Bai Tu Long bay is located in the Gulf of Tonkin and in Quang Ninh. The bay includes a part of the sea of Ha Long city, a part of the sea of Cam Pha city, and a part of the sea of Van Don island district.

Bai Tu Long bay borders Ha Long to the southwest, the South China Sea to the east, the mainland of Cam Pha city to the west, and Co To island district to the northeast. Bai Tu Long bay consists of hundreds of islands, both large and small, many of which are large and inhabited.

If Ha Long Bay is a splendidly beautiful girl, Bai Tu Long bay is a pristine and full of charm girl. Together with Ha Long Bay, Bai Tu Long becomes one of the natural wonders of the world. Due to the beautiful islands and long white sand beaches that retain the wild appearance and pristine nature of the creation, Bai Tu Long bay increasingly attracts foreign visitors.

In the bay, there is also a special island that is under the management of the Ministry of Health that visitors cannot come to. That place is Monkey island, which is not far from Cam Pha city. Monkey island is currently raising about 1.000 monkeys of Macaca mulatta species to serve the research on vaccines against many diseases and is also the subject of research and testing many other scientific topics.

Furthermore, there is also a fishing village where visitors can learn more about the lives of people on the bay. The fishing village is about 30 minutes away from Cam Pha city as you're going by boat from Nuoc Duc wharf, which develops a model of cage farming for aquaculture and seafood.

Tourists can choose the fresh fishes from the cages to buy as gifts. Fishermen here raise a variety of high-value caged fishes such as grouper, cobia, tigerfish ... with the price from 200.000 dongs per kg./.
