Last updated: 30 July 2026

Quick Summary: Lan Ha Bay is a calm, island-studded bay south of Ha Long Bay, with around 400 limestone karsts and far fewer boats. Beka Travel runs a day tour ($30), a 2D1N cruise ($99), and a 3D2N cruise ($239), all departing from Cat Ba. Best visited March-June and September-November for warm, calm days on the water.

Lan Ha Bay is a calm, island-studded bay on the southern edge of the UNESCO-listed Ha Long Bay – Cat Ba Archipelago. It wraps the coast of Cat Ba Island with around 400 limestone karsts and far fewer boats than neighboring Ha Long Bay.

What do you need to know about Lan Ha Bay before you go?

Lan Ha Bay sits on the quiet southern side of the same UNESCO seascape as Ha Long, wrapped around Cat Ba Island. It carries around 400 limestone karsts and a fraction of the boat traffic. Most visitors reach it in about four hours from Hanoi and see it on a day tour or an overnight cruise.

• Where it is: southern edge of the Ha Long Bay – Cat Ba Archipelago (a UNESCO World Heritage area), hugging the coast of Cat Ba Island in northern Vietnam.
• Scenery: around 400 limestone islands rising from calm, jade-green water, with secluded beaches and enclosed lagoons.
• Getting there: roughly 3.5 to 4 hours from Hanoi via Hai Phong; boats depart the bay from Ben Beo harbor, a short taxi from Cat Ba town.
• Best time to visit: March to June and September to November for warm, calm, sunny days on the water.
• Ways to visit: a 6–8 hour day tour, a 2 days 1 night cruise, or a 3 days 2 nights cruise.
• Reference prices with Beka Travel: day tour from 30 USD/person, 2D1N cruise from 99 USD/person, 3D2N cruise from 239 USD/person (low season, per person).

Why is Lan Ha Bay worth visiting?

Lan Ha Bay lies on the southern edge of the Ha Long Bay – Cat Ba Archipelago, a UNESCO World Heritage area, and hugs the coast of Cat Ba Island. Around 400 limestone islands rise from calm, jade-green water, hiding small beaches and enclosed lagoons between them.

Most travelers come here as a Ha Long Bay alternative. The scenery is the same family of karsts and sea, but the routes are quieter, the anchorages more private, and the pace slower. If your dream photo is a limestone bay without a queue of boats in it, this is the place.

Most visitors base themselves on the island, so our Cat Ba Island travel guide 2026 pairs naturally with this one. The mix works for almost every travel style. Adventurers get kayaking and swimming, culture lovers get floating villages and Viet Hai, and anyone who just wants to lie on a sundeck gets plenty of horizon to stare at.

When is the best time to visit Lan Ha Bay?

The most comfortable months for Lan Ha Bay are March to June and September to November. Days are warm and mostly sunny, the sea stays calm, and every water activity (kayaking, swimming, cruising) is at its best.

July and August are hot, lively high summer on Cat Ba, though June through September is also storm season, so keep an eye on the forecast. December to February turns cool and misty, which trades swimming for a quiet, romantic mood on the water: a lovely time for reading on deck with a coffee.

One planning note for cruise travelers: Beka's overnight cruise pricing follows the seasons too, with lower rates from May 1 to September 20 and peak rates from September 21 to April 30. Timing your trip right can save you money and crowds at once.

What happens if a storm cancels your cruise?

Storm season in the Gulf of Tonkin runs June through September, not the September to November window most guides quote for Vietnam as a whole. Northern Vietnam sees one to two landfalling storms in an average year, and each closes the ferry routes and stops boat trips for one to three days.

Closures are not an operator decision. The bay management board issues a stop order and it applies to every boat on the water that day, which is why nobody is out sailing while we sit in port.

When it happens you choose what comes next: a refund, a change of date, or an alternative route on land.

How do you get from Hanoi to Lan Ha Bay?

The journey from Hanoi takes roughly 3.5 to 4 hours in total. Most travelers take an express bus or limousine van from Hanoi's Old Quarter to Hai Phong, then a speedboat or ferry across to Cat Ba Island.

From Cat Ba town, it is a short taxi ride to Ben Beo harbor, where boats depart into the bay and entrance tickets are sold.

Booking a tour with transfers included is the simplest route: pickup in Hanoi, bus, boat, and boarding are handled in one package, so you never stand at a pier wondering which ticket window is yours.

What are the best things to do in Lan Ha Bay?

The bay rewards travelers who like being on, in, or beside the water. Kayaking into enclosed lagoons, swimming at Ba Trai Dao, and cycling through Viet Hai village are the three experiences visitors talk about most, and a well-planned cruise fits all three into a single itinerary without rushing any of them.

Kayaking through caves and enclosed lagoons

Kayaking is the signature activity of Lan Ha Bay. You paddle through low cave mouths and rock tunnels, then pop out inside silent lagoons walled entirely by cliffs, spaces only reachable by kayak or small sampan.

The water inside is calm and clear, and on lucky days you can spot wildlife on the cliffs, including the rare golden-headed langur that lives only on Cat Ba. No experience is needed; guides and equipment come with every good tour.

Swimming at Ba Trai Dao and quiet beaches

Dozens of small sandy beaches sit at the feet of the karsts, and most stay completely undeveloped. Ba Trai Dao is the favorite: shallow, clear water between three peach-shaped hills, reached by boat and often nearly empty.

Note that some beaches, Ba Trai Dao included, are only accessible at certain tide hours. Cruise itineraries plan around this, which is one more reason a well-run boat beats DIY logistics here. On Beka departures our crew times the Ba Trai Dao stop to the tide so you get to swim there.

Cycling to Viet Hai village

Tucked inside Cat Ba National Park, Viet Hai is a small farming village reachable only by boat or a long trek. Most visitors rent bicycles at the pier and ride a quiet, car-free road through jungle and rice fields to the village.

Expect mud-walled houses, water buffalo, a famous fish massage in a cool stream, and genuinely friendly locals. Read our full Viet Hai village guide if you want to add it to your route.

Which Lan Ha Bay cruise should you choose?

The right format depends on how much time you have and how deep into the bay you want to go. Here is how the three classic options Beka runs compare, with per-person pricing by season.

Beka Insight: Beka runs 2 boats, a day boat holding up to 48 guests (averaging 25-30 guests per departure) and an 11-cabin overnight boat holding up to 25 guests (averaging 22-25 guests per departure). Every cruise sails well under capacity, which is what keeps the "small-group" experience real rather than a marketing line.

Lan Ha Bay day tour

A Lan Ha Bay day tour packs the highlights into 6–8 hours: cruising past Cai Beo floating village, kayaking the lagoons, swimming at a quiet beach, and a fresh seafood lunch on board. Tours run to the less touristy corners of the bay, so even a single day feels unhurried.

It is the practical pick for travelers based on Cat Ba or short on time: you see the essential Lan Ha Bay and sleep on land.

Lan Ha Bay 2 days 1 night cruise

The 2D1N cruise adds the part day tours cannot: sunset and sunrise on the water. Evenings bring squid fishing with the crew and, on dark nights, glowing bioluminescent plankton. See our full guide for the best season and moon phase to catch it; mornings start with Tai Chi on the deck as the karsts wake up.

Pricing is per person and follows the season: 99 USD in the low season (May 1 to September 20) and 139 USD in the high season (September 21 to April 30). Cabins, meals, kayaking, and entrance tickets are included. Prefer land time over an extra night on board? Our 2D1N Adventure trip swaps the overnight cabin for cycling and a bungalow stay in Viet Hai village.

Lan Ha Bay 3 days 2 nights cruise

The 3D2N cruise sails further south into corners day boats never reach: isolated fishing communities, empty beaches, and long unhurried mornings. There is time for stand-up paddleboarding, cooking classes, and simply doing nothing at all.

It costs 239 USD per person in the low season and 310 USD in the high season, and suits travelers who want the bay to themselves for a while.

What should you pack and know before your trip?

Pack reef-safe sunscreen, a hat, and sunglasses; the light on open water is strong even on hazy days. Always wear the life jacket provided when swimming or kayaking, and bring a small amount of Vietnamese dong in cash for drinks and snacks at the harbors.

Layers matter outside summer: mornings on deck can be cool even when afternoons are warm. And please keep the bay as you found it, take all plastic back to shore and skip single-use bottles where refills are offered.

• Reef-safe sunscreen, hat, sunglasses. Light on open water is strong even on hazy days.
• Cash in Vietnamese dong. Harbour kiosks and drink stalls do not take cards.
• Layers outside summer. Mornings on deck run cool even when afternoons are warm.
• A dry bag. Kayaking gets your hands and anything in your lap wet.
• Motion sickness tablets if you are prone. The bay is sheltered, but the crossing out of Ben Beo can be choppy in a northeast wind.
• Nothing single-use. Take plastic back to shore and use the refills offered on board.

Frequently asked questions about Lan Ha Bay

Is Lan Ha Bay better than Ha Long Bay?

Both share the same UNESCO-listed karst seascape, but Lan Ha Bay has far fewer boats and quieter anchorages, since it sits on the calmer Cat Ba side of the archipelago. If avoiding crowds matters more than the famous name, Lan Ha Bay is the better choice.

How many days do you need in Lan Ha Bay?

One full day covers the highlights; a 2D1N cruise adds sunset, sunrise, and night activities; a 3D2N cruise reaches remote areas day boats skip. Beka Insight: international guests booking with Beka stay an average of 1.2 nights in the Cat Ba area, so most travelers choose the 2D1N format.

How much does a Lan Ha Bay cruise cost?

With Beka Travel, prices run from 30 USD per person for a day tour up to 239-310 USD per person for a 3D2N cruise, depending on season. See the season-by-season pricing table above for the full breakdown by cruise length.

Can you swim in Lan Ha Bay?

Yes: the water is clean, calm, and pleasant for swimming from roughly March to November. Beaches like Ba Trai Dao are ideal, and cruise boats stop specifically for swimming, timed around the tide where needed.

Ready to see Lan Ha Bay for yourself?

However you choose to explore, a single sunny day on the water or three slow days among the karsts, Lan Ha Bay rewards travelers who come curious. Pick your season, pack light, and let the bay set the pace.

When you are ready to book, the local team at Beka Travel runs and operates its own small-group cruises to the quiet corners of the bay, with pickup from Hanoi or Cat Ba and every detail handled for you. Browse the full Lan Ha Bay hub to compare every tour and cruise option in one place.
