The Lago Puelo National Park is located in the province of Chubut, in the Patagonia Forest ecoregion of Argentina. Having been created as an annex to the Los Alerces National Park, in 1971 it became an independent 27,674 ha (68,383 acre) area. Along with four other national parks, it comprises a part of the Andino Norpatagónica Biosphere Reserve.
The characteristics of this natural reserve are unique in Patagonia. Due to its height above sea level (only 200 m or some 650 ft), its geographical environment and its geologic formation, the park is home to many endemic flora species, and exhibits beautiful scenery and exceptional weather.
Mean temperatures range from 5 °C (41.0 °F) in winter to 17 °C (62.6 °F) in summer. Mean annual precipitation is around 1,400 mm (55 in), most of it being concentrated between May to August. Occasionally, snowfall can occur during the coldest months.
The mountainous zone where the park lies was modified by the action of glaciers, which created many rivers and lakes, including the one (Puelo Lake) that gives the park its name. The rivers of the region show high levels of glacier sediment (silt), which gives Puelo Lake its blue color. The lake empties into the Pacific Ocean via the Puelo River, impressively framed by Mount Tres Picos and Mount Vanguardia.
Some of the flora of the park belongs to the Valdivian rain forests (avellano, tique, lingue, ulmo). It also includes the ciprés de la cordillera, the coihue, the lenga, the radal, and the arrayán. The rosa mosqueta is an exotic plant.
he fauna includes the pudú, the huemul, the red fox, the cougar, and the coipo. Among birds we find the huala, the pato vapor volador, the bandurria, the pitío and the zorzal patagónico. The lake features native fish such as the perca, the peladilla, the puyén grande, and foreign species of trout.
