Traditional ways of life still thrive in Halong Bay, despite the impact of tourism. One of the most fascinating is the fishing culture found in villages on the bay: Cua Van (the largest), Ba Hang, Vong Vieng and Cong Dau. These villages date back to the 19th century and residents still spend their days fishing and casting and repairing nets. Children practically learn to swim before they walk, while schools are in junks on the water. If you decide to visit, dress in comfortable clothes, good shoes, and bring your best traveling manners—you will effectively be visiting people's homes.
