South of famous Hạ Long Bay, Cát Bà is the largest island in an archipelago of nearly 400 limestone islands and islets. Less crowded than its neighbour, Lan Hạ Bay unfolds jungle-covered karsts, hidden beaches and floating villages. Since 2023, the Cát Bà archipelago has been listed together with Hạ Long Bay as a UNESCO World Heritage Site. On the island, a national park protects the tropical forest and one of the rarest primates on Earth, the Cát Bà langur.

Understanding the destination

A jungle island in a listed seascape

Cát Bà belongs to the city of Hải Phòng, about 150 km east of Hanoi. More than half the island is covered by Cát Bà National Park, created in 1986 (about 17,000 ha, partly marine), itself at the heart of a UNESCO Biosphere Reserve designated in 2004.

The small town of Cát Bà, in the south of the island, gathers hotels, restaurants and boat departures; the Cát Cò beaches are a few minutes’ walk away. Opposite lies Lan Hạ Bay, with its floating fish farms and the old fishing village of Cái Bèo.

Things to see and do

Bay, forest and villages

The classic outing is a boat trip in Lan Hạ Bay: caves, lagoons, islets and swimming, by day or on an overnight cruise. Kayaking is now restricted by the authorities and often replaced by bamboo boats: check before booking. Cát Bà is also one of Asia’s great rock-climbing destinations, with more than 400 routes and deep water soloing.

On land, hike through the national park to Ngự Lâm Peak, visit the Vietnam War Hospital Cave and reach the remote village of Việt Hải by bike or boat.

Getting there and around

Direct flight to Hanoi, then bus and boat

Vietnam Airlines flies non-stop from Paris to Hanoi (about 11 h 30, daily). From Hanoi, combined bus + boat tickets reach Cát Bà in 3 h 30 to 5 h 30. You can also go via Hải Phòng (train or Cát Bi airport), then take the speedboat or the Cát Hải – Phù Long cable car, almost 4 km long. On the island, scooters, electric buggies, taxis and Grab are enough.

When to go

Spring and autumn

The best periods are mid-April to early June and October to November: calm sea, clearer skies and fewer crowds. Summer is hot (up to 34 °C) and rainy, with a risk of typhoons from July to September; winter is cool (15 to 20 °C) and often misty. Avoid Vietnamese weekends and public holidays, which are very busy.
