The back story

About Hạ Long Bay: limestone islands in the Gulf of Tonkin

UNESCO describes Hạ Long Bay – Cát Bà Archipelago, inscribed in 1994, as covering 65,650 hectares and including 1,133 islands and islets, a seascape of limestone rising from the sea in Quảng Ninh province and Hải Phòng city (whc.unesco.org). Most visitors drive from Hanoi to the cruise harbours and spend a night aboard; Lan Hạ Bay, off Cát Bà, is quieter.

Getting there

By car or shuttle on the expressway east from Hanoi to the cruise harbours; most cruise lines include the transfer.

On the water

Cruise lines such as Heritage Line, Orchid Cruises, Paradise, Ambassador and Emeraude sail overnight among the islands, with kayaking, caves and swimming stops.

Choose an overnight cruise: day trips spend most of the day on the road.

Safety

GOV.UK advises checking the safety record and registration of boats before an overnight trip, and making sure you get a safety briefing and a life jacket.
