Halong Bay Information

Local legend has it that long ago, when the Vietnamese were fighting Chinese invaders, the gods sent a family of dragons to help 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, 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).

Ha Long Bay is in northeastern Vietnam, from E106°56' to E107°37' and from N20°43' to N21°09'. The bay stretches from Yên Hưng district, past Hạ Long city, Cẩm Phả town to Vân Đồn district, bordered on the south and southeast by the Gulf of Tonkin, on the north by China and on the west and southwest by Cát Bà island. The bay has a 120 kilometre long coastline and is approximately 1, 553 square kilometres in size with about 2000 islets. The area designated by UNESCO as the World Natural Heritage Site includes 434 km² with 775 islets, of which the core zone is delimited by 69 points: Đầu Gỗ island on the west, Ba Hầm lake on the south and Cống Tây island on the east. The protected area is from the Cái Dăm petrol store to Quang Hanh commune, Cẩm Phả town and the surrounding giants zone.

The bay is a sea islands in tropical wet with 2 seasons: hot and moist summer, dry and cold winter. Average temperature is from 15°C- 25°C. Annual rainfall is between 2000mm and 2200mm. Ha Long Bay has the typical diurnal tide system (tide amplitude ranges from 3.5-4m). The salinity is from 31 to 34.5MT in dry season and lower in rainy season.

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 Ha Long 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 stalagmites (as well as 19th century French graffiti). There are two bigger islands, Tuần Châu 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 lizards also live on some of the islands.

Almost these islands are individual towers in a classic fenglin lanscape which height is from 50m to 100m and height/width ratios up to about 6.

Another specific feature of Halong Bay is the abundance of lakes inside the limestone islands, for example, Dau Be island has six enclosed lakes. All these island lakes occupy drowned dolines within fengcong karst.

A community of around 1600 people live on Ha Long Bay in four fishing villages: Cửa Vạn, Ba Hang, Cống Tàu and Vông Viêng in Hùng Thắng commune, Hạ Long city. They live on floating houses and are sustained by capture fishing and marine aquaculture (cultivating marine biota).

In 1962 the Vietnam Ministry of Culture, Sport and Tourism designated Ha Long Bay a 'Renowned National Landscape Monument'.

Ha Long Bay was first listed as a UNESCO World Heritage Site in 1994 [1], in recognition of its outstanding, universal aesthetic value. In 2000 the World Heritage Committee additionally recognised Ha Long Bay for its outstanding geological and geomorphological value[2], and its World Heritage Listing was updated.[3]

The New Open World Foundation has included Halong Bay on its list for nomination as one the World's 7 Natural Wonders.
