Villarrica National Park is in the Andes Mountains, within the La Araucanía and Los Ríos regions of Chile, near the city of Pucón. The main feature of the park is a line of three volcanoes that stretch across the Andean range: Villarrica, Quetrupillán, and Lanín. Other mountains in the park include Quinquilil volcano, which is 2,050 meters (6,726 feet) high and also called Colmillo del Diablo, and Cerro Las Peinetas, which is located on the border between Argentina and Chile. The park's height ranges from 600 meters (1,969 feet) to 3,776 meters (12,388 feet) at Lanín Volcano.

A drainage divide between the Toltén River and Valdivia River basins runs through the park. This divide also marks the boundary between Cautín Province and Valdivia Province.

Part of the park is included in the Bosques Templados Lluviosos de los Andes Australes Biosphere Reserve.

Flora and fauna

The park helps protect the Valdivian temperate rainforest habitat. Roble (Nothofagus obliqua) and Raulí (Nothofagus alpina) trees grow at lower elevations. Coihues live in the wettest areas. At higher elevations, trees are mostly Araucarias (Araucaria araucana).

The park's forests provide homes for animals such as pumas, chillas, culpeos, pudúes, coypus, Harris's hawks, lesser grisons, Molina's hog-nosed skunks, and the rare monitos del monte.

Hot springs

The Termas Geométricas hot springs system is found in a deep valley within the park forest. It includes 60 hot springs and cold waterfalls that visitors can explore using a series of winding wooden walkways made of planks.
