Bai Tu Long Bay is the name of an area located in the east of Halong Bay Vietnam. Although it shares many similar geological characters with Halong Bay, Bai Tu Long Bay is considered as off the beaten tourist track with many deserted and pristine beaches, no less impressive karst mountains. The Bay has a rich biodiversity with two ecosystems: a tropical, moist, evergreen rainforest ecosystem; and a marine and coastal ecosystem. The area has scarcely seen any tourist development. A large number of guests, through online research, wish to visit the Bai Tu Long Bay because it is much less crowded than Halong Bay. The only disadvantage is that it does not have many grottos. The nearest place for a visit (Vung Vieng Fishing village) is at around 20 km from tourist port.
