Relaxing — deep, immediate muscle release.
Rich in active gases or metals — a strong mineral character.
Soft water — natural, classic buoyancy.
Tanna Hot Springs are located on Tanna Island in the Tafea Province of Vanuatu, an island of extraordinary geological and cultural interest dominated by Mount Yasur — one of the world's most accessible active volcanoes, whose constant eruption with visible lava bombs, glowing crater glow, and the thunderous booming of regular explosions can be observed from just meters away on a viewing platform at its rim, making it the most viscerally spectacular and approachable volcanic experience available to travelers anywhere on Earth. Tanna is also the center of the John Frum cargo cult movement, one of the most famous and persistently active millenarian religious movements to emerge from the colonial era's disruption of Melanesian cultures, whose adherents still perform ceremonies and maintain faith in the eventual return of John Frum and the material abundance his arrival will bring. The hot springs here draw on the geothermal energy of Yasur's volcanic system, providing bicarbonate mineral bathing in an island landscape where living volcanism, ancient animist custom, and the continuing vitality of one of anthropology's most studied cargo cult traditions create one of the Pacific's most culturally extraordinary settings.
