Termas del Plomo

Termas del Plomo, located in the Santiago Metropolitan Region at approximately 2,500 metres altitude in the Andean foothills east of the Chilean capital, are siliceous springs emerging from the glacially carved Plomo River valley — a high-altitude tributary of the Mapocho River system. The springs are set in a dramatic mountain landscape accessible by a long drive through the Cajón del Maipo canyon, one of Santiago's most beloved natural escapes, making them a popular destination for urban Santiaguinos seeking wild thermal bathing in the Andes. The siliceous mineral composition of Plomo's waters reflects the volcanic and plutonic geology of the principal Andean Cordillera, where ancient magmatic activity has left behind a mosaic of geothermal resources across the region.
