Ha Long Bay has a 120 km long coastline and an area of around 1,553 km2, including 1,960–2,000 islets, most of which are limestone. The area designated by UNESCO as the World Natural Heritage Site incorporates 434 km² with 775 islets, of which the core zone is delimited by 69 points: Dau Go island on the west, Ba Ham lake on the south and Cong Tay island on the east.
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. The geo-diversity of the environment in the area has created biodiversity, including a tropical evergreen biosystem, oceanic and sea shore biosystem.
Historical research surveys have shown the presence of prehistoric human beings in this area tens of thousands years ago. Ha Long Bay also marked important events in the history of Vietnam with many artifacts found in Bai Tho Mountain, Dau Go Cave, Bai Chay.
