, where a staircase of around 400 steps ends at a viewpoint over the whole scattered fleet, and the small crescent beach below is the only spot in Halong proper where swimming is permitted.

Luon Cave by Kayak

Late afternoon usually means kayaks or a bamboo boat through the low arch at Luon Cave, which opens into a ring of cliffs enclosing still green water. Take the kayak rather than the rowed boat if you have the choice, since it lets you cross the lagoon at your own pace and get into the corners where the monkeys sit.

Dinner — on board at anchor, followed by squid fishing off the back deck with bamboo poles and lamps, which catches very little and is enjoyable anyway.

Day 3 — Sunrise, Caves and the Cat Ba Branch

Sunrise on the Bay

Cruises run tai chi on the sundeck around 6:30 am, and even if that holds no appeal, the hour before the fleet starts moving is the quietest the bay ever gets. Breakfast follows, then most boats visit one more cave — Thien Cung or Me Cung depending on the route — before turning back towards Tuan Chau to disembark around 11:30 am.

Lunch — a final meal on board during the return leg, or at the marina if your boat runs an early disembarkation.

Or: Cross to Cat Ba and Lan Ha Bay

With a spare day, skip the return transfer and take the ferry from Tuan Chau to Gia Luan on Cat Ba instead. The island puts you inside the quieter half of the same UNESCO property, with Cat Ba National Park for a half-day trek and Cannon Fort above the town for a sunset that looks straight down onto Lan Ha Bay.

Dinner — Cat Ba town waterfront if you crossed over, or back in Bai Chay if you returned to the mainland.

How to Get to Halong Bay

Almost everyone arrives by road from Hanoi, and the expressway has made that the fastest option by a wide margin.

By Air

Van Don International Airport (VDO) is the closest runway, roughly 50 km east of Halong City and about an hour away by road, but its schedule is thin and most weeks it serves only a handful of routes. Cat Bi International Airport (HPH) in Hai Phong sits around 75 km south and works well if you are heading straight for Cat Ba. In practice, the large majority of travellers land at Noi Bai International Airport (HAN) in Hanoi, 160 to 190 km away and about 2.5 to 3 hours by road, where Terminal 2 handles international arrivals and Terminal 1 covers domestic flights on Vietnam Airlines, VietJet Air and Bamboo Airways. Comparing fares on Aviasales before committing to a Hanoi arrival is worth the two minutes, since a Cat Bi routing occasionally works out cheaper and closer.

By Train

There is no useful passenger train to Halong. A rail line technically reaches Halong station, but scheduled services on it are effectively non-existent, and anyone telling you to catch a train from Hanoi to the bay is working from an old guidebook. The one rail option that does make sense is the Hanoi to Hai Phong line, a slow but genuinely pleasant two-and-a-half-hour ride, from where you can pick up a speedboat to Cat Ba.

By Bus

Road transfers leave Hanoi’s Old Quarter through the day and run 2.5 to 3 hours via the Hanoi–Hai Phong and Ha Long–Hai Phong expressways, the second of which opened in 2018 and cut roughly two hours off the old national road. Standard coaches start around 153,000 VND (~$5.80), while limousine vans with nine to eleven leather seats and door-to-door pickup run from about 274,000 VND (~$10) up to $23. Van Don Xanh, Hoang Phu, Phuc Xuyen and Cat Ba Express all cover the route, the last running combined bus and ferry tickets through to Cat Ba town. Booking through 12Go rather than at a hotel desk lets you compare departure times and seat classes side by side.

How to Get Around Halong Bay

Walking: Fine along the Bai Chay waterfront, where the promenade, the night market and most hotels sit within a few hundred metres of each other, and fine again inside Cat Ba town. Beyond that, forget it. Halong City is strung along roughly 20 km of coast road, and the gap between Bai Chay and Hon Gai involves crossing a long road bridge with no realistic pavement route, so a map that makes the city look compact is lying to you.

Taxi (Grab and Xanh SM): Both apps work across the mainland city, with Xanh SM running electric cars and bikes and generally undercutting Grab by a small margin. Fares are metered in-app, which removes the negotiation entirely, and a motorbike taxi costs roughly a third of a car for the same trip. This is the sensible default for the Bai Chay–Tuan Chau and Bai Chay–Hon Gai runs that make up most travellers’ movement.

Motorbike or Scooter Rental: Around 150,000 to 200,000 VND (~$6–8) per day, cheaper by the week, and legally you need an International Driving Permit with the A1 category endorsed. On the mainland it is unnecessary, since the coast road is fast and unpleasant. On Cat Ba it is the single best way to travel, putting the national park, Hospital Cave and the far beaches within an easy loop.

Ferries and Speedboats: The Tuan Chau to Gia Luan ferry crosses to Cat Ba in about 50 minutes for 80,000 VND on foot, or 100,000 VND with a motorbike. From Hai Phong, speedboats out of Ben Binh reach Cat Ba in around 45 minutes. There is also the Cat Hai–Phu Long cable car, which crosses in under fifteen minutes, runs roughly 9 am–3:45 pm with a midday break and longer weekend hours, and is quoted between 50,000 and 100,000 VND one way depending on season.

Public Bus: A coastal route runs the length of Halong City between Bai Chay and Hon Gai for a few thousand dong, and on Cat Ba the island bus reaches the national park gate for around 13,000 VND. A hop-on double-decker sightseeing bus also loops the mainland waterfront for about $4.50, which is more useful than it sounds given how spread out the city is.

One caveat worth taking seriously: street-hailed taxis around the marinas and the night market have a long-standing reputation for rigged meters and inflated fixed quotes. Order through Grab or Xanh SM instead and the problem disappears entirely.

Where to Stay in Halong Bay

Bai Chay

The main tourist area on the western side of the bridge, and the default answer for a first visit. Hotels run from cheap guesthouses on the back streets to the big waterfront chains, and the night market, Sun World and the beach are all within walking distance of each other. It is the only part of the mainland with a genuine cluster of hostel beds, and it suits anyone joining a cruise the following morning without wanting to commit to Tuan Chau. The trade-off is that it is entirely built for visitors, and prices reflect that.

Hon Gai

Cross the bridge and you land in the working half of the city, where the markets, the museum and the best squid cake are, and where almost no international travellers stay. Accommodation is mostly small local hotels rather than hostels, and it is noticeably cheaper for the same standard of room. It suits longer stays and anyone who would rather eat where locals eat than where the tour buses stop. I would check how far your room actually sits from the waterfront before booking, since Hon Gai sprawls inland and the interesting part is a narrow strip along the coast.

Tuan Chau Island

A man-made island connected by causeway, home to Tuan Chau International Marina where most overnight cruises depart. It is dominated by resorts and villa complexes, with essentially no hostel scene and very little to do in the evening once you leave your hotel. Its one real argument is logistical: if your boat boards at 11:30 am and you would rather not gamble on cross-city traffic, one night here removes the risk. Otherwise it is a departure point rather than a base.

Cat Ba Island

The backpacker centre of the whole region, and the best-value bed in this guide by a clear margin. Cat Ba town has a dense strip of hostels and small hotels along the harbour front, a real traveller scene, dive and climbing operators, and direct access to Lan Ha Bay and the national park. It works as a base for several days rather than a stopover, and it is where I would send anyone travelling on a budget who wants more than a single night on the water.

On the Bay

Worth naming as its own option, because for many visitors the cruise cabin is the accommodation. A two-day, one-night boat replaces a hotel night entirely and buys you the sunrise, the quiet hours after the day fleet leaves, and the sections of the bay that day tours never reach. Bai Tu Long Bay, by contrast, has no land-based accommodation to speak of and is visited by boat only.

Sung Sot Cave

The largest show cave in the bay sits on Bo Hon Island, roughly 25 metres above the water, and is the single stop that appears on almost every Route 2 itinerary. French surveyors mapped it in 1901 and gave it the name Grotte des Surprises; Vietnamese guides translate it as the Cave of Surprises, which is close enough. It opened to visitors in 1993 and covers around 10,000 square metres across two connected chambers, the second considerably larger than the first.

Getting inside means climbing roughly 700 steps in humid air, and the first chamber gives no warning of the second, which opens out to the height of a cathedral with a floodlit path curling through it. Boats arrive in waves, so the difference between a 9 am visit and a midday one is substantial.

  • Area: On the Bay
  • Entry Fee: Included in the Route 2 ticket, from 290,000 VND (~$11)
  • Opening Timings: 6:30 am–6:30 pm, in line with bay visiting hours
  • How to Get There: Reached only by cruise boat from Tuan Chau or Halong International Cruise Port
  • Duration: 45 minutes

Ti Top Island

A small island with a crescent of imported sand, named after Gherman Titov, the Soviet cosmonaut who visited the bay with Ho Chi Minh in 1962 and had the island renamed in his honour on the spot. It has been the bay’s designated swimming stop ever since, and it is the only place inside Halong Bay proper where getting into the water is officially permitted.

The staircase to the summit is around 400 steps and unshaded, which sounds worse than it is until August. From the top you see exactly the view every photograph of Halong uses, plus the sobering reality of how many boats share the anchorage with you.

  • Area: On the Bay
  • Entry Fee: Included in the Route 2 ticket
  • Opening Timings: 6:30 am–6:30 pm
  • How to Get There: Standard afternoon stop on Route 2 day cruises and overnight itineraries
  • Duration: 1 hour

Luon Cave

Less a cave than a tunnel, this low arch through the base of Bo Hon Island opens into a circular lagoon ringed by cliffs, closed off from the open bay on every side. Motorised boats are banned inside, which is exactly why it stays quiet, and access is by kayak or by traditional bamboo rowing boat with a local oarswoman.

Clearance under the arch drops to a couple of metres at high tide and you duck to get through. Inside, the water goes glassy, macaques work the lower rocks, and the noise of the fleet cuts out completely. This was the part of the bay I would go back for.

  • Area: On the Bay
  • Entry Fee: Covered by the Route 2 ticket; kayak or bamboo boat hire adds around 60,000 VND (~$2.30)
  • Opening Timings: 6:30 am–6:30 pm
  • How to Get There: Kayak launch point on Route 2 cruises, usually late afternoon
  • Duration: 45 minutes

Thien Cung Cave

Thien Cung, the Heavenly Palace, sits high on Dau Go Island at the northern end of the bay and anchors Route 1 alongside its neighbour. The name comes from a legend in which the Dragon King’s wedding was held inside, and Vietnamese guides tell the story with the stalagmites cast as guests. It was opened to the public in the early 1990s and remains the more theatrically lit of the two caves on this island.

The chambers are tighter than Sung Sot’s and the coloured lighting is heavy-handed, but the density of formations is remarkable and the walk through is short. Pair it with Dau Go, five minutes away on the same island, rather than treating either as a separate outing.

  • Area: On the Bay
  • Entry Fee: Included in the Route 1 ticket, from 290,000 VND (~$11)
  • Opening Timings: 6:30 am–6:30 pm
  • How to Get There: Route 1 cruises from Tuan Chau Marina; the shortest cruise route from the mainland
  • Duration: 30 minutes

Dau Go Cave

The name means Wooden Stakes Cave, and it refers to one of the better stories in Vietnamese history: the ironwood stakes that Tran Hung Dao’s forces are said to have stored here before driving them into the bed of the Bach Dang River to wreck the Mongol fleet in 1288. French visitors called it the Grotte des Merveilles, and their nineteenth-century graffiti is still visible near the entrance.

Three chambers run back into the rock, drier and less aggressively lit than Thien Cung, with daylight reaching the first one through a wide mouth. It gets a fraction of the traffic of the caves on Route 2.

  • Area: On the Bay
  • Entry Fee: Included in the Route 1 ticket
  • Opening Timings: 6:30 am–6:30 pm
  • How to Get There: Same island as Thien Cung, a short walk between the two
  • Duration: 30 minutes

Trong Mai Islet

Two limestone stacks leaning towards each other in shallow water off Dinh Huong, known in English as the Fighting Cocks or the Kissing Rocks depending on who is guiding you. The pair has been used as the visual shorthand for Halong Bay for decades, appearing on tourism logos, postcards and roughly every brochure printed in Quang Ninh.

You do not land here; boats slow and circle while everyone photographs the same silhouette. Worth knowing that the base of the rocks has eroded noticeably and the authorities now monitor them for collapse risk, which lends the stop a certain urgency.

  • Area: On the Bay
  • Entry Fee: Included in the Route 1 ticket
  • Opening Timings: Viewed from the water during daylight sailings
  • How to Get There: Passed on Route 1 itineraries; no landing
  • Duration: 15 minutes

Cua Van Floating Village

Once the largest of the bay’s floating settlements, Cua Van housed several hundred people in painted wooden houses lashed to pontoons, with a floating school and a community centre. In 2014 the province resettled most residents on the mainland, and what remains functions as a cultural centre and a working anchorage rather than a full village. Families still work the water here, and some have returned seasonally.

Visits arrive by rowed sampan rather than cruise boat, which keeps the noise down. The Floating Cultural Centre documents what daily life looked like, and it is the only stop on the bay that engages with the people who lived on it.

  • Area: On the Bay
  • Entry Fee: Included in the Route 3 ticket, from 240,000 VND (~$9)
  • Opening Timings: 6:30 am–6:30 pm
  • How to Get There: Route 3 cruises only, a smaller share of the fleet
  • Duration: 1 hour

Vung Vieng Fishing Village

A small floating community in Bai Tu Long Bay, reached by rowed sampan from the mother boat and still partly inhabited by families who fish and farm pearls in the sheltered water. It is the quieter counterpart to Cua Van, with a fraction of the visitor numbers and no coach-tour rhythm to it.

The circuit takes in the pearl farm, where the seeding and harvesting process is explained without much of a sales push, and passes through a natural rock arch into an enclosed pool. Women from the village row the boats, which is worth a tip beyond whatever the cruise includes.

  • Area: Bai Tu Long Bay
  • Entry Fee: Included in the Route 4 ticket, from 240,000 VND (~$9)
  • Opening Timings: 6:30 am–6:30 pm
  • How to Get There: Rowed sampan transfer from Route 4 cruise boats
  • Duration: 1 hour

Cat Ba National Park

Established in 1986 and covering roughly half the island, the park is the last refuge of the Cat Ba langur, a golden-headed primate that exists nowhere else on earth and numbers somewhere around 60 to 70 individuals. That makes it one of the most endangered primates anywhere, and the reason conservation restrictions here are tighter than elsewhere in the bay.

Four marked trails run from the gate, from a short summit climb to a long route ending at Viet Hai village, where a boat can carry you back to town instead of retracing the path. Start early for the long walk; the park closes at 5 pm and the trail is slow after rain.

  • Area: Cat Ba Island / Lan Ha Bay
  • Entry Fee: 60,000–80,000 VND (~$2.30–3), plus 5,000 VND motorbike parking
  • Opening Timings: Daily until 5 pm; enter by 8 am for the Viet Hai route
  • How to Get There: 30 minutes by scooter or island bus from Cat Ba town
  • Duration: Half day

Trung Trang Cave

Roughly 300 metres of passage cutting straight through a limestone hill on the main island road, inside the national park boundary and covered by the same ticket. Hundreds of stalactites line the route, and the cave supports a permanent population of bats, insects and cave-adapted reptiles living in the dark sections. Islanders used it as a shelter during the bombing campaigns of the 1960s and 70s, which is why the floor was levelled long before tourism arrived.

You enter one side and come out the other rather than doubling back, and the lit path is the one to stay on. It runs several degrees cooler than outside, which makes it a sensible midday stop on a hot island loop.

  • Area: Cat Ba Island / Lan Ha Bay
  • Entry Fee: Included in the Cat Ba National Park ticket, or 40,000 VND (~$1.50) bought separately
  • Opening Timings: Daylight hours, in line with national park access
  • How to Get There: On the main road north of Cat Ba town, a few minutes past Hospital Cave
  • Duration: 30–45 minutes

Hospital Cave

A three-storey field hospital built inside a natural cave between 1963 and 1965 with Chinese assistance, engineered so the rock above would absorb anything dropped on it. It stayed in service until 1975, running seventeen rooms across roughly 2,000 square metres — an operating theatre, wards, a kitchen, a cinema room and a chamber set aside for closed meetings. It sits in Hai Son village, 13 km north of Cat Ba town on the road towards the national park.

Two of the three levels are open, the top one shut after landslide risk was identified, and the rooms are laid out with mannequins and period equipment. The ticket includes a guide, which matters here — the space explains very little on its own.

  • Area: Cat Ba Island / Lan Ha Bay
  • Entry Fee: 40,000–50,000 VND (~$1.50–2), guide included
  • Opening Timings: Daylight hours; no reliably published closing time, so avoid a late-afternoon arrival
  • How to Get There: 13 km north of Cat Ba town by scooter, taxi or the island shuttle bus
  • Duration: 45 minutes

Cannon Fort

An artillery position on the ridge directly above Cat Ba town, signposted as High Point 177 after its height in metres, and dug in by Japanese forces in 1942. The French took it over during the First Indochina War and North Vietnamese gunners held it during the American war, making it one of the few sites in the country used in three separate conflicts. Two restored coastal guns still sit in their emplacements, connected by tunnels, trenches and observation bunkers cut into the rock.

The guns are the pretext; the view is the reason to climb. It takes in the town, the harbour and the full scatter of Lan Ha Bay beyond. There’s a small café at the top, and late afternoon is when the light does the work — though I would allow time for the haze to lift rather than assume it will.

  • Area: Cat Ba Island / Lan Ha Bay
  • Entry Fee: 40,000–50,000 VND (~$1.50–2); collection at the gate is informal and a printed ticket is not always issued
  • Opening Timings: 6:30 am–6 pm
  • How to Get There: A short but steep ride or walk up from Cat Ba town; no bus route, parking at the gate
  • Duration: 1 hour

Sun World Ha Long

The mainland’s purpose-built attraction complex, opened in stages from 2016, centred on the Queen Cable Car linking Ocean Station in Bai Chay to Ba Deo hill. The cabins carry two decks and hold two Guinness records, for the highest passenger capacity in a cable car cabin and for the tallest cable car tower. At the top sit the Sun Wheel, a Japanese-styled garden and a wax museum.

Because Ba Deo is already elevated, the view from the wheel clears far more than the wheel’s own height suggests, taking in the bridge, the harbour and the first line of islands. It is the cheapest wide view of the bay available without boarding a boat.

  • Area: Bai Chay
  • Entry Fee: 250,000 VND (~$9.50) return for the Queen Cable Car; Dragon Park from 95,000 VND (~$3.60)
  • Opening Timings: Daily, with hours shifting seasonally and evening operation in summer
  • How to Get There: On Ha Long Street in Bai Chay, opposite the main hotel strip
  • Duration: 2–3 hours

Quang Ninh Museum

Opened in 2013 and designed by the Spanish architect Salvador Pérez Arroyo, the museum is a black glass cube on the Hon Gai seafront, built to mirror the sea and sky. Its three floors move upward through the province’s story: marine ecology on the ground floor, history above it, and the coal industry that built modern Quang Ninh at the top.

A whale skeleton dominates the entrance hall, and the mining floor recreates a section of pit tunnel that lands harder than any display case. It is also the obvious wet-weather option in a destination where the main attraction is entirely outdoors.

  • Area: Hon Gai
  • Entry Fee: 40,000 VND (~$1.60) adults; 20,000 VND students; 10,000 VND children
  • Opening Timings: 8 am–12 pm and 1 pm–5 pm; closed for lunch, and closed on the last Monday of the month
  • How to Get There: Tran Quoc Nghien Street, about 7 km from Bai Chay across the bridge
  • Duration: 1.5 hours

The overnight boat is what most people mean when they say they are going to Halong Bay. Vessels board at Tuan Chau International Marina or Halong International Cruise Port around midday and return roughly twenty-four hours later, following one of four numbered routes that determine which caves, islands and villages appear on the itinerary. Two days and one night is the standard format, while three-day versions add a full middle day aboard a smaller day boat that reaches water the overnight fleet does not.

What you are paying for is the stretch after the day fleet goes home, when the anchorage empties and the engine noise stops altogether. Cooking classes, squid fishing off the stern and sunrise tai chi fill the hours around it, though none of those are the reason to be out there.

  • Experiences: Iconic, Sunset / Sunrise, Solo / Social
  • Price Range: $110–$260 per person
  • Duration: 2 days, 1 night, or 3 days, 2 nights

Day Cruise from Hanoi

The single most-booked activity in the destination, and the compromise most travellers on a fixed Vietnam route end up making. Pickup from the Old Quarter runs between 7:30 am and 8 am, the expressway takes about three hours each way, and boarding happens around midday for a Route 2 sailing that covers Sung Sot Cave and Ti Top Island before turning back. One operator’s listing has passed 70,000 bookings; another carries close to 13,000 reviews.

Twelve hours door to door yields roughly four on the water, which is the honest arithmetic nobody puts in the product description. Lunch is a seafood buffet served while cruising, and kayaking is usually offered as a short paid add-on.

  • Experiences: Iconic
  • Price Range: $30–$50 per person
  • Duration: 8–12 hours
  • Book via: Klook / GetYourGuide

Kayaking in Halong Bay

Quang Ninh province tightened the rules here some years ago, and paddling is now permitted in eight designated zones rather than anywhere a boat happens to stop. Ba Hang, Luon Cave and the Tung Sau area are the ones that appear most often on cruise itineraries. Where motorised craft are banned outright, a kayak or a rowed bamboo boat with a local oarswoman is the only way in, which is exactly what keeps those pockets quiet.

Sitting at water level changes the proportions completely, and the arches that look like nothing from a top deck turn out to be tunnels you can paddle through. It is also the one hour on a cruise where nobody is telling you where to be.

  • Experiences: Adventure / Outdoor, Under-the-Radar
  • Price Range: $2–$10 per person, often bundled into the cruise fare
  • Duration: 45 minutes–1 hour
  • Book via: Klook / GetYourGuide

Lan Ha Bay Day Cruise from Cat Ba

Boats leave Beo Pier and Got Harbour on Cat Ba for seven or eight hours in the southern half of the same UNESCO property, typically covering the Dark and Bright Cave, the Ao Ech area, Ba Trai Dao and a swim stop or two. Group sizes are smaller than on the Halong side, the licensed fleet is a fraction of the size, and fares undercut the Quang Ninh equivalents at the same standard by a wide margin.

Swimming is allowed across the bay rather than at one sanctioned beach, so most boats simply cut the engine somewhere quiet and let people jump off the deck. Floating fish farms replace the old floating villages, still worked daily.

  • Experiences: Under-the-Radar, Adventure / Outdoor
  • Price Range: $30–$50 per person
  • Duration: 7–8 hours
  • Book via: Klook / GetYourGuide

Seaplane Flight over the Bay

Vietnam offers scenic seaplane flights in only two places, and Halong is one of them. A twelve-seat floatplane lifts off from the water at Tuan Chau for a twenty-five-minute loop over the karst field, and the same aircraft also runs as a direct transfer from Hanoi in roughly forty-five minutes, at several times the price of the road.

From 150 metres up the islands stop reading as a horizon and start reading as a field, scattered across the water in a pattern no boat deck can show you. Take-off and landing on the water are half the entertainment.

  • Experiences: Splurge / Luxury, Iconic
  • Price Range: From $95 per person for the scenic flight; transfer flights from Hanoi cost considerably more
  • Duration: 25 minutes
  • Book via: GetYourGuide

Rock Climbing on Cat Ba

Cat Ba is the centre of Vietnamese rock climbing, and the limestone that makes the bay photogenic makes it climbable too. Bolted routes sit inland at Butterfly Valley, but the draw is deep-water soloing: boats drop climbers at the base of a cliff to climb ropeless above the sea, with the water as the only landing. Operators run trips out of Cat Ba town daily through the warmer half of the year.

Falling is part of the format rather than a failure, and beginner lines start low enough that the drop is measured in metres. Sea temperatures pass 27°C by May, which is when the falls stop being bracing.

  • Experiences: Adventure / Outdoor
  • Price Range: $60–$90 per person
  • Duration: Full day

What to Eat in Halong Bay

Quang Ninh eats differently from Hanoi three hours down the road, and almost all of it comes out of the water.

Chả Mực

Halong’s defining dish is a squid cake, hand-pounded rather than blended so the texture stays springy, then fried until the outside blisters. Locals will tell you it only counts if the squid was caught in Halong waters, and the pounding is done by hand with a wooden mallet because a machine turns it to paste.

Where to eat it: Chả Mực Quang Phong near Cai Dam Market in Bai Chay, which has been frying to order for decades and sells out by mid-afternoon, so treat it as a late-morning stop rather than an evening one.

Bánh Cuốn Chả Mực

The local pairing that exists almost nowhere else: paper-thin steamed rice rolls filled with pork and wood-ear mushroom, served with wedges of the squid cake on the side rather than the usual fried shallots and pork sausage.

Where to eat it: Bánh Cuốn Chả Mực Gốc Bàng in Hon Gai, on the working side of the bridge, where the rolls are steamed on a cloth in front of you (go for breakfast, when the batter is at its freshest and the queue moves quickly).

Ngán

A mud clam found in the brackish flats around Quang Ninh, sold live and prepared several ways — grilled over coals, dropped into rice porridge, or, most famously, cracked open with the liquid stirred straight into rice wine. It is an acquired taste that locals treat as a regional point of pride.

Where to eat it: Hong Hanh 3 at 50 Ha Long Street in Bai Chay, a long-running seafood house where the tanks by the door decide your order (dinner is the natural slot, when the grill is running properly).

Sữa Chua Trân Châu

Halong’s contribution to the yogurt-and-tapioca genre, thicker and more sour than the sweetened versions found further south, served cold with chewy pearls and eaten with a spoon. It became a genuine local obsession before the rest of Vietnam caught up.

Where to eat it: Sữa Chua Trân Châu Cô Nghi at 10 Văn Lang in Hon Gai, a small shop that stays busy from mid-afternoon onwards and is the name locals give you first.

Food Safety in Halong Bay

  • Buy seafood by pointing at the live tank and agreeing a price per kilo before anything is cooked, not after
  • At seafood markets, carry a sealed 550 ml water bottle — putting it on the scale is the local way of checking whether the scale is honest
  • Chả mực should arrive hot from the fryer; anything sitting warm at a market stall has been there a while
  • Tap water is not drinkable, and plastic bottles are restricted on the bay, so bring a refillable bottle and fill from your boat’s dispenser
  • Stalls in Hon Gai are largely cash-only, while ATMs cluster along the Bai Chay hotel strip

Where to Shop in Halong Bay?

Shopping here splits between the tourist-facing strip in Bai Chay and the markets where the city actually buys its dinner.

Halong Night Market

A covered market on Hoang Quoc Viet Street in Bai Chay that runs from late afternoon until around 10 pm, built specifically for visitors and priced accordingly. It sits close enough to the main hotels that most people wander in on their first evening without planning to.

  • Good for: Evening browsers and last-night souvenir buyers
  • What to buy: Freshwater and cultured pearls, dried squid and seafood, carved anthracite coal ornaments, conical hats

Cai Dam Market

The general market for the Bai Chay side, selling household goods, clothing and fresh produce to residents rather than visitors, with the city’s best-known squid cake stalls clustered around its edges. Prices are fixed on most things and the range is broader than anything on the tourist strip.

  • Good for: Self-caterers and anyone shopping for the ferry
  • What to buy: Dried seafood by weight, local snacks, cheap beach kit

Hon Gai Market

Across the bridge on the working side of the city, this is the wet market where the fishing boats’ catch lands each morning. It is loud, wet underfoot and entirely unbothered by tourism, which is exactly the appeal for anyone who wants to see how the city eats.

  • Good for: Early risers and food-focused travellers
  • What to buy: Live shellfish, sá sùng (sandworm) sold dried, fresh noodles

Haggling is expected at the night market and nowhere else — start around half the opening price and settle somewhere near two-thirds. At Cai Dam and Hon Gai, the price you are quoted is generally the price locals pay.

Day Trips from Halong Bay

Quang Ninh is large, and once you have finished with the water there are mountains, islands and a major port city all within a morning’s drive.

Yen Tu Mountain

The birthplace of Vietnamese Truc Lam Zen Buddhism, founded when a thirteenth-century emperor abdicated to become a monk here, and inscribed on the UNESCO World Heritage list in July 2025 as part of the Yen Tu–Vinh Nghiem–Con Son, Kiep Bac complex. It remains an active pilgrimage site rather than a museum piece.

  • How Far: About 50 km west, roughly 1.5 hours by road
  • Getting There: Private car or Grab is simplest; organised day tours run from both Halong and Hanoi and can be compared on Klook or GetYourGuide; public buses reach Uong Bi but leave you a taxi ride short
  • What to Do: Ride the two cable car stages, walk the stone path to Hoa Yen Pagoda, and continue to the bronze Dong Pagoda at 1,068 metres

Yen Tu rewards more attention than a single visit allows — our Places to Visit in Yen Tu guide covers the whole complex.

Quan Lan Island

An outer island in the Van Don archipelago that was a working international trading port in the twelfth century and is now known for long, empty beaches and shifting sand dunes. It sees a fraction of Cat Ba’s visitors and almost no foreign ones.

  • How Far: About 60 km to Cai Rong port, then 45–60 minutes by ferry
  • Getting There: Bus or car to Cai Rong, then the passenger ferry; sailings are weather-dependent and thin out in winter
  • What to Do: Swim at Minh Chau and Son Hao beaches, visit the 18th-century Quan Lan communal house, cycle the island road end to end. Ferry timings make this a stretch as a day trip — one night on the island is the honest recommendation

Planning to stay over? Our Places to Visit in Quan Lan guide has the full rundown.

Hai Phong

Vietnam’s third-largest city and its most important northern port, with a compact French colonial core that most travellers pass straight through on the way to Cat Ba without ever stopping. It is also one of the strongest food cities in the north.

  • How Far: About 75 km south, around 1.5 hours on the expressway
  • Getting There: Limousine vans and coaches run frequently and can be booked through 12Go; a private car costs more but drops you in the centre
  • What to Do: Eat bánh đa cua at a street stall, walk the colonial quarter around the Opera House, visit Du Hang Pagoda

There is far more to the city than a lunch stop — see our Hai Phong Travel Guide for the full picture.

Ninh Binh

Limestone karst that rises from flooded rice fields instead of the sea, which is why it gets called the inland version of the bay. The scenery is genuinely comparable and the boats are rowed by hand, often with the oarswoman’s feet.

  • How Far: About 180 km south-west, roughly 3 hours by road
  • Getting There: Direct transfers and tours run from Halong, bookable through 12Go or GetYourGuide; there is no useful train connection between the two
  • What to Do: Take the Trang An boat route through the water caves, climb the steps at Mua Cave, cycle through Tam Coc. At three hours each way this is a long day — most travellers give it two nights

Our Ninh Binh Travel Guide covers the routes in detail, and Best Hostels in Ninh Binh has the accommodation sorted.

Halong Bay Travel Budget

Halong Bay runs from roughly $25 a day as a backpacker to $180 and upwards at the luxury end, with the cruise you choose accounting for most of the difference.

Travel StyleAvg. Daily CostAccommodationFood & DrinkTransportActivities
Budget / Backpacker$25–45$6–12 (Cat Ba hostel dorm)$5–12 (street chả mực, market bowls)$3–8 (shared limousine seat, island bus)$15–35 (Lan Ha day cruise)
Mid-Range$60–120$25–50 (Bai Chay hotel, sea view)$15–30 (seafood restaurant dinner)$10–20 (limousine van from Hanoi)$35–60 (Halong day cruise, cable car)
Luxury$180–400+$90–200 (balcony cabin or resort suite)$40–80 (hotel dining, onboard drinks)$25–95 (private car or seaplane transfer)$95–260 (seaplane flight, 3-day cruise)
  • Accommodation: A dorm bed on Cat Ba costs a third of a comparable room in Bai Chay, and roughly a tenth of a balcony cabin on the water
  • Food & Drink: Eating on the Hon Gai side rather than the Bai Chay strip cuts a seafood dinner close to half
  • Food & Drink: Cruise fares cover meals but almost never cover drinks, which is where onboard bills quietly build
  • Transport: The shared limousine from Hanoi is the single best value in the whole budget, at around a tenth of a private car
  • Activities: Bay route tickets are bundled into cruise fares, so the sticker price of a cruise is closer to the true cost than it first appears

Halong Bay Travel Tips

A few practical things worth sorting before you arrive, most of them country-level rather than specific to the bay.

Visa & Entry — Vietnam’s e-visa covers up to 90 days at $25 for single entry and $50 for multiple, applied for at evisa.gov.vn with processing in three to five working days. iVisa handles the paperwork for a fee if you would rather not deal with the government portal, and our Vietnam Visa for Indians guide covers the process in detail.

Border Crossings — Quang Ninh shares a land border with China, with the main crossing at Mong Cai around 180 km north-east of Halong. Most Vietnamese land borders do not issue visas on arrival, so sort your e-visa before travelling overland.

SIM Cards — Viettel has the best coverage across the islands, with Vinaphone and Mobifone close behind. Dealer counters sit past customs at Noi Bai and Van Don, or buy a SIM or eSIM in advance through Klook or Airalo and land connected.

Hostels — Our Best Hostels in Halong Bay guide covers specific picks across Bai Chay and Cat Ba. For live pricing and cancellation terms, compare Booking.com against Agoda, which often differ on the same property.

Transportation — Grab and Xanh SM both operate in Halong City and remove any argument about fares. For intercity buses and the Cat Ba ferry combinations, 12Go lets you compare operators and departure times in one place.

Travel Insurance — World Nomads can be bought before you leave or once you are already travelling, with claims handled online from anywhere. Worth having anywhere involving boats, ferries and cave staircases.

Currency — The Vietnamese dong runs at roughly 26,000 to the US dollar. Watch the 20,000 and 500,000 notes, which are both blue polymer and near-identical at a glance — the classic way to overpay by a factor of twenty-five.

Flights — Compare fares into Noi Bai, Cat Bi and Van Don before committing, since a Hai Phong arrival is sometimes cheaper and closer. Aviasales is the quickest way to see all three side by side.

Electrical Plugs — Vietnam runs on 220V at 50 Hz with type A, C and F sockets; travellers from the UK, US or Australia will need an adapter, though many hotels now fit universal sockets.

Health & Water — Tap water is not safe to drink anywhere in the region, including on boats. Emergency numbers are 113 for police, 114 for fire and 115 for an ambulance.

Frequently Asked Questions

Is Halong Bay worth visiting?

Yes, provided you choose carefully. The karst seascape is genuinely rare, but the central route carries most of the fleet, so the experience depends heavily on which bay you pick and whether you stay overnight rather than day-tripping from Hanoi.

How many days do you need in Halong Bay?

Three days works best: one on the mainland around Bai Chay and Hon Gai, one boarding an overnight cruise, and a third either at sea or crossing to Cat Ba. Two days covers the classic cruise alone.

Is Halong Bay expensive to visit?

It runs from about $25 a day as a backpacker to $180 and up at the luxury end. The cruise is the swing factor — day trips start near $30, while balcony cabins on overnight boats reach $260 for a three-day sailing.

Are Halong Bay cruises safe?

Regulations tightened significantly after the July 2025 capsizing that killed 39 people. Every vessel now needs AIS, VHF and GPS tracking monitored around the clock, wooden hulls must be replaced with steel by 2030, and the management board suspends departures when weather turns.

What happens if bad weather cancels my cruise?

Sailings are permit-gated daily, and the board grounds the fleet outright during storm warnings. Most operators reschedule or refund, but policies vary — book through a platform with free cancellation and leave a spare day in your itinerary during typhoon season.

Is Halong Bay one of the Seven Wonders of the World?

Not officially. It won a place in the New7Wonders of Nature poll in 2011, which was a public online vote run by a private foundation rather than a UNESCO or academic designation. Its actual credential is World Heritage status, held since 1994 and extended in 2023.

Can you swim in Halong Bay?

Only at designated spots. Within Halong Bay proper, Ti Top Island is the sanctioned swimming beach. Lan Ha Bay is the opposite — swimming is permitted across the bay, which is why boats there simply cut the engine and let people jump in.

Is Halong Bay suitable for travellers with limited mobility?

Not easily. Sung Sot Cave involves roughly 700 steps, Ti Top around 400, and almost every cruise vessel has stairways rather than lifts, with transfers between boats made by tender. A private day boat avoids most of this.
