Verano in Lanín National Park

Verano unlocks Lanín Parque Nacional at its best — trek the iconic Volcán Lanín, explore ancient araucaria forests, swim in pristine Andean lakes, and experience Mapuche culture surrounded by the Lake District's most dramatic volcanic scenery de diciembre a febrero.

Lanín Parque Nacional is one of Argentina's most spectacular protected areas, stretching 379,000 hectares along the Andes in Neuquén province. Dominated by the perfect volcanic cone of Volcán Lanín (3,776m), the park encompasses pristine lakes, dense Valdivian bosque, ancient araucaria (monkey puzzle) groves, and Mapuche indigenous communities — all within the northern Lake District.

Verano from diciembre a febrero is the prime season for exploring Lanín. Snow recedes from all but the highest peaks, opening hundreds of kilometers of senderismo trails. Temperatures reach 22-26°C in the valleys, lakes warm to swimmable temperatura, and the iconic volcán trek becomes accessible for mountaineers. The araucaria forests — living fossils dating back to the age of dinosaurs — stand in their full glory with fresh green growth.

The park's lakes are its jewels. Lago Huechulafquen, the largest, stretches 25km at the base of the volcán with organized camping, beaches, and boat excursions. Lago Paimún, Lago Tromen, and Lago Lácar each offer distinct landscapes and activities. Anglers find world-class trucha pesca in the park's rivers, while kayakers explore pristine shorelines backed by bosque and peaks.

What sets Lanín apart from other Patagonian parks is the living Mapuche culture within its boundaries. Several communities maintain their traditions, welcoming visitors to learn about their ancestral relationship with the land, forests, and the araucaria tree (pehuén), whose seeds have sustained Mapuche people for millennia.

The park is accessed from San Martín de los Andes (south) and Junín de los Andes (east). A auto de alquiler is essential for reaching the park's scattered access points and making the most of the vast territory.
