Aguas Termales de Sallihua, in the Puno region of Peru, offers sulfurous bicarbonate water at 40°C. It is enjoyed as wild bathing in a natural open-air pool on the high Andean plateau.
Insider tip — Aguas Termales De Sallihua lies very close to Hot Springs Poye in the Macusani plateau of Puno, sharing the same high-altitude volcanic geology at around 4400 m. The springs emerge from fractured ignimbrite flows and ash deposits left by the Macusani caldera system, producing sulfurous waters that stain the ground with yellow-orange mineral precipitates. The remoteness of the area means these springs remain almost entirely unknown to international tourism, making them a rare off-the-beaten-path geothermal discovery.
