Ha Long Bay Day Cruise from Cat Ba
Both bays in one day. Cruise the quiet Lan Ha channels in the morning, cross into Ha Long, with a cave, a kayak and lunch cooked on board.
At a glance
Ha Long and Lan Ha were listed together by UNESCO in 2023 as one bay of 1,133 islands. Most visitors see it from Hanoi, in a queue of large boats. Starting from Cat Ba turns the day around: your morning belongs to the quieter Lan Ha channels, where the big cruise ships don't fit, and you cross into Ha Long itself with the cave, the kayak and the swim still ahead of you. One boat, one guide, lunch cooked on board, back in town for the evening.
08:00 to 16:00
Highlights
- Cruise both Lan Ha and Ha Long scenery in one day from Cat Ba
- Paddle through a low cave into a still lagoon ringed by cliffs
- Kayaking and a swim stop in sheltered water
- Seafood lunch cooked in the boat's kitchen
- Hotel pickup and drop-off in Cat Ba Town, no boat night
The route

Why we chose this trip
This is the easiest boat day we sell, and we keep it honest about what it is: a full loop of both bays rather than a deep paddle into one. Sixteen guests is bigger than our other boats, and in return you get both seascapes, the cave and the crossing in a single day. We send families here first: the pace is gentle, and when you tell us your children's ages the crew brings the right life jackets.
The day, as it really runs
Pickup in town
Hotel pickup in Cat Ba Town, or tea at our house at 70 Tung Dinh if you're staying close.
Out among the karsts
Board at the pier and cruise into the Lan Ha channels, past islands the big boats don't reach.
Cave or lagoon
Visit a hidden cave or a lagoon, depending on the tide that day.
Kayak and swim
Short, flat-water paddling, then a swim stop off the boat. Both are optional.
Lunch on board
Seafood lunch cooked in the boat's kitchen while you keep cruising.
Deck time
Relax on deck as the boat cruises back through the islands, past a working floating village.
Back to town
Return to the pier and hotel drop-off, in time to rest before dinner.
Times shift with the tide, the weather and how the group is feeling. On a good day the captain gives you a longer swim instead of keeping to the clock.

Is this day right for you?
The honest version.
A good fit if
- You want to say you have seen Ha Long Bay, without giving it two days or a night on a boat.
- You prefer an easy day on the water: short optional kayaking, one swim stop, plenty of deck time.
- You are travelling with children or parents and want the gentlest boat day we run.
Tell us early if
- You get seasick easily. Tell us and we will suggest the calmest month and a seat near the middle of the boat.
- You are set on kayaking a lot. The paddle here is short and optional; the Lan Ha day trip gives you about 90 minutes.
- You are travelling in July or August. Keep a spare day in case storms close the bay.
