The Halong bay

The Halong bay

country : Vietnam

place : in the Tonkin Gulf, east of Hanoi


The end of the Vietnam war, and the advent of "Doi moi", Vietnam's policy of opening its economy to foreign trade, means that Westerners and South Vietnamese now have a chance to visit Ha long.
Vinh Ha Long or Bay of the Descending Dragon is often touted by proud Vietnamese as the world's Eighth wonder. One of the main attractions of Ha long is the bay's calm water and the thousands of limestone mountains dotting the seascape.
The Bay's water is clear during the spring and early summer.
Some of the islands are quite large and there are small alcoves with sandy beaches where swimming is possible. Ha Long bay lies in the northeastern part of Vietnam and is 165 Km from Hanoi.

Ha Long literally means descending dragon(s) and according to local myth, the story goes as follows:
Long ago when their forefathers were fighting foreign invaders from the north, the gods from heaven sent a family of dragons to help defend their land. This family of dragons descended upon what is now Ha Long bay and began spitting out jewels and jade.

Upon hitting the sea, these jewels turned into the various islands and islets dotting the seascape and formed a formidable fortress against the invaders. The locals were able to keep their land safe and formed what is now the country of Vietnam.
 The Dragon family fell so much in love with this area for its calm water and for the reverence of the people of Vietnam that they decided to remain on earth.
Mother dragon lies on what is now Ha Long and where her children lie is Bai Tu Long.The dragon tails formed the area of Bach Long Vi known for the miles of white sandy beaches of Tra Co peninsula.
This myth is in line with the Vietnamese myth of their origin Con Rong Chau Tien. This myth describes the union between a king (representing the dragon) and his bride (representing a goddess) giving birth to 100 children which are the ancestors of the Vietnamese people. The Ha Long myth illustrate the Vietnamese belief of their origin and the fact that throughout their history, they are aided by their ancestors, the dragon and the gods, in the defense of their land.


Location

Hạ Long Bay is located 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 km long coastline and is approximately 1,553 km² in size with about 2,000 islets. 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: 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 zone.

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


Located in Hạ Long and Bái Tử Long are archaeological sites such as Mê Cung and Thiên Long. There are remains from mounds of mountain shellfish (Cyclophorus), spring shellfish (Melania), some fresh water mollusc and some rudimentary labour tools. The main way of life of Soi Nhụ's inhabitants included catching fish and shellfish, collecting fruits and digging for bulbs and roots. Their living environment was a coastal area unlike other Vietnamese cultures, for example, like those found in Hoà Bình and Bắc Sơn.

Located in Hạ Long and Cát Bà island, its inhabitants developed to the level of sea exploitation.

History shows that Hạ Long Bay was the setting for local naval battles against Vietnam's coastal neighbors. On three occasions, in the labyrinth of channels in Bach Dang river near the islands, the Vietnamese army stopped the Chinese from landing. In 1288, General Tran Hung Dao stopped Mongol ships from sailing up the nearby Bach Dang River by placing steel-tipped wooden stakes at high tide, sinking the Mongol Kublai Khan's fleet.

During the Vietnam War, many of the channels between the islands were heavily mined by the United States navy, some of which pose a threat to shipping to this day.


Ecology

Halong Bay is host to two ecosystems: a tropical, moist, evergreen rainforest ecosystem; and a marine and coastal ecosystem. The bay is home to seven endemic species: Livistona halongensis, Impatiens halongensis, Chirita halongensis, Chirita hiepii, Chirita modesta, Paraboea halongensis and Alpinia calcicola.

The many islands that dot the bay are home to a great many other species, including (but likely not limited to): 477 magnoliales, 12 pteris, 20 salt marsh flora; and 4 amphibia, 10 reptilia, 40 aves, and 4 mammalia.

Common aquatic species found in the bay include: cuttlefish (mực); oyster (hào); cyclinae (ngán); prawns (penaeidea (tôm he), panulirus (tôm hùm), parapenaeopsis (tôm sắt), etc.); sipunculoideas (sá sùng); nerita (ốc đĩa); charonia tritonis (ốc tù và); and cà sáy.
Environmental damage

With an increasing tourist trade, mangroves and seagrass beds have been cleared and jetties and wharves have been built for tourist boats.

Game fishing, often near coral reefs, is threatening many endangered species of fish.

Local government and businesses are aware of problems and many measures have been taken to minimize tourism affect to the bay environment for sustainable economic growth.
