Things to do in Halong Bay
Emerald waters and thousands of limestone karst islands
A favourite for honeymoons
Halong Bay is a UNESCO seascape of nearly 2,000 limestone islands rising from emerald water — one of Vietnam’s defining sights and the country’s top overnight-cruise destination. Most visitors come from Hanoi on a one- or two-night junk-boat cruise that takes in caves, kayaking and a night moored among the karsts.
A private cabin among the karsts at sunrise — one of Asia’s most romantic cruises.
Time needed
1–2 nights (a cruise) or a long day trip
Best time
October–April for cooler, drier, clearer days

Overnight cruise among the karsts
The classic experience: a traditional-style junk boat for one or two nights, sailing between the limestone towers, with kayaking, a cave visit and sunrise tai chi on deck. An overnight beats a rushed day trip and reaches quieter water.

About 2.5–4 hours’ drive from Hanoi (a new expressway has cut the time); most cruises include a shuttle transfer. Boats leave from Halong City / Tuan Chau, or from Haiphong/Cat Ba for Lan Ha Bay.
Best time to visit
October–April for cooler, drier, clearer days. Summer (June–August) is hot and the typhoon season can disrupt sailings; March–April and October are the sweet spots.
Halong Bay tips
- Choose your cruise operator carefully — quality varies hugely, so read recent reviews.
- For fewer crowds, pick a route into Lan Ha Bay or Bai Tu Long Bay rather than the central bay.
- Build slack into your plans — sailings can be cancelled in bad weather for safety.
