Termas Pucón Indómito, in Pucón, Chilean Araucanía, offers sulfurous water around 43°C. Indoor and outdoor baths, a sauna and massages make it a thermal stop at the foot of the Villarrica volcano.
Insider tip — Termas Pucon Indomito sits in the volcanic zone just west of Villarrica Volcano, one of Chile's most active peaks, whose persistent eruptions enrich local groundwater with sulfurous compounds. The resort concept emphasizes adventure tourism, combining thermal pool relaxation with trekking and kayaking in the surrounding Lake District. Waters reach approximately 43°C at source before being modulated across multiple cascading pools. Pucon itself is a major outdoor-adventure hub, and visiting in shoulder season (April-May or September-October) avoids the summer crowds.
