Simpson Harbour

Simpson Harbour, a deep natural harbour on the coast of New Ireland Province in Papua New Guinea, is a captivating blend of wartime history, vibrant local culture, and pristine tropical beauty. The harbour is best known as the site of the Japanese occupation during World War II and the subsequent Allied bombing raids that left numerous shipwrecks beneath its waters. Today, it offers exceptional diving, a chance to explore traditional villages, and stunning volcanic landscapes.

Highlights & What to See

• Wreck Diving: Simpson Harbour is a world-class wreck-diving destination, with dozens of Japanese ships and aircraft resting on the seabed from the 1943–44 Allied bombing. The most famous is the Hakusan Maru, a 140-metre transport ship teeming with marine life.
• Rabaul Volcano Observatory: Overlooking the harbour, the observatory monitors the active Tavurvur and Vulcan volcanoes. Visitors can learn about the 1994 eruption that devastated Rabaul town and see the dramatic volcanic landscape up close.
• Japanese Barge Tunnels: Carved into the cliffs around the harbour, these tunnels sheltered Japanese landing craft during WWII. They are now accessible for exploration, offering a haunting glimpse into the war.
• Bitapaka War Cemetery: A serene, well-maintained cemetery honouring Allied soldiers who died in the region. It’s a poignant reminder of the Battle of Rabaul.
• Traditional Villages: Visit local communities such as Rakival or Kabanga to experience Melanesian culture, witness traditional dances, and see handicrafts like shell money and bilum bags.

Suggested Time to Spend

Allocate at least three to four days to fully experience Simpson Harbour. Two days are ideal for diving the wrecks and exploring the harbour by boat; a third day can be spent visiting the volcano observatory, the war tunnels, and a traditional village. If you’re a dedicated diver or history buff, extend to five days to explore more wrecks and hike Tavurvur volcano.

Nearby Areas Worth Combining

• Duke of York Islands: A short boat ride away, these idyllic islands provide white-sand beaches, snorkelling, and a peaceful escape from the harbour’s bustle.
• New Ireland’s East Coast: Drive north along the Boluminski Highway to explore plantation ruins, hot springs, and remote beaches like Kavieng’s.
