Nahuel Huapi National Park: complete guide to plan your visit

Located in Northern Patagonia, Nahuel Huapi spans parts of the provinces of Rio Negro and Neuquen. With an official surface of about 717,261 hectares, it includes Andean ranges, deep lakes and forests that gradually transition into Patagonian steppe.

Environments and ecosystems

Around 60% of the park is covered by Andean Patagonian forests dominated by coihue, lenga and nire. Eastward the landscape opens into steppe with coiron grasses and hardy shrubs adapted to low rainfall and wind. At higher elevations, alpine vegetation becomes sparse and adapted to cold and exposure.

Climate and best time to visit

Temperate-cold climate with marked seasonality. Winters are humid with frequent snowfall and average temperatures between 2 and 4 C. Summers are drier, with averages between 14 and 16 C. Rainfall decreases from about 4000 mm per year in the Andean sector to roughly 600 mm in the steppe.

Flora and fauna

Forests include coihue, lenga and nire; in humid valleys you will also find maitenes, myrtles and ancient alerce stands. Fauna highlights include the endangered southern river otter (huillin), Andean condor, puma and huemul, as well as endemics like the Chalhuaco frog and colonial tuco-tuco.

History in brief

In 1903 Francisco P. Moreno donated lands that created the National Park of the South, the first in Latin America. In 1934 Nahuel Huapi National Park was formally established. It also hosted Argentina's first forest nursery, today an internationally recognized botanical garden.
