Ha Long, Lan Ha or Bai Tu Long? Day cruise or overnight? A practical guide to choosing the right Vietnam bay cruise, from cabins and routes to what is really included.
Short answer: Choose Ha Long Bay for the famous caves and classic views, Lan Ha Bay for fewer boats, better kayaking and swimming, and Bai Tu Long Bay for the quietest experience. For most European travellers we recommend one night on a boutique boat in Lan Ha Bay.
Almost every Vietnam itinerary includes "Ha Long Bay", but very few travellers realise that there are three neighbouring bays to choose from, and that the cruise you pick shapes one of the most memorable nights of your holiday. Our operations team in Vietnam inspects these boats every season, so here is our honest comparison.
The three bays in one paragraph each
Ha Long Bay
The UNESCO-listed original, with almost 2,000 limestone islands and islets rising from emerald water. It has the most famous sights — Sung Sot (Surprise) Cave, Ti Top island and the Fighting Cocks rocks — and the largest number of boats. In high season the main routes can feel busy around midday.
Lan Ha Bay
South of Ha Long, around Cat Ba island, Lan Ha shares the same karst scenery but has fewer boats, small white-sand beaches and calmer lagoons. It is the best choice for kayaking and swimming, and our favourite for couples and families.
Bai Tu Long Bay
North-east of Ha Long, Bai Tu Long is the quietest of the three, with fishing villages and wide open views. Fewer boats operate here, which is exactly the point.
Comparison table
| Ha Long Bay | Lan Ha Bay | Bai Tu Long Bay | |
|---|---|---|---|
| Scenery | Iconic, famous caves | Equally dramatic, small beaches | Open, wild, fishing villages |
| Boats on the water | Many | Moderate | Few |
| Kayaking & swimming | Good | Excellent | Good |
| Best for | First-timers, classic photos | Couples, families, active travellers | Repeat visitors, quiet seekers |
| Transfer from Hanoi | About 2.5 hours | About 2.5–3 hours | About 3 hours |
Day cruise or overnight?
A day cruise works if you are short on time: about four hours on the water, lunch and a cave or kayak stop. But you spend five hours on the road for four hours in the bay. An overnight cruise gives you sunset drinks on deck, a quiet evening anchored among the islands and — the highlight for most guests — sunrise with almost no other boats around. For European travellers coming such a long way, we always recommend at least one night.
What a good overnight cruise includes
- Shared or private transfer from Hanoi.
- Cabin with private bathroom and, on better boats, a private balcony.
- All meals on board — usually seafood-focused, with vegetarian options on request.
- Kayaking or bamboo-boat ride, a cave visit and a swim stop (in warmer months).
- Evening activities such as a cooking demonstration, squid fishing or a film on deck.
- Sunrise tai chi on the sundeck, then brunch while sailing back.
Drinks are usually extra and can be expensive on board, so check the price list before you go.
How to choose the right boat
There are dozens of boats, and the photos online all look similar. These are the questions we ask before we recommend one:
- How many cabins? Boats with 10–20 cabins feel more personal than large ships with 40+.
- Which route exactly? Ask for the itinerary map, not only the bay name.
- What is the cabin size? Anything from 20 m² upwards feels comfortable.
- Is there a balcony? Worth the upgrade for honeymooners.
- How are dietary needs handled? Vegetarian, vegan, gluten-free and allergies should be confirmed in writing.
Best time for a bay cruise
October to December and March to May offer the best weather. In winter the sea is calm but mornings can be misty and cool; in summer it is hot, with occasional storms. Between August and October the authorities may suspend cruises for a day if a typhoon approaches — a flexible local operator will rebook you or arrange an alternative, such as Ninh Binh.
Typical cruise prices
As a rough guide, a quality overnight cruise costs from around €150 to €400 per person in a twin cabin, depending on the boat, the season and the cabin type. Private charters for families or small groups start higher but can be surprisingly good value when shared.
A typical overnight cruise, hour by hour
| Time | Day 1 | Day 2 |
|---|---|---|
| 08:00 | Pick-up from your Hanoi hotel | 06:00 Sunrise tai chi on the sundeck |
| 11:30 | Arrival at the harbour, welcome drink, cabin check-in | 07:00 Light breakfast, visit a cave or floating village |
| 12:30 | Lunch while cruising among the islands | 09:30 Check out, brunch while sailing back |
| 15:00 | Kayaking or bamboo boat, cave visit, swim stop | 11:00 Disembark and drive to Hanoi or Ninh Binh |
| 17:30 | Sunset party on deck, cooking demonstration | — |
| 19:30 | Dinner, then squid fishing or relaxing on deck | — |
Two nights: is it worth it?
For most travellers one night is enough. A second night makes sense if you love kayaking, want to explore the remote lagoons of Lan Ha or Bai Tu Long, or are travelling with children who would enjoy a more relaxed pace. On two-night cruises, boats usually go further from the main routes, and the second day is spent almost entirely on the water.
Private charters for families and small groups
If you are travelling as an extended family, with friends or as a small incentive group, consider chartering a whole boat. Smaller junks with four to eight cabins can be privately booked, giving you full control of the route, the menu and the timing. For groups of eight to sixteen people the price per person can be close to that of a premium shared cruise.
Sustainability on the bays
Ha Long Bay has faced pressure from tourism and plastic waste. The authorities have introduced rules on waste management and limited the number of operators on some routes, and the better cruise companies have invested in water filtration, refillable bottles and waste separation. When we select boats, we look at these practices as well as comfort and food. You can help by refusing single-use plastic and choosing a cruise with a responsible environmental policy.
What to pack for your cruise
- A small overnight bag — main luggage can often be stored at the harbour or sent on with your driver.
- Swimwear, a quick-dry towel and water shoes for kayaking.
- A light jacket or fleece from November to March.
- Sunscreen, sunglasses and a hat.
- Motion-sickness tablets if you are sensitive, although the water is usually calm.
- A dry bag for your phone while kayaking.
Frequently asked questions
Is Ha Long Bay worth it?
Yes — it is one of the most spectacular landscapes in Asia. Choosing the right route and boat makes the difference between a crowded day and a magical one.
Is one night enough?
One night is enough for most travellers. Two nights let you go deeper into Lan Ha or Bai Tu Long with more kayaking and village visits.
Can children join a cruise?
Most boats welcome children, and some offer family cabins and connecting rooms. Kayaking is usually possible from about age six with a parent.
Do I get seasick?
The bays are sheltered and the water is usually calm, so seasickness is rare.
Can we combine a cruise with Ninh Binh?
Yes — many of our itineraries drive from the harbour straight to Ninh Binh after the cruise, avoiding a return trip to Hanoi.
Is there Wi-Fi on board?
Most boats offer Wi-Fi, but the signal can be weak among the islands. Many guests enjoy being offline for a night.
