What This Site Is
Halong Bay Boat Cruise compares the cruises in Ha Long, Lan Ha and Bai Tu Long bays that are sold on GetYourGuide: day boats from Hanoi and Cat Ba, one night on board, two nights, luxury ships and private boats. We read every listing and put the same facts side by side, so you can see what a cruise gives you before you open the calendar.
The one number we add is hours on the water: how much of the trip you spend on the bay, not on the road or at the pier. A day from Hanoi gives about 6 of 13 hours; one night gives about 23 of 31. Where the partner publishes times we use them, and elsewhere we say it is our estimate.
