Baños Termales Larcay, in Peru's Apurímac Region, offer bicarbonate thermal water at 36°C with an alkaline pH of 8. Open-air bathing in an Andean setting suited to unwinding.
Insider tip — Larcay's thermal springs emerge in the Apurimac region near the headwaters of the Apurimac River, one of the Amazon's most distant sources, amid Andean highland terrain at over 3,000 meters. The bicarbonate waters surface in a deeply incised canyon carved by millennia of glacial and fluvial erosion, with terraced Inca-era agricultural remnants visible on the slopes above. The remoteness keeps visitor numbers low, rewarding those who make the journey with solitude and an authentic highland Andean experience. Local herders pass by with llama trains, a sight unchanged over centuries in this corner of Peru.
