Rabaul Hot Springs PNG

Rabaul, on the Gazelle Peninsula of East New Britain Province in Papua New Guinea, sits inside one of the world's most spectacular calderas, a partially submerged volcanic complex where multiple active cones including Tavurvur volcano ring the former harbour, which was devastated by volcanic eruptions in 1994 and partially rebuilt nearby. The Rabaul Hot Springs draw on sulfurous geothermal waters from this extraordinarily active volcanic system, emerging from fumaroles and vents on the caldera rim and offering a rare and dramatic volcanic thermal experience in one of the Pacific's most geologically restless environments. The Rabaul Volcano Observatory, the World War II Japanese submarine base tunnels still accessible in the caldera walls, and the Kokopo war museum documenting the intense Pacific Campaign fighting in this strategic harbour make Rabaul a destination of exceptional geological and historical depth in the Bismarck Archipelago.
