How do I choose a 2-day, 1-night Lan Ha Bay cruise and is night kayaking worth it?

Lan Ha Bay is quieter than Ha Long Bay, and most cruises there leave from Cat Ba Island. For 2 days and 1 night, compare a short list of boats on the same points rather than on photos alone.

• Route and harbor. Check that the itinerary covers Lan Ha and not only the busy part of Ha Long Bay, and ask where the boat departs.

• What is included. Meals, kayaking, a cave or beach stop, transfers from Hanoi and entrance fees. The cheapest price often leaves some of these out.

• Group size and cabins. Smaller boats and family cabins suit teens better. Ask whether the ship has a family room or connecting cabins.

• Recent reviews. Read reviews from the last few months on more than one site.

Night kayaking is offered by only some operators. If it is available, it is a nice extra, but bioluminescence depends on the season and the plankton and is never certain. Ask how often guests see it in March.

Weather in March can be misty and cool, so pick a flexible booking. See our Vietnam travel guide for route planning, and apply for your e-visa before you book non-refundable tours.
