Halong Bay

Ha Long Bay is located in the northeastern part of Viet Nam and constitutes part of the western bank of Bac Bo Gulf, including the sea area of Ha Long City, Cam Pha City and part of Van Don Island District, Quang Ninh Province.

Ha Long Bay covers a total area of 1,553km², including 1,969 islands of various sizes, 989 of which have been given names. There are two kinds, limestone and schist. The average geological age of the islands is between 250 and 280 million years old.

Geological Value

The most remarkable geological events of Ha Long Bay’s history in the last 1,000 years include the advance of the sea, the raising of the bay area and the strong erosion that has formed coral and pure blue and heavily-salted water. This process of erosion by sea water has deeply engraved the stone, contributing to its fantastic beauty. Present-day Ha Long Bay is the result of this long process of geological evolution that has been influenced by so many factors. It is because of all these factors that the tourists now visiting Ha Long Bay are not only treated to one of the true wonders of the world, but also to a precious geological museum that has been naturally preserved in the open air for the last 300 million years.

Biodiversity

Results of scientific research show that Ha Long Bay features ecosystems of a tropical ocean region such as ecosystem of coral reefs with 232 species of coral distributed mainly in the areas of Cong Do and Bo Hung. It is also home to 81 species of gastropoda, 130 species of bivalvia, 55 species of polycheta and 57 species of crab. The ecosystem of salt water-flooded forests chiefly concentrated in the zones of Tuan Chau, Cua Luc and Ba Che has the most diversified collection of species of salt water-flooded plant in North Viet Nam. Also living in this ecosystem are a great many species of animals: migrating birds (200 species), polycheta (169 species), seaweed (91 species), reptile (10 species). Ha Long Bay also has ecosystem of tropical rain forests with various rare and precious creatures: deer, weasels, squirrels and in particular, white-tabby and red-haired monkeys. In addition, there is a system of small caves along the sea, which are the living and development places for many animals and plants: seaweed, water plant, algae, fish and shrimp. Deeper into the water, there are also many species of shrimp, fish, abalone and other sea-specialities.

Historical and Cultural Value

Ha Long is a place closely linked to Viet Nam’s history with such famous geographical names as: Van Don (site of an ancient commercial port); Poem Mountain (with engravings of many poems by emperors and other famous people of the past); and Bach Dang River (the location of two fierce naval battles fought against foreign aggressors). This is not all, Ha Long has been proven by scientists to be one of the first cradles of human existence in the area, with such archaeological sites as Dong Mang, Xich Tho, Soi Nhu and Thoi Gieng…

Recognized by UNESCO as World Natural Heritage Site

On December 17, 1994, Ha Long Bay was recognised as world natural heritage for its natural beauty at the 18th meeting of the World Heritage Committee of UNESCO in Thailand.

On December 12, 2000, Ha Long Bay was recognised as world natural heritage for the second time based on its geological value at the 24th meeting of the World Heritage Committee of UNESCO in Cairns, Australia. The recognised site covers an area of 434km², comprises 775 islands and forms a triangle: with Dau Go Island (Driftwood Grotto) to the west; Ba Ham Lake (Three Shelter Lake) to the south and Cong Tay Island to the east.

The visitors exploring Ha Long Bay are treated to one of the true wonders of the world, enjoy interesting experience with kayaking, and take an overnight cruise on a tradition junk around the bay. There are many cruise tours with daily departure from Hanoi, with different amenities and itineraries. In general, there are a total of 3 cruise piers: cruises that set sail from Tuan Chau Pier visit the most classic part of Halong Bay, cruises that set sail from Hon Gai visit Bai Tu Long Bay, and cruises that depart from Hai Phong (Dinh Vu or Got pier) travel around Lan Ha Bay. Although differing by names, the latter two destinations still belong to the grand landscape of this world's wonder.
