Termas de Mamiña

Termas de Mamiña, located in Chile's Tarapacá Region in the Atacama highlands east of Iquique at approximately 2,730 metres altitude, are radon-bearing and chloride-rich springs emerging in a dramatic quebrada (ravine) oasis that has sustained human habitation since pre-Columbian times. The springs' distinctive radon content has long made them a pilgrimage destination within a long thermal bathing tradition, and the town is locally known by an evocative nickname tied to its waters. The town's adobe architecture, pre-Columbian agricultural terraces, and Aymara cultural heritage give Mamiña a cultural depth that makes it one of Chile's most historically layered thermal oases.
