Halong Bay

Halong Bay

Hạ Long Bay is a UNESCO World Heritage Site, and a popular travel destination, located in Quảng Ninh province, Vietnam. The bay features thousands of limestone karsts and isles in various sizes and shapes.

The limestone in this bay has gone through 500 million years of formation in different conditions and environments. The evolution of the karst in this bay has taken 20 million years under the impact of the tropical wet climate. The geo-diversity of the environment in the area has created biodiversity, including a tropical evergreen biosystem, oceanic and sea shore biosystem. Hạ Long Bay is home to 14 endemic floral species and 60 endemic faunal species.

500 years ago, Nguyen Trai praised the beauty of Hạ Long Bay in his verse Lộ nhập Vân Đồn, in which he called it "rock wonder in the sky". In 1962, the Ministry of Culture, Sports and Tourism of Vietnam listed Hạ Long Bay in the National Relics and Landscapes publication. In 1994, the core zone of Hạ Long Bay was listed by UNESCO as a World Heritage Site according to criterion vii, and listed for a second time according to criterion viii.

               

Etymology

According to local legend, 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 then decided to live here. The place where the mother dragon descended was named Hạ Long, the place where the dragon's children attended upon their mother was called Bái Tử Long island (Bái: attend upon, Tử: children, Long: dragon), and the place where the dragon's children wriggled their tails violently was called Bạch Long Vỹ island (Bạch: white- colour of the foam made when Dragon's children wriggled, Long: dragon, Vỹ: tail).

Climate 

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.

System of isles and caves

The bay consists of a dense cluster of over 3,000 limestone monolithic islands (although locals claim there are only 1,969 as this is the year of Ho Chi Minh's death), each topped with thick jungle vegetation, rising 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 Hạ 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 beautiful 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 all these islands are as individual towers in a classic fenglin landscape with heights from 50m to 100m, and height/width ratios of up to about six.

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.

Inhabitants 

A community of around 1,600 people live on Hạ 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 through fishing and marine aquaculture (cultivating marine biota).

 

Tourist attraction

Hạ Long Bay is a famous tourist attraction in Vietnam. But several accidents happened in recent years due to low safety standards. In February 17 2011, twelve died when their tourist boat sunk. Most of them are foreign tourists, from Britain, Australia, France, Japan, USA, Russia, Sweden, and Switzerland. Many tourists also died in similar accidents in 2002, 2006, and 2009. According to BBC Vietnamese, some British and Australian tourists who visited Hạ Long Bay said that they are "lucky to still be alive", and they are not surprised when accidents happen, as all tourist boats are "very old"
