Pucón in the context of Mapudungun

Lanín is an ice-clad, cone-shaped stratovolcano on the border of Argentina and Chile. It forms part of two national parks: Lanín in Argentina and Villarrica in Chile. As a part of the flag and anthem of the Argentine province of Neuquén, it serves as a symbol for the region. Although the date of its last eruption is not known, it is estimated to have occurred within the last 10,000 years. Following the 1906 Valparaíso earthquake a local newspaper reported the volcano to have erupted, but a work published in 1917 by Karl Sapper disputed this.

The ascent is regulated by the management of Argentine National Parks and the Argentine National Gendarmerie and is technically relatively simple but has a much higher level of exposure than the neighbouring volcanoes. The nearest towns, usually employed as a base for climbers, are Pucón in Chile and Junín de los Andes in Argentina.

The Chilean Lake District is a zone in Southern Chile defined by its many lakes in the Andean foothills. The term is primarily used in tourism literature and advertising, in Chile Zona Sur is preferred as a geographical concept. The Chilean Lake District includes the cities of Temuco, Villarrica, Pucón, Valdivia, Osorno, Entre Lagos (Puyehue), Puerto Octay, Frutillar, Puerto Varas and Puerto Montt.

All lakes drain ultimately to the Pacific Ocean. In the north to Toltén River collects the water of Villarrica, Caburgua and Colico. South of these lakes lie the Seven Lakes whose waters reach the Pacific through Valdivia River. Bueno River drains the water of Ranco, Maihue, Puyehue and Rupanco lakes. Llanquihue Lake is drained to the Pacific by Maullín River and Petrohué River does the same for Todos los Santos Lake.
