The trekkers explore New Britain Island, the largest in the Bismarck Archipelago of Papua New Guinea. Inhabited by the indigenous Papuans and the Austronesians, the island was captured by the Japanese during World War II. Today the island’s traditional cultures are diverse and complex but there are several ancient traditions which remain active today. Next, we visit the township of Rabaul, once the provincial capital until it was destroyed in 1994 by a massive volcanic eruption.
