Kolombangara Hot Springs are situated on Kolombangara Island in the Western Province of the Solomon Islands, a near-perfectly circular volcanic cone rising 1,770 meters from the sea in one of the Pacific's most photogenic island silhouettes, its caldera rim perpetually wreathed in cloud forest and its slopes descending through primary rainforest to the mangrove-fringed coral lagoons below. Kolombangara was the site of significant World War II activity in the Solomons Campaign, with the Battle of Kolombangara (July 1943) fought in the surrounding waters and the island used as a Japanese stronghold whose 12,000 troops successfully evacuated in August 1943 in one of the war's most skillfully executed withdrawals. The island today is largely uninhabited, its primary forest protected by a forestry concession that has maintained the integrity of one of the Solomon Islands' largest remaining tracts of native lowland and montane rainforest, sheltering endemic bird species and exceptional biodiversity. The volcanic hot springs here draw on Kolombangara's active geothermal system, providing mineral bathing in a setting of wild Pacific island beauty and WWII historical resonance.

Insider tip — Kolombangara is a perfectly conical extinct volcano rising 1,770 m from the Solomon Sea, its cloud forest summit hiding sulfurous hot springs that bubble along stream beds on the island's lower flanks. The springs are reached by canoe from Gizo town followed by a jungle trail through primary rainforest where hornbills and endemic parrots are common. Water runs at a vivid 42°C with a distinct sulfur scent against cool forest air. Local guides from Vona Vona Lagoon villages know the best pool locations and can arrange overnight treks.
