The broad sweep of Cenderawasih Bay, off the northern coast of Papua, is known for its spectacularly biodiverse coral reefs.

Jayapura, also known as Port Numbay, is the capital of Indonesia’s Papua province. This busy city is well off the tourist trail, and provides an introduction to the fascinating customs of the region.

The legendary Sepik River takes you into the remote and unspoilt heart of Papua New Guinea, a place where headhunting and cannibalism existed within living memory.

Madang, first settled by Germans during the 19th century, was once known as the ‘prettiest town in the Pacific’, and retains its charm despite significant damage during the Second World War.

Alotau is the capital of Milne Bay province, on the remote eastern tip of mainland Papua New Guinea.
