Simpson Harbour Wreck Diving
Simpson Harbour
A flooded volcanic crater harbor where dozens of Japanese ship and aircraft wrecks from World War II lie on the seabed. A renowned wreck-diving site.
Simpson Harbour is a natural deep-water harbor formed when the sea flooded the Rabaul caldera. During World War II, Allied air raids sank many Japanese transport ships, barges and aircraft in the harbor. Some wrecks, including the Hakkai Maru and George’s Wreck, lie within diving depth, and their hulls are covered with coral and sponges. Book through a dive centre in Rabaul or Kokopo; double-tank dives start at about PGK 400. Snorkelers can also see the remains of Zero fighter planes in the shallow water.
