A geological wonderland of ancient coral and curiously eroded karst at the wild edge of Bai Tu Long.
Cong Dam is one of the most pristine corners of the entire Ha Long ecosystem, known for its fossilised coral, lagoons and oddly sculpted limestone.
Reached only by the longer Bai Tu Long cruises, it offers kayaking and snorkelling in water that feels untouched.

Who it suits
Nature and adventure lovers. The pace and accessibility still vary with weather, tide and the number of boats arriving at the same time.
How to see it at its best
Morning and late-afternoon visits are usually quieter than the middle of the day. Overnight cruises can reach popular landmarks outside the peak day-boat window, while two-night routes have more freedom to use the quieter hours.
Choose the route, not just the boat
Not every itinerary stops here even when it sails the same bay. Tell us this place matters to you and we will confirm which current routes include it before you book.
