Halong Bay vs Lan Ha Bay: Which Should You Actually Book?

Last updated: July 2026

Halong Bay and Lan Ha Bay sit on the same stretch of coastline, separated by an administrative border rather than anything you could see from a boat. The limestone towers are the same rock, the water is the same colour, and the two bays are close enough that a fast vessel crosses between them in under an hour.

Ask ten travel agents which one to book and you will hear ten versions of the same line: Lan Ha is the quiet one. That is broadly true today. It is also becoming less true each season, and very few operators will explain why.

We run our own boats on the Lan Ha side and resell cruises on the Halong side, which means we see both sets of manifests. What follows is the version we would give a friend.

Quick Summary: Book Halong Bay for the famous caves, the biggest ships, and the view you already have in your head. Book Lan Ha Bay for swimming, kayaking and small boats. Our Lan Ha Bay Day Tour (Beka Travel, from $30, max 30 guests) and Ha Long Bay Day Tour (from $34) sit within a few dollars of each other, so price is rarely the deciding factor.

What is the difference between Halong Bay and Lan Ha Bay?

Halong Bay sits in Quang Ninh province and holds the famous caves, the largest ships and the heaviest traffic. Lan Ha Bay sits off Cat Ba Island in Hai Phong, with more beaches, smaller vessels, and no single headline sight that everyone has heard of. They are two parts of one karst system split by a provincial line.

Most travellers can make their decision from that table alone. The rest of this page explains the reasoning behind each row, starting with the one that has changed most recently.

Are Halong Bay and Lan Ha Bay really the same UNESCO site now?

Yes, and this is the detail most comparison articles still get wrong. On 16 September 2023, decision 45 COM 8B.3 at the 45th session in Riyadh folded the Cat Ba Archipelago into the existing World Heritage site. The listing is now officially Ha Long Bay – Cat Ba Archipelago, under criteria (vii) and (viii).

Most older articles still use the earlier framing, in which Halong holds UNESCO status and Lan Ha is merely a member of a "most beautiful bays" association. That distinction stopped being accurate nearly three years ago.

Three things follow from the change:

• You are not trading down by choosing Lan Ha. Same listing, same protections, same geology.
• The scenery is not a lesser version of Halong. It is the same drowned limestone plateau a few kilometres south.
• The real difference is now about crowds, activities and boat size, not heritage status.

For the background on the site itself, our Halong Bay travel guide covers the geology and the 2026 rule changes in more depth.

Which bay is more crowded?

Halong Bay, by a wide margin. In 2025 the core Halong area received approximately 3.4 million visitors, including 2.2 million international tourists. Lan Ha takes a fraction of that, spread across a wider scatter of smaller boats.

There is a complication here that other comparison pages do not mention, and you should know about it before you book.

Lan Ha is getting busier deliberately. In March 2026 Quang Ninh and Hai Phong signed a joint management agreement covering cruise traffic across both bays, effective 1 April 2026. Published estimates put the effect at 5,000 to 6,000 additional visitors per day and more than 50 additional overnight vessels moving through the Lan Ha side.

So the honest position is this:

• Today, Lan Ha remains noticeably quieter, particularly outside the 10am to 2pm window.
• Over the next few seasons, that gap will narrow. It will not close, because the anchorages are smaller and the licences fewer, but it will narrow.
• If an empty bay is genuinely your priority, go sooner rather than later, and consider Bai Tu Long as a third option. Our Bai Tu Long Bay guide covers it.

Timing turns out to matter more than destination. A Halong route at 8am is calmer than a Lan Ha route at noon in August, because the crush at Sung Sot and Ti Top runs roughly 10am to 2pm, when the day boats and the overnight fleet overlap.

What can you actually do in each bay?

Halong Bay is organised around its caves, and Lan Ha Bay is organised around getting into the water. That single distinction settles the trip for most people, and it is worth understanding before you compare prices or ships.

On the Halong side, Sung Sot Cave is the largest cavern open to visitors, three chambers deep. Thien Cung is smaller but denser and more theatrical. Ti Top gives you the viewpoint that appears on every postcard, about 400 stone steps up from the beach.

On the Lan Ha side, the day is built around kayak routes, enclosed lagoons and small beaches you can actually land on.

Then there is a rule that catches almost everyone out. In the Halong core zone, Ti Top Island is the only beach where swimming is permitted. The bay has hundreds of beaches and you may use exactly one of them. On the Lan Ha side, stopping to swim is part of the standard route rather than an exception to it.

Kayaking is regulated in both bays. There are 8 designated kayaking areas under Decision 6643/QD-UBND (2017), and your captain cannot improvise outside the licensed route.

If swimming or kayaking ranks high on your list, that swimming rule should decide this for you.

How do the cruises compare?

The two bays attract different fleets, and the ship you board changes the trip more than the scenery does. Halong carries the large vessels with the facilities, while Lan Ha runs smaller boats that move faster and stop where they like.

The biggest ship we resell in Halong has 46 cabins. You get wide sundecks, a pool on some vessels, several dining options, and a longer wait every time a full manifest disembarks for a cave.

Our own boats in Lan Ha cap out at 15 to 25 guests depending on the trip. Tender transfers take minutes rather than half an hour, and the trade-off is fewer facilities and no pool.

That last row deserves a moment. In Halong we book you onto a partner's ship and the schedule belongs to them. In Lan Ha we run the boat, set the group size and choose when to leave an anchorage. That is why our Lan Ha trips can sit at a quiet cove for an extra hour and a large Halong ship cannot.

To compare individual vessels across both bays, see our guide on how to choose a Halong Bay cruise.

Which bay is cheaper?

Neither, at entry level. This tends to surprise people who assume the quieter bay carries a premium, but Lan Ha day tours and overnight cruises both start slightly lower than their Halong equivalents, because the boats are smaller.

Beka Travel prices, July 2026. Government sightseeing fees are set by the Ha Long Bay – Yen Tu World Heritage Management Board and charged per person.

Watch the ticket rather than the headline price. The government sightseeing fee sits outside your fare, and the cheapest street-booked day tours are cheap precisely because they leave it out. Ask one question before you pay: is the VHL ticket included?

How do you get to each bay?

Both bays are 2.5 to 3 hours from Hanoi on the expressway, so the drive is not a deciding factor. What differs is the pier, and arriving at the wrong one costs you the day.

• Halong Bay sails from Tuan Chau Marina or Hon Gai Port.
• Lan Ha Bay sails from Got Port in Hai Phong, or Ben Beo on Cat Ba Island.

Tuan Chau and Got are about 40 kilometres apart. If your driver takes you to the wrong one there is no second sailing. Get the pier name in writing when you book, not on the morning of departure.

Reaching Ben Beo involves one extra step, since you cross to Cat Ba Island first by ferry or cable car. That adds roughly half an hour to an hour. It is worth it if you are staying on the island anyway, and not worth it if you are only there for the boat.

Air options have gone from both bays. The Hanoi seaplane service stopped permanently on 1 April 2026, and helicopter sightseeing ended in 2023.

Which bay is better for you?

The right answer depends on what you want from the day rather than which bay is objectively better. Below is how we actually route guests when they call and ask us to choose for them.

Choose Halong Bay if you:

• Are visiting Vietnam for the first time and want the sights you have already seen in photographs
• Want a large ship with a pool, a proper bar and several restaurants
• Care more about caves than about swimming
• Are travelling with a group that wants room to spread out

Choose Lan Ha Bay if you:

• Want to swim and kayak rather than walk through caves
• Would rather share a boat with 20 people than 90
• Have seen Halong before, or have read enough about the crowds to want an alternative
• Care about who actually operates the boat you are on

Choose Bai Tu Long if neither of those is quiet enough for you. It is the least developed of the three and the furthest from Hanoi.

If you are still weighing it up, our Lan Ha Bay travel guide goes deeper on the southern option, and our Cat Ba Island travel guide covers the base you would be staying on.

Can you visit both bays in one trip?

Yes, and it has become easier. Since April 2026, the joint management agreement between Quang Ninh and Hai Phong has formalised cross-bay operations, so licensed vessels can now work both sides properly rather than turning back at the provincial line.

There are three practical ways to do it:

• A single day tour that crosses. Our Halong Bay to Lan Ha Bay day tour links both in one day, from $50.
• Split the trip. Take an overnight cruise in one bay and a day trip in the other. This works best with three days or more.
• The public ferry. Tuan Chau to Gia Luan, then continue independently. Cheapest, slowest and most flexible.

Our guide on getting from Halong Bay to Lan Ha Bay compares all three with times and costs.

Frequently asked questions

The questions below come up most often when guests are choosing between the two bays, particularly around the UNESCO change and the swimming rules.

Is Lan Ha Bay part of Halong Bay?

Not administratively, but they share a World Heritage listing. Lan Ha sits in Hai Phong province off Cat Ba Island, while Halong Bay sits in Quang Ninh. Since the UNESCO boundary expansion of September 2023, both fall inside the same protected site, Ha Long Bay – Cat Ba Archipelago.

Is Lan Ha Bay a UNESCO site?

Yes, since 16 September 2023. Decision 45 COM 8B.3 merged the Cat Ba Archipelago, which includes Lan Ha Bay, into the existing Halong Bay listing. Many older travel articles still say otherwise, because they were written before the expansion and have not been updated since.

Which bay is better for families with young children?

Halong Bay, usually, because the larger ships carry pools, connecting cabins and more onboard distraction. Lan Ha suits families with older children who want to kayak and swim. If your children are under about six, the bigger boat and the shorter walk to a cave generally makes for an easier day.

Which bay has better weather?

Effectively the same, since they are only a few kilometres apart. October to November and March to May are the best windows for both. July and August bring typhoon risk across the whole gulf, and the port authority grounds every fleet in both bays at once when a storm approaches.

Can you swim in Halong Bay?

Only at Ti Top Island in the core zone, which is the single permitted swimming beach there. Everywhere else in the core zone, swimming is not allowed. On the Lan Ha side, swimming stops are built into most standard routes rather than being an exception.

Is Lan Ha Bay cheaper than Halong Bay?

At entry level it is roughly the same or slightly cheaper. Our Lan Ha day tour starts at $30 against $34 for Halong, and Lan Ha overnight cruises start lower because the boats are smaller. The gap widens on longer trips, where Lan Ha tends to cost less per night.

Which bay should I choose for a first visit to Vietnam?

Halong Bay, if you only have time for one and you want the recognisable sights. It has the famous caves and the viewpoint everyone photographs. Choose Lan Ha instead if swimming and kayaking matter more to you than seeing landmarks you already know from photographs.

So which one should you book?

If you have never been to either, book Halong. See the caves, climb Ti Top and take the photograph. The bay earns its reputation even with the crowds attached.

If you have been before, or if the phrase "3.4 million visitors" gave you pause, book Lan Ha. You get the same heritage site, smaller boats, and water you are actually allowed to swim in.

And if you can spare an extra day, do both. The bays are neighbours, the crossing is straightforward, and they leave genuinely different impressions.
