Located east of Halong Bay and closed to Chinese border, Bai Tu Long Bay is off the beaten tourist track.
As it is not so near to the popular Cat Ba Island which has lodging, beaches and nearby caves in Halong Bay, the area has scarcely seen any tourist development. The Bay has a rich biodiversity with two ecosystems: a tropical, moist, evergreen rainforest ecosystem; and a marine and coastal ecosystem.
According to legend, an immense dragon descended to Halong Bay (meaning “Descending Dragon”) millions years ago, dropping numerous eggs. These eggs hatched forming thousands of rocks and islands. The tail of the dragon extended far to the sea, forming Bach Long Vi (meaning “The Tail of the White Dragon”). As she returned to heaven, she said good bye to her offspring at the Bai Tu Long Bay (means “The dragon parts the offsprings”).
Notable attractions in Bay Tu Long Bay are Vung Vieng fishing village, Quan Lan Island, Ngoc Vung Island, Van Don Island. The bay is also home to the large Bai Tu Long National Park. It is one of seven Vietnamese amphibian national parks which has both terrestrial zone and aquatic zone.
