|Halong Bay (Vietnamese: Vịnh Hạ Long) is a UNESCO World Heritage site located in Quảng Ninh province, Vietna. The bay features thousands of limestone karsts and isles in various sizes and shapes.
Local legend says that long ago when the Vietnamese were fighting Chinese invaders, the gods sent a family of dragons to help to defend the land. This family of dragons began spitting out jewels and jade. These jewels turned into the islands and islets dotting the bay, linking together to form a great wall against the invaders. The people kept their land safe and formed what later became the country of Vietnam. After that, dragons were interested in peaceful sightseeing of the Earth and decided to live here then. The place where Mother Dragon flew down was named Hạ Long (originally spelled 下龍), the place where the dragon children attended upon their mother was called Bái Tử Long island (Bái: attend upon, Tử: children, Long: dragon), and the place where the dragon children wriggled their tails violently was called Bạch Long Vỹ island (Bạch: white- colour of the foam made when Children Dragon wriggle, Long: dragon, Vỹ: tail).

System of isles and caves
The bay consists of a dense cluster of 1,969 limestone monolithic islands, each topped with thick jungle vegetation, which rise spectacularly from the ocean. Several of the islands are hollow, with enormous caves. Hang Đầu Gỗ (Wooden stakes Cave) is the largest grotto in the Halong area. French tourists visited in the late 19th century, and named the cave Grotte des Merveilles. Its three large chambers contain large numerous stalactites and stalamites (as well as 19th century French graffiti). There are two bigger islands, Tuan Chau and Cat Ba, that have permanent inhabitants. Both of them have tourist facilities, including hotels and beaches. There are a number of wonderful beaches on the smaller islands.
Some of the islands support floating villages of fishermen, who ply the shallow waters for 200 species of fish and 450 different kinds of mollusks. Many of the islands have acquired their names as a result of interpretation of their unusual shapes: such names include Voi Islet (elephant), Ga Choi Islet (fighting cock), and Mai Nha Islet (roof). 989 of the islands have been given names. Birds and animals including bantams, antelopes, monkeys, and iguanas also live on some of the islands.

Geology and Geomorphology
History of Tectonics
Scientist said that Halong bay has experienced at least 500 million years in various of ancient geographic condition such as orogeny, marine transgression andmarine regression. In Ordovician and Silurian period (500-410 million years ago), Halong bay is deep sea. In Carboniferous and Permian period (340-250 million years ago), Halong bay is at shallow sea level
Vietnam government is submiting Halong bay in three times in Vietnam's Tentative list to UNESCO for its outstanding universal biodiversity value. The bay includes 2 ecosystem: tropical moist evergreen rainforest ecosystem and marine and coastal ecosystem with 7 endemic species.
