Termas del Callao

Termas del Callao serves the Villarrica area of the Chilean Araucanía, at the base of Villarrica volcano — one of South America's most persistently active volcanoes, whose 2,847-meter snow-capped cone harbors an open lava lake visible from the summit on clear days and whose 2015 major eruption, with spectacular nighttime lava fountains photographed from the nearby town of Pucón, demonstrated the extraordinary geological energy that simultaneously makes the surrounding Villarrica Lake one of Chile's most popular summer resort destinations and one of its most dangerous volcanic landscapes. The Mapuche people know the volcano as Rucapillán ('House of the Pillán spirit') and regard it with profound spiritual reverence, seeing in its fire and smoke the presence of ancestral spiritual forces that demand respect and maintain the boundary between the human and the supernatural world. The bicarbonate thermal waters of Termas del Callao, heated by the same geothermal system underlying Villarrica's active volcanic heart, invite guests to soak in mineral springs that carry the warmth of one of the Andes' most dramatic volcanic systems in a landscape where natural beauty and geological power are inseparable.
