Treasure Bay is a resort attraction in northern Bintan built around Crystal Lagoon, a huge filtered seawater lagoon with pale-blue water and shallow beach areas. The basic entry is mainly for swimming and lounging, while activities such as kayaking, slides, cable skiing, and other water sports cost extra.
It is not a natural beach, but it is one of Bintan's more visible family attractions and a practical stop for visitors staying in the resort belt.
