Baños termales de Collpa, in the Junín region of Peru, fill their indoor pools with bicarbonate thermal water at 37°C. Sauna and massage round out this Andean facility's offering.
Insider tip — Banos Termales de Collpa emerges in the central Peruvian Andes in Junin department at approximately 3200 m, where the high-altitude Andean plateau geology produces mild bicarbonate thermal springs. The setting is austere highland puna, with ichu grass stretching to snowcapped peaks on clear days. The springs lie along trekking routes connecting highland communities; budget extra acclimatization time if arriving directly from sea level before soaking.
