Nahuel Huapi National Park is based around imposing Andean mountains and a scenic lake of the same name. It is the oldest national park in Argentina, having been established in 1934. The park is also the largest in the region, with an area of 2,720 square miles (7,050 square kilometers). Take part in many outdoor activities, from rafting and kayaking to paragliding and mountain biking.
Take your family or friends on a scenic trek through the forests and valleys of the park. The quickest trails include the Cerro Llao Llao, which should take only 2 or 3 hours to reach the summit. It offers splendid views of Nahuel Huapi Lake. For shorter walks, climb Cerro Campanario or visit Los Duendes Waterfall. Experienced hikers may prefer a route that covers the entire park from Pampa Linda to Colonia Suiza, which takes around 5 days.
