Ha Long Bay

Ha Long Bay is located in the northeastern part of Vietnam and constitutes part of the western bank of Bac Bo Gulf, including the sea area of Ha Long City and Cam Pha Town and part of Van Don island district. It abuts Cat Ba Island in the southwest. Toward the west is the shore with a 120 km-long coastline. It is located within 106o58'-107o22' east longitude and within 20o45'- 20o50' north latitude. The site is 1553 sq. km with 1969 islands of various sizes, of which 989 have been named.

The islands in Ha Long Bay are mainly limestone and schist islands most lying in the two main areas: the southeastern part of Bai Tu Long Bay and southwestern part of Ha Long Bay. These islands represent the most ancient images of a geographical site having a tectonic age of from 250 million to 280 million years. They are the result of many times of rising and lowering processes of the continent to form a karst. The process of nearly full erosion and weathering of the karst created the unique Ha Long Bay in the world. In a not very large area, thousands of islands with different forms look like glittering emeralds attached to the blue scarf of a virgin. The area where many stone islands concentrate has spectacular scenes and world-famous caves and is the center of Ha Long Bay Natural Heritage, including Ha Long Bay and a part of Bai Tu Long Bay.

The area is recognized as the World Natural Heritage that is the area of 434 sq. km with 775 islands. It looks like a giant triangle with Dau Go Island (in the west), Ba Ham Lake (in the south) and Cong Tay Island (in the east) as its three angle points. The nearby area is the buffer area and areas classified as national beauty spots in 1962 by the Ministry of Culture and Information.
