Bio-diversity is an important natural resource and needs to be preserved and conserved to maintain the ecological balance of the whole region. Bio-diversity is the general term used to reflect diversify and abundance in nature and includes all living things.

Halong Bay’s geological value has been evaluated in two ways: by the history of its formation and by its karst geomorphology.

Halong Bay is located in the Northeast of Vietnam, belonging to QuangNinh Province. It is in the coastal area stretching from 1060 56’ to 1070 37’ east longitude and 200 43’ to 210 09’ north latitude. To the west and northwest, Halong Bay stretches  from Yen Hung District, and includes the large urban areas of Halong City and Cam Pha Town, as well as Van Don Island District. To the south and southeast, it is adjacent to the western Tonkin Gulf and to the west and southwest lies Cat Ba Island in the province of Hai Phong.  On the world map, Ha Long Bay borders to China in the north and in the east it is adjacent to the East Sea.

Halong Bay is one of the world's natural wonders and is the most beautiful tourist destination of Vietnam. Halong Bay features more than one thousand awesome limestone karsts and islands of various sizes and shapes along the 120-km coastline of Bai Chay Beach.
 

“Ha Long” is literally translated as "Bay of Descending Dragons." Prior to the 19th century, this name was not recorded in any document or archive. When mentioning the present-day Quang Ninh Sea or Ha Long Bay, old historical books often referred to them by the names of An Bang, Luc Thuy or Van Don.
