There is a legend about the archipelago that in the old days when the Vietnam was attacked by foreign invaders, the God sent a mother dragon and its babies to support the Vietnamese people.
The dragons immediately blew out myriad pearls and gems that turned into grand rock mountains as a solid citadel to protect the Vietnam. After the foreign invaders were pushed away, the mother dragon and its babies did not return to the heaven but stayed in the lower world. The land where the mother dragon landed was then called Ha Long, and where the baby dragons landed called Bai Tu Long. The area where the dragon tails lashed was called Long Vi, nowadays Tra Co Peninsula, which consists of many long and smooth sand banks.
There are hundreds of islets rising from the water and many quirkily shaped rock mountains on Bai Tu Long Bayai??i??s site. Touring Bai Tu Long Bay, a day is not enough for visitors to discover these mysterious islets.
The Bai Tu Long National Park was formerly the 20km long and 1.5km wide Ba Mun Island. That island is part of Van Don District, some 60km away from Bai Chay Beach. The long island serves as a solid breakwater, preserving peaceful life for the whole region. The primeval layer consists of rare and precious woods like ironwood, teakwood, and canary-wood, while the second layer includes valuable herbs like araliaceous bark and rhubarb plant. The Ba Mun primitive forest is the habitat of a variety of fauna. Spotted deer with their smooth fur are the most famous species.
Taking advantage of Bai Tu Long Bayai??i??s attractions, many domestic travel companies both at home and abroad offer tours to the site. One of the best-selling tours brings visitors to the Bai Tu Long National Park, a fishing village at Minh Chau Island, Cai Lang, Thong Thien Cave, Phat Co Island, and finally returns to the shore to call at Cua Ong Temple and Van Hoa Port. Visitors can also go through thick forests to reach the habitat of ethnic minority groups (Dao Do, Tay, and San Diu minorities) and enjoy authentic local dishes.
Bai Tu Long Bay is every bit as beautiful as its famous neighbour. Indeed, in some ways itai??i??s more beautiful, since it has scarcely seen any tourist development. This has its positives and negatives. The bay is unpolluted and undeveloped, but thereai??i??s little tourism infrastructure. Itai??i??s pretty hard travelling around and staying here, and unless you speak Vietnamese, itai??i??s difficult to get information. Charter boats can be arranged to Bai Tu Long Bay from Halong Bay; a boat suitable for 20 passengers costs US$10 per hour and the one-way journey takes about five hours. A cheaper alternative is to travel overland to Cua Ong pier, catch a public ferry to Van Don Island and visit the remote outlying islands by boat from Cai Rong pier.
