Lanín National Park is a 413,000 ha area located in the southwest of Neuquén province, in the Argentine Patagonia, bordering Chile to the West and Nahuel Huapí National Park to the South. It was created in 1937 to protect and preserve an important area of Andean-Patagonic Forests, especially the Monkey-puzzle trees (Araucaria araucana), the Raulí (Nothofagus nervosa) and the Roble beech (Nothofagus obliqual), which in Argentina are exclusive of this National Park.
It is the third largest National Park in Argentina after Nahuel Huapí National Park and Los Glaciares National Park in Santa Cruz province.
Full of glacial lakes (more than 20), mountains and rivers the park offers wonderful landscapes with excellent examples of three different ecoregions: the High-Andean Steppe, the Patagonic Steppe and the Andean-Patagonic Forest. The weather is mild a humid, with warm summers that allow enjoying the lakes and riverside, plenty of rain during spring and autumn and frequent snow and temperatures below zero in winter. The park takes its name from the highest peak, by far, of the area, the Lanín (meaning “Dead Rock” in the native mapuche language) volcano, an ice-clad cone-shaped extinct stratovolcano of 3,776 m which borders with Chile. Being a huge cone located in a relatively low altitude area, in clear days the volcano is visible from very far way, becoming a short of an icon of the region, to the point of being one of the symbols of the Neuquén province.
Lanín National Park provides plenty of touristic attractions especially for those searching for nature, great landscapes and adventure. Many visitors come to climb Lanín volcano, which is relatively easy and can be done in two days, sleeping in one of the mountain huts along the way. Other good climbs that can be done within the day are peaks Chivo (2,064 m,) Colorado (1,774 m) and Mallo (1,941 m), all of them with spectacular views at the top and along the way. Apart from the climbs there are plenty of softer trekking options such as the Malleo circuit, the Saltillo waterfall, the Corinas lagoons, and the Queñi termas springs, among many others. Those are beautiful walks across the Andean Patagonic forest or the Valdivian Rain Forest that allow all visitors including children to enjoy a great day of pure nature. There are multiple camp sites within the park, most of them on the lakes shores; some are just free camping areas with no services while some others are more organized and have basic services.
