The Lago Puelo National Park (Spanish : Parque Nacional Lago Puelo) is a national park of Argentina, located in the northwest of the province of Chubut, in the Patagonia region of South America. It has an area of 276.74 square kilometres (68,380 acres). It was created to protect its scenic landscape and the Valdivian flora to augment that of the nearby Los Alerces National Park. Originally an annex to Los Alerces, it was declared a National Park and independent reserve in 1971.
The protected area is named after the Puelo Lake, and belongs to the Patagonic forest and steppes and High Andes eco-regions.
The mountainous zone where the park lies was modified by the action of glaciers, which created many rivers and lakes, including Puelo Lake the namesake of the park. The rivers of the region have high levels of glacier sediment (silt), which gives Puelo Lake its blue color.
The climate is cold and wet, although more temperate than other parks in the Patagonian region. [1] Mean temperatures range from 5 °C (41.0 °F) in winter to 17 °C (62.6 °F) in summer. [1] Mean annual precipitation is around 1,400 mm (55 in), most of it being concentrated between May and August. [1] Occasionally, snowfall can occur during the coldest months. [1]
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.
The 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 and the puyén grande, and foreign species of trout.
The first settlers of the region were hunter-gatherers who lived in the steppe and employed stone tools to hunt guanacos. There are cave paintings within the park, apparently showing representations of paths into the forest. Nowadays Mapuche communities live in the eastern part of the park.
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and Argentina. It is part of the Neotropical realm. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common.
Fitzroya is a monotypic genus in the cypress family. The single living species, Fitzroya cupressoides, is a tall, long-lived conifer native to the Andes mountains and coastal regions of southern Chile, and only to the Argentine Andes, where it is an important member of the Valdivian temperate forests. Common names include alerce, lahuén, and Patagonian cypress. The genus was named in honour of Robert FitzRoy.
Los Glaciares National Park is a federal protected area in Santa Cruz Province, Argentina.
Los Arrayanes National Park is a national park of Argentina with an area of 17.53 square kilometres (6.77 sq mi). It covers the Quetrihué Peninsula on the shore of the Nahuel Huapi Lake in the province of Neuquén, 3 km (1.9 mi) from Villa la Angostura.
Los Alerces National Park is located in the Andes in Chubut Province in the Patagonian region of Argentina. Its western boundary coincides with the Chilean border. Successive glaciations have molded the landscape in the region creating spectacular features such as moraines, glacial cirques and clear-water lakes. The vegetation is dominated by dense temperate forests, which give way to alpine meadows higher up under the rocky Andean peaks. A highly distinctive and emblematic feature is its alerce forest; the globally threatened alerce tree is the second longest living tree species in the world. The alerce forests in the park are in an excellent state of conservation. The property is vital for the protection of some of the last portions of continuous Patagonian Forest in an almost pristine state and is the habitat for a number of endemic and threatened species of flora and fauna.
Calilegua National Park is a federally protected area in Jujuy Province, Argentina. It was established on July 19, 1979, and is also the largest protected area in Argentina dedicated to conserving subtropical evergreen mountain rainforests known as Southern Andean Yungas. These Yungas, are transitional zones between the Andean highlands and the eastern forests.
Aconquija National Park, formerly known as Campo de los Alisos National Park, is a federal protected area in Tucumán Province, Argentina. Established on 9 August 1995, it houses a representative sample of the Southern Andean Yungas montane forest biodiversity in good state of conservation.

The El Rey National Park is a national park of Argentina, located in the Anta Department, province of Salta, in the Argentine Northwest, 80 km from the provincial capital. It has an area of 441.62 km2.
Lanín National Park is a national park of Argentina, located in the Neuquén Province, with forests of diverse tree varieties, mainly Fagaceae and conifers such as the lenga and the Araucaria, many species of which are not found elsewhere in Argentina.
The Predelta National Park is a national park of Argentina, located in south-west of the province of Entre Ríos, 6 km south from Diamante, in the Argentine Mesopotamia, at the beginning of the Paraná River Delta. The park was created on 13 January 1992 under the Law Nº 24.063, with an area 24.58 square kilometres to protect a sample of the Upper Delta of the Paraná, which belongs to the Paraná Delta and Islands Ecoregion. The Predelta is the area where the sediments of the Paraná start forming islands, while the river itself splits into several major arms and many smaller watercourses.
Alerce Andino National Park is located in the Andes, in Los Lagos Region of Chile. This national park covers about 393 km2. It is bounded by the Reloncaví Estuary on its east and south sides, and by the Reloncaví Sound to the west. To its north lies Chapo Lake.
Alerce Costero National Park is a protected wild area in the Cordillera Pelada about 137 km from Valdivia and 49 km from La Unión. Fitzroya trees grow inside the protected area and give the area its name, with Alerce Costero translating as Coastal Fitzroya. The Natural Monument has a total area of 137 hectares.
Perito Moreno National Park is a national park in Argentina. It is located in the western region of Santa Cruz Province on the border with Chile. It has an area of 126,830 hectares of mountains and valleys at a height of 900 metres above sea level.
Hiking in Chile is characterized by a wide range of environments and climates for hikers, which largely results from Chile's unusual, ribbon-like shape, which is 4,300 kilometres long and on average 175 kilometres wide. These range from the world's driest desert, the Atacama, in the north, through a Mediterranean climate in the center, to the glaciers, fjords and lakes of Patagonia in the south.
The Sierra de las Quijadas National Park is a national park located in the northwestern part of the Argentine province of San Luis. It was established on December 10, 1991, to protect the natural features, representative of the Semiarid Chaco and the High Monte ecoregions.
Nahuel Huapi National Park is the oldest national park in Argentina, established in 1922 as Parque Nacional de Sud and reconfiguered 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 km2 (2,720 sq mi), or nearly 2 million acres. Its landscapes represent the north Patagonian Andean Zone consisting of three types, namely, the Altoandino, the Andino-Patagónico and the Patagonian steppe. It also represents small parts of the Valdivian Rainforest.
Yendegaia National Park is in Tierra del Fuego in the Magallanes y la Antártica Chilena Region of Chile and contains 150,612 ha of mountainous terrain and Valdivian temperate rain forest. It borders the Alberto de Agostini National Park and Tierra del Fuego National Park.
Lake Menéndez is a large lake in Chubut Province, Argentina. Lake Menéndez is in the chain of lakes in the Futaleufú River system of Argentina which via Yelcho Lake and the Yelcho River flows into the Pacific Ocean in Chile. Located in the Andes, Lake Menendez is Y-shaped, of glacial origin, and occupies two narrow valleys between glaciated peaks. The lake is in the Los Alerces National Park. There are no roads or other developments near the lake. Travel is by boat or foot. Lake Menéndez is noted for the extensive Alerce (Fitzroya) forests near the tips of its two arms.
