Bandarban district is situated beside the Sangu river. The district has execellent natural beauty and various kinds of hills . After Boman king Sathan Pru came here, people came to live here. Many people thought that there was a water fall in the opposite side of the district. The monkeys went there for drinking water. When they crossed the river it seemed to a Dam Of Monkey. And thats why the name of the district is Bandarban.
