Hand-picked cruises, honest local detail and everything you need to plan a night among the limestone islands of Vietnam’s quieter bay.
Bai Tu Long Bay is the north-eastern half of the great karst seascape of Quang Ninh: hundreds of jungle-topped limestone towers rising from green water, just beyond the edge of Ha Long Bay. The scenery is every bit as dramatic. The difference is that most of the boats stay behind.
Here you kayak lagoons with fishermen rather than fifty other kayaks, row through the floating village of Vung Vieng, climb into Thien Canh Son cave and anchor for the night with barely a light on the horizon. This guide helps you choose the right cruise, get there from Hanoi, time it around the weather and add the beaches of Quan Lan and Co To.

Overnight cruise from €118 The most-booked overnight cruise that actually leaves the crowded Ha Long loop. You board at the international cruise port in Ha Long, sail east into Bai Tu Long, kayak and swim in the afternoon, eat a set dinner on board and wake up to karsts with almost nobody else around.
Luxury overnight cruise from €110 A small, well-run five-star boat that spends its time in Bai Tu Long rather than queuing at Ha Long’s famous stops. Cabins are comfortable, the food is a clear step up from mid-range boats and the 4.9 rating over hundreds of reviews is remarkably consistent.
Day cruise from €75 If you are already staying in Ha Long, this is the best half day you can spend on the water. It heads east away from the main channels into Bai Tu Long; most departures stop at a floating fishing village such as Vung Vieng (check the day’s itinerary on the booking page) and you are back by mid-afternoon.
Multi-day cruise from €259 The version to book if you can give the bay a proper amount of time. The middle day is spent entirely on the water — usually a day boat to the far side of Bai Tu Long for kayaking and a beach — while the day-trippers are still on the expressway.
Overnight cruise from €128 Swan Cruises has been running its off-the-beaten-path Bai Tu Long route for years, and it shows: the itinerary is built around Thien Canh Son cave and the quiet lagoons nearby rather than the Ha Long highlights everyone else visits.
Overnight cruise from €123 A good-value mid-range cruise that sticks to the quieter waters of Bai Tu Long, with a visit to Vung Vieng, a hands-on cooking class and a relaxed evening on deck. Solid reviews and a price that undercuts most boats on this route.
Day trip from €34 The classic Ha Long Bay day from Hanoi, and one of the most-reviewed tours in Vietnam. It covers the famous stops — Sung Sot cave, Luon cave and Ti Top island — with lunch on board and expressway transfers. Busy, but efficient and excellent value.
Luxury overnight cruise from €98 Not Bai Tu Long — this one heads south-west into Lan Ha Bay, the other quiet alternative to Ha Long. We include it because it is one of the best-reviewed five-star cruises in the region and remarkably good value for balcony cabins.

Floating villages and caves in Bai Tu Long, white-sand islands beyond it, and Ha Long Bay’s great sights on the way in.
Bai Tu Long Bay Ha Long’s quieter sister
The same drowned limestone landscape as Ha Long Bay, continuing north-east towards Van Don — but with a fraction of the boats. Hundreds of jungle-topped karsts, fishing villages, hidden caves and a national park, seen from the deck of an overnight cruise.
Bai Tu Long Bay Life on the water
A floating fishing village tucked into a sheltered lagoon of Bai Tu Long, where houses, fish pens and pearl rafts ride on barrels beneath the karsts. Most visitors arrive by cruise and explore by rowing boat, paddled by a villager, or by kayak.
Bai Tu Long Bay The big cave of Bai Tu Long
Usually described as the largest cave on the Bai Tu Long cruise route: a steep staircase up a karst island leads into a high chamber of stalactites, with views back over the bay from the entrance. The signature stop of most overnight cruises here.
The outer islands Beaches and an old trading port
The best-known inhabited island of the Van Don archipelago: long white-sand beaches such as Minh Chau, pine forest, a historic communal house and a slow village pace. Reached by ferry or speedboat from Van Don, it is where Vietnamese families go for a beach break.
The outer islands The far end of the bay
An island district out in the Gulf of Tonkin beyond the karsts, with clear water, rocky headlands and some of the finest beaches in the north. It takes a speedboat from Van Don to get there, which keeps it quiet outside Vietnamese summer holidays.
Ha Long & Lan Ha The famous neighbour
The UNESCO World Heritage bay that made this coastline famous: some 1,600 limestone islands, caves and lagoons off Ha Long city. Busier than Bai Tu Long, but its big caves and viewpoints are spectacular — and most Bai Tu Long cruises start here.
Overnight cruise ships, Ha Long city hotels, Tuan Chau island resorts and beach stays on Quan Lan — compared, with live rates.
A full resort on its own island (Reu island) just off Bai Chay, reached by the hotel’s boat. Private beach, big pools and bay views — the most “away from it all” stay in the city.
The first international resort on Quan Lan island: villas and rooms behind a long empty beach, with pools and a spa. The splurge that makes the island trip.
Swan Cruises’ off-the-beaten-path boat, which sails the quieter Bai Tu Long route with Thien Canh Son cave and Vung Vieng.
The quieter half of Vietnam’s great karst seascape is 2.5 hours from Hanoi. Compare overnight cruises, day trips and transfers and book in a couple of taps.
For most people, yes. The limestone scenery is the same; what you gain is peace — far fewer boats, quieter anchorages and kayaking without a traffic jam. You give up some of Ha Long’s headline caves, which many cruises visit on the way anyway. See our full comparison.
By road to Ha Long, where most cruises board — about 2.5 to 3 hours on the expressway. Nearly every cruise includes a shuttle from Hanoi’s Old Quarter. See our Hanoi to Bai Tu Long guide for every option.
Overnight, if you possibly can. A day trip from Hanoi spends around five hours on the road for four or five on the water; one night on board gives you sunset, sunrise and the quiet hours when the bay is at its best.
The best small boats fill up a few weeks ahead in October–November and around Vietnamese holidays. Most cruises on GetYourGuide offer free cancellation, so there is little risk in booking early.
Typhoon season runs roughly July to October. When a storm threatens, the port authority suspends sailings and cruises are cancelled or rescheduled. Book with free cancellation and keep a spare day. More on the weather.
