Quick answer
Ha Long Bay is a UNESCO-listed seascape of roughly 1,600 limestone islands and islets in Quang Ninh province, about 160 km east of Hanoi. Most visitors see it from a boat: day cruises and overnight junks leave Bai Chay and Tuan Chau for caves, kayaking lagoons and island viewpoints, while Cat Ba Island and the neighbouring Lan Ha and Bai Tu Long bays offer the same scenery with fewer boats. Ha Long city itself is a resort town split by a bridge between Bai Chay and Hon Gai. Plan 3 days for a first visit; the best months are April–May and October–November.

Why visit Ha Long Bay
- Several thousand forested limestone towers rise straight out of green water, a landscape listed by UNESCO for its scenery and geology.
- An overnight cruise lets you wake among the islands, kayak into enclosed lagoons and visit caves such as Sung Sot and Thien Cung.
- Cat Ba Island adds a national park with forest hikes, beaches and access to the quieter Lan Ha Bay.
- Fresh seafood is the local cuisine: Ha Long squid cakes, mantis shrimp, clams and oysters from Bai Tu Long Bay.
- The bay is reachable from Hanoi in about 2.5–3 hours on the expressway, so it fits even a short Vietnam itinerary.

When to go
The best months for Ha Long Bay are March to May and October to November, when skies are clearer, seas are calm and temperatures are comfortable for kayaking and hiking. Summer is hot and busy with a risk of typhoons that can cancel cruises, while winter is cool and often misty.
| Season | Months | What to expect |
|---|---|---|
| Spring | March–May | Mist gives way to clearer skies, the sea warms and crowds are moderate apart from the holidays around 30 April. |
| Summer | June–August | Hot, humid and the warmest water for swimming, but the wettest and busiest season, with typhoons that can stop all boats. |
| Autumn | September–November | Storms fade through September, leaving dry, clear and warm weather in October and November, the best time for views. |
| Winter | December–February | Cool, often grey and misty, with low prices outside Tết; too cold for swimming but fine for cruising in a jacket. |
Getting there and around
Most visitors fly into Hanoi's Noi Bai Airport (HAN), about 170 km away, and transfer by car, van or shuttle in about 2.5–3 hours. Van Don International Airport (VDO), about 50 km from Bai Chay, has a smaller number of domestic and some international flights and is under an hour by road.
The bay itself is seen by boat, either on an organised cruise or on day boats from Bai Chay, Tuan Chau or Cat Ba. On land, Ha Long city is spread out along the coast, so taxis and ride-hailing are the practical way between Bai Chay, Hon Gai and Tuan Chau.
Plan your days
A day cruise from Ha Long is possible but means about six hours on the road from Hanoi. One night on a cruise is the most popular option; two or three nights lets you combine a cruise with Cat Ba Island and Lan Ha Bay, or explore the quieter Bai Tu Long Bay.
