Aguas Termales de Logén, in the Arequipa region of Peru, offers sulfurous bicarbonate water at 40°C. The site is enjoyed in a natural open-air pool, suited to wild bathing.
Insider tip — Aguas Termales De Logen is situated near the Colca Canyon region of Arequipa department, one of the world's deepest canyons carved by the Rio Colca at roughly 3200 m elevation. The Andes here are highly volcanic, and the springs rise along fault lines associated with the nearby Sabancaya and Ampato volcanic complex. The dramatic canyon scenery — with condors soaring overhead — makes bathing here a geologically and visually unforgettable experience; combine the visit with a dawn condor-watching stop at Cruz del Condor.
