Balneario de Pojpoquella, in Peru's Puno region, taps a sulfurous spring with water reaching around 42°C. Indoor pools, massage and a sauna round out this small thermal facility set on the altiplano.
Insider tip — Balneario de Pojpoquella lies at the edge of the Altiplano near Lake Titicaca in the Puno region, where volcanic geology produces sulfurous thermal waters at altitude. The stark high-plateau landscape surrounding the baths is dramatic, with views stretching toward distant snow-capped peaks. Basic changing facilities are typically available; visitors should carry cash as card payments are rarely accepted in remote Andean balnearios. Soak for no more than 20 minutes at a time given the altitude and heat combination.
