Ha Long Bay & Karst Seascapes

Ha Long Bay is Vietnam's signature landscape: around 1,600 limestone karsts rising from the Gulf of Tonkin, a UNESCO World Heritage Site since 1994. The classic experience is an overnight cruise, sleeping among the islands.
The bay has three faces: busy Ha Long Bay itself, quieter Bai Tu Long Bay to the northeast, and Lan Ha Bay off Cat Ba Island to the south. On land, Ninh Binh's Trang An offers the same karsts with rivers instead of sea.
