Nahuel Huapi National Park (Spanish:Parque Nacional Nahuel Huapi) is the oldest national park in Argentina, established in 1934. It surrounds Nahuel Huapi Lake in the foothills of the Patagonian Andes. The largest of the national parks in the region, it has an area of 7,050 km (2,720 sq mi), or nearly 2 million acres. Its landscapes represent the north Patagonian Andean Zone consisting of three types, namely, the Altoandino (with perpetual snow above an altitude of 1,600 metres (5,200 ft)), the Andino-Patagónico (in the lower reaches of the hills) and the Patagonian steppe. It also represents small parts of the Valdivian Rainforest.
