The Ha Long Bay is located on the Western side of the Gulf of Tonkin in Northeastern Vietnam. It has been an UNESCO World Heritage Site since 1994. The bay is famous for its more than 1960 limestone karsts and islets, which rise out of the waters of the bay to heights of up to 100 meters.
There are many names given to islands according to their shapes and forms such as Hon Dau Nguoi (Human Head Islet), Hon Rong (Dragon Islet), Hon Canh Buom (Sail Islet), Hon But (Pen Islet), Hon Dinh Huong (Dinh Huong islet) and Hon Con Coc (Toad Islet).
