This geothermal spring in Chile is fed by the naturally heated discharge water from nearby public thermal baths, channelled into an outdoor pool that maintains its geothermally elevated temperature and mineral character. Such secondary thermal pools — fed by the outflow from main bathing facilities — are common features of Chilean thermal resort complexes, where the naturally mineral-rich geothermal water is used sequentially across a series of pools of decreasing temperature before being returned to the natural watercourse. The pool provides a warm, mineralised bathing experience that benefits from the same geothermal spring source as the main facility.
Insider tip — This unusual site in Chile's Libertador region channels warm wastewater from public thermal baths back into a secondary soaking area, maintaining a gentle 37 °C that is ideal for relaxation without overstimulation. The thermal source originates from geothermal activity beneath the central Chilean Andes foothills. The setting is semi-urban, surrounded by vineyards and farmland characteristic of the Colchagua Valley. Water sandals are advisable as the pool floor can be uneven.
