UNESCO bay, limestone islands & overnight cruises
Ha Long
Hạ Long · Emerald bay of karst islands
Vietnam's most famous natural wonder — a UNESCO bay where nearly 2,000 limestone karst islands rise from jade-green water. Sail among the towering pillars on a traditional junk, explore sea caves and float past hidden lagoons and fishing villages.
