The Nahuel Huapi Nationalpark, established in 1934 and named after the Nahuel Huapi Lake, is the oldest national park in Argentina. The park covers an area of 7'050 square kilometres in the foothills of the Patagonian Andes.
The area is known as the Argentine Lake District, as there are many lakes in the park, including Nahuel Huapi, Mascardi, Gutiérrez, Traful, Guillelmo and Perito Moreno Lakes. Cerro Catedral is a 2'388 metres high peak within the park and an important ski resort. Cerro Tronador (3'491 m) on the Chilean border is the highest mountain in the park.
