Pirihueico, Chile - Termas Geometricas, in the native forest of the Villarrica National Park, is a wooden boardwalk that follows a mountain stream where hot springs water fills 17 slate-covered pools. Bathers often gather around a communal fire pit here. There are indoor and outdoor hot springs pools at Termas de Peumayen. Termas Huife, a hotel, spa, restaurant, and coffee shop just east of Pucon, has three warm mineral-water pools.
