Aguas Termales de Yauli, in Peru's Junín region, provides bicarbonate water at 37°C with a mildly alkaline pH of 8. Indoor pools, massage and a sauna offer a relaxing break at altitude.
Insider tip — Aguas Termales De Yauli lies near the mining district of La Oroya in Junin, at roughly 3700 m — one of the highest thermal spring sites in Peru. The springs emerge from Andean basement rocks in a valley shaped by glacial action, surrounded by high puna and rocky moraines. Despite the industrial character of the surrounding region, the thermal pools remain a cherished gathering spot for local highland communities who value the warm mineral-rich waters.
