The first decision is time. A day trip from Hanoi squeezes 4 hours of cruising out of a 12-hour day, so you spend more time on the road than on the water. An overnight cruise is the standard for a reason: you see the bay at sunset and sunrise, kayak, and avoid the day-trip crunch. If your schedule allows, book one night aboard and treat the extra cost as the whole point of the trip.

Day trip vs overnight
The first decision is time. A day trip from Hanoi squeezes 4 hours of cruising out of a 12-hour day, so you spend more time on the road than on the water. An overnight cruise is the standard for a reason: you see the bay at sunset and sunrise, kayak, and avoid the day-trip crunch. If your schedule allows, book one night aboard and treat the extra cost as the whole point of the trip.
Bay choice: Halong, Bai Tu Long or Lan Ha
Three bays share the same limestone scenery but differ in crowds. Halong Bay proper is the busiest and most photographed; Bai Tu Long Bay sits to the north-east and is calmer; Lan Ha Bay, off Cat Ba, is the quietest and best for kayaking. Many “Halong” cruises now sail Lan Ha to escape the fleets. Choose one night in Lan Ha or Bai Tu Long if you want fewer boats in your photos.
Booking tips
Book a cruise with a named boat, not just the bay, and check the cabin type and itinerary. Mid-range overnighters run about $120-250 per person including meals and transfers; budget cruises from $40-120 trade comfort and route for price. Book at least 3-5 days ahead in the October to April high season, and confirm whether the Hanoi transfer and kayaking are included.

Frequently asked questions
Is a Halong Bay day trip worth it or should I stay overnight?
Stay overnight if you can. A day trip spends about 8 of its 12 hours in a bus, leaving roughly 4 hours on the bay. An overnight cruise adds sunset, sunrise, kayaking and much less crowding, and is the standard choice for most travellers.
Which is better, Halong Bay or Lan Ha Bay?
They share the same karst scenery, but Halong Bay is busiest and Lan Ha Bay (off Cat Ba) is the quietest and best for kayaking. If fewer boats and a calmer route matter to you, choose a Lan Ha or Bai Tu Long overnight cruise.
How much does a Halong Bay cruise cost?
Day trips run about $40-70 per person with transfers; budget overnight cruises $40-120; comfortable mid-range one-night cruises $120-250 including meals and kayaking. Prices were checked October 2026 and rise in the high season and on holidays.
Should I book the cruise before arriving in Vietnam?
Yes, especially for overnight cruises in the October to April high season: book 3-5 days ahead and book a specific, named boat with good recent reviews. Day trips can usually be booked a day or two ahead through any Hanoi hostel.
When is the best time to cruise Halong Bay?
October to April is drier and cooler, the best window. December to February can be cold and misty but atmospheric. Summer brings storms that occasionally cancel cruises, and July to August is hottest and busiest with domestic tourists.
