Termas de Chillán, part of the Nevados de Chillán ski resort in the Ñuble Region of central Chile, is one of South America's most remarkable combined ski-and-spa destinations, where calcareous geothermal springs at the base of the active Chillán volcanic complex allow visitors to ski on volcanic slopes during the day and soak in thermal pools heated by magmatic activity at night. The naturally warm calcium-rich waters emerge at temperatures between 50°C and 80°C from vents in the volcanic terrain, channelled into outdoor pools that steam dramatically against the snow-covered Andean backdrop. The Nevados de Chillán ski area — with its extensive piste network, heli-skiing terrain, and dramatic volcanic landscape — combines with the thermal springs to create Chile's most distinctive mountain wellness and adventure destination.
Insider tip — Termas de Chillan sits at 1,800 m on the flanks of the active Nevados de Chillan volcanic complex, combining Andean ski infrastructure with geothermal pools fed by bicarbonate-rich spring water. In winter the juxtaposition of snow skiing and open-air hot pools at sub-zero temperatures is a unique Andean experience. Summer visitors enjoy hiking trails across the volcanic plateau with direct views of fumarole activity. The resort pools reach 36-38°C and remain operable year-round, though the ski lifts operate June through October only.
