Rabaul Caldera

Rabaul Caldera is a dramatic volcanic crater on the island of New Britain, Papua New Guinea, offering a raw and unforgettable landscape shaped by powerful eruptions. The caldera, partially filled by Simpson Harbour, is surrounded by active volcanoes like Mount Tavurvur, which last erupted in 2014, dusting the area in ash. This is a place where the earth's power is palpable, and the resilient town of Rabaul, rebuilt after the 1994 eruption, tells a story of human endurance. For travellers with a taste for adventure and geology, Rabaul Caldera is a bucket-list destination that combines stark natural beauty with rich wartime history.

Highlights & What to See

• Mount Tavurvur – The most active volcano in the caldera; take a boat trip to see its steaming cone and feel the heat of the earth up close.
• Simpson Harbour – A stunning natural harbour within the caldera, dotted with volcanic islands and excellent for snorkelling or diving on coral reefs and WWII wrecks.
• Rabaul Town – Explore the rebuilt town with its colourful market, war relics, and the Rabaul Volcano Observatory for fascinating insights into volcanic monitoring.
