• Biak is the best-known of the former scouted island and the most populated. A town was built on the coral of the island. The island is rich in history and natural beauty such as Japanese soldier cave, and museum full of relics. Further out from the town, one encounters beautiful waterfalls and reefs. There are some good beaches on Biak Island, the most popular of which are Bosnik on the east coast, good for swimming and skin-diving, and Korem on the north coast, where one can watch young men dive for pearls. Supiori Island, just north of Biak, has a recreation forest and villages where visitors are welcome.
