Ha Long Bay

Ha Long Bay, in the Gulf of Tonkin, includes some 1,600 islands and islets, forming a spectacular seascape of limestone pillars. Because of their precipitous nature, most of the islands are uninhabited and unaffected by a human presence. The site s outstanding scenic beauty is complemented by many nature lovers. The bay features thousands of limestone karsts and isles in various sizes and shapes. The limestone in this bay has gone through 500 million years of formation in different conditions and environments. The evolution of the karst in this bay has taken 20 million years under the impact of the tropical wet climate. Ha Long Bay is home to 14 endemic floral species and 60 endemic faunal species. Historical research surveys have shown the presence of prehistorical human beings in this area tens of thousands years ago.
