Aguas Termales Upis lies near Ocongate in the Cusco region of Peru, beneath the Andean peaks. Its bicarbonate water emerges around 35°C, feeding an open-air pool popular with hikers looking for a wild soak at altitude.
Insider tip — Upis thermal springs sit at 4,400 metres in the shadow of Ausangate (6,384 m), the sacred Apu mountain of the Cusco highlands. Trekkers completing the Ausangate circuit soak here under snow-capped peaks — one of the world's most dramatic hot spring settings.
