Spend a full day exploring Lan Ha Bay from Cat Ba: swim in emerald waters, kayak among karst towers and visit Viet Hai Village. This active boat cruise balances relaxed cruising with hands-on water time and local culture.
More ways to explore the area's outdoor wonders
You step onto the teak deck as the boat slips away from Cat Ba harbor, limestone islets rising like carved monoliths from emerald water. The wind pulls at your hair and the bay answers, its surface daring you to dive in. Small fishing houses drift past, nets creaking; gulls wheel and call, following the wake.

Cai Beo and nearby fishing settlements have existed for centuries; the bay’s karst formations formed over millions of years and supported local fishing cultures long before tourism.
Conservation
Lan Ha Bay is ecologically sensitive—choose operators who use non-motorized village transport and discourage littering; reef-safe sunscreen helps protect marine life.

Bring a dry bag
Keep phones and spare clothes dry during kayaking and open-water swims; small waterproof pouches are often not enough.
Sun protection matters
Use reef-safe sunscreen and a wide-brim hat—sun reflects strongly off the water and shade can be limited on deck.
Wear water shoes
Rocky shores, ladder climbs and slippery boat decks make closed-toe water shoes a smart choice.
Listen to safety briefings
Life jackets are required for open-water activities—follow the crew’s instructions for launching and returning to the boat.
