Biak is both an island and a town off the north coast of Papua, sitting in Cenderawasih Bay. The town itself is compact and not especially scenic, but Biak is one of the main transport hubs for the region, with regular flights to Jayapura and Jakarta.
The island has a rich World War II history. Japanese soldiers hid in caves that you can still visit, and the Cenderawasih Museum has a collection of wartime relics and Papuan artifacts worth an afternoon.
The best beaches are at Bosnik on the east coast, good for swimming and snorkelling, and Korem on the north coast, where you can watch young men dive for pearls. Further out, the Wapsdori Waterfalls near Wardo make a good day trip by boat. Supiori Island, just north of Biak, has a recreation forest and welcoming villages.
