Introduction — answer first

Travellers ask: "What are the best beaches in Lan Ha Bay?" Monkey Island (Cat Dua) and Ba Trai Dao ("Three Peaches" beach) are the best-known boat-accessible coves, reached by tender from your cruise as part of the standard itinerary — different from the walkable Cat Co beaches on Cat Ba town, which suit travellers not booking a cruise.

Boat-accessible beaches

Monkey Island (Cat Dua)

A small islet with a short white-sand beach and a resident troop of wild monkeys — keep food sealed and belongings close, as the monkeys are habituated to visitors and will investigate open bags. A short optional hike leads to a viewpoint over the surrounding karst.

Ba Trai Dao ("Three Peaches" beach)

Three small connected coves inside a sheltered inlet, popular for calm-water swimming stops on overnight cruise itineraries. Access is sometimes tide-dependent — confirm with your operator if visiting is a priority.

Other cruise swim stops

Many itineraries include an unnamed cove swim break rather than a named beach — operators choose based on weather, tide and crowding that day. Ask your cruise which named beach (if any) is on the planned route before booking if a specific beach matters to you.

Closing — different beach, different trip

Lan Ha Bay's boat-accessible beaches suit travellers already on an overnight cruise; if you want a beach base without booking a boat, Cat Ba town's Cat Co beaches are the better fit. Either way, protect the reef by packing reef-safe sunscreen — more on why in the Lan Ha Bay conservation guide.
