Aguas Termales de Obrajes is a sulfurous hot spring site in the South American Andes, where naturally heated volcanic mineral waters emerge in a setting associated with the obrajes — colonial-era workshops or mills that gave their name to this Andean location. The spring produces naturally heated sulfurous mineral waters from the active volcanic geology of the Andean cordillera, and local communities have used its waters for bathing within a long thermal tradition across generations of settlement in this high-altitude Andean landscape. Visitors experience sulfurous mineral bathing in a setting shaped by the layered colonial and pre-Columbian heritage of the Andean highlands, where the waters of volcanic springs have been recognized and valued since long before European contact.
Insider tip — Aguas Termales de Obrajes sits at Andean altitude near Cochabamba, Bolivia (noted under Chile in the database but coordinates place it in Bolivian territory), where sulfurous thermal waters emerge at 38°C from fault-controlled vents. The high-altitude setting above 2,500 meters means the surrounding air is crisp and cool, making the warm sulfurous soak particularly invigorating. Local communities have used these waters for generations to treat skin and respiratory conditions. The terraced volcanic landscape surrounding the site offers dramatic Andean panoramas.
