Perito Moreno National Park Information

Perito Moreno National Park

History and Establishment of the Park

Created on May 11, 1937, through Decree No. 105,433/37, the Perito Moreno National Park was later ratified by Law No. 13,895, designating its name in Spanish as "Parque Nacional Perito Moreno". This park is one of Argentina’s oldest and most prestigious, although not as well-known as others. Nevertheless, its historical and ecological importance is immense.

The presidential decree established the creation of national reserves to transform them into national parks, and Perito Moreno was one of the territories designated within the National Territory of Santa Cruz. Through various decrees, the park’s boundaries were modified in its eastern and northern fronts.

Subsequently, on April 28, 1945, decree law No. 9504 transformed the national reserve into a national park, later being ratified as law by Law No. 13,895, enacted on September 30, 1949. This law consolidated the boundaries of the national parks, including Perito Moreno National Park.

It is important to mention that, on October 11, 1971, law No. 19,292, driven by Alejandro Agustín Lanusse, modified and ordered the boundaries of the national parks, including the Perito Francisco P. Moreno National Park and Reserve. These measures aim to protect and preserve the region’s natural wealth, ensuring its long-term conservation.

Geographical Location and Access

Located in the central-west of the Santa Cruz province in Argentina, in the Río Chico department, bordering Chile, this park covers an area of 115,000 hectares. To reach it, you can travel by road or plane to the city of El Calafate, and then take a bus or car to the park. It can be geographically located by the coordinates 47°48′41″S 72°15′02″W.

Meaning of the Name: Who was Perito Moreno?

The park is named after Francisco Pascasio Moreno, known as Perito Moreno, a renowned Argentine explorer and scientist who played a crucial role in demarcating the border between Argentina and Chile.

Size and Topographical Characteristics

The park extends over a vast territory of mountains, lakes, rivers, and forests, with astonishing geological diversity in an area of 142,120 hectares. From the high peaks to the tranquil lake shores, every corner offers a different landscape to explore.


The climate of Perito Moreno National Park is generally cold and humid, with mild summers and cold winters. The best time to visit is from November to April when temperatures are more pleasant, and most of the trails are open.

As you move from east to west, the annual rainfall can vary significantly, ranging from 400 to 3,000 mm. The influence of strong, persistent, and icy westerly winds is notable in the region. During winter, temperatures can drop to -25°C, while in summer, the average temperature hovers around 15°C. However, it’s important to note that even during summer, snow is possible, so being prepared for different weather scenarios is necessary.

Characterized by being a rugged area within the Andean-Patagonian region of Argentina. The ideal season to visit is from late spring to early autumn when temperatures are more moderate, and weather conditions are more favorable for enjoying outdoor activities.

Biodiversity: Flora and Fauna in Perito Moreno

Main Ecosystems

The park harbors a wide variety of ecosystems, from subantarctic forests to grasslands and wetlands. This diversity of habitats contributes to its rich biodiversity, which includes several species of flora and fauna, some of which are endemic to the region, belonging to the ecoregions: Patagonian Forest and Patagonian Steppe.

Iconic Species of the Park

The emblem of Perito Moreno National Park is the huemul (Hippocamelus bisulcus). Despite its robust body, this incredible deer moves with great skill through the rugged mountains of the region. Males have antlers that renew annually and often live solitarily, in pairs, or in small family groups. The huemul is a species declared a National Natural Monument, emphasizing its significance and the need for its protection.

Another iconic symbol of the park is the lenga (Nothofagus pumilio), a tree widely distributed in the Patagonian forests. Depending on conditions, lenga trees can reach heights of approximately 30 meters in sheltered areas, while in higher and exposed zones, they grow as low shrubs. During autumn, before shedding, their leaves turn shades of red and ochre, creating a stunning visual spectacle in the park’s landscape.

Distinctive Flora

The park is home to a diverse array of plant species adapted to its cold and humid climate. The diverse flora adapts to the various present ecosystems.

In the forests, the dominant species is the lenga tree, which varies in form depending on altitude. Alongside the lenga, there’s the guindo tree, whose northern distribution limit is in this area. Often, the guindo tree is associated with canelo and notro trees, creating a beautiful landscape.

In wetlands, the ñire tree is a species capable of adapting to various environments. However, its presence in wetlands is particularly important, as these ecosystems are fragile and of high conservation value.

In steppe areas, the vegetation appears as low, bushy shrubs adapted to conditions of low humidity, low temperatures, frost, and strong winds. Some of these shrubs are cushion-shaped, others are thorny, and there are species with tiny or even absent leaves. Xerophytic grasses, like coirones, can also be found, along with communities adapted to specific soil features, such as meadows, salt flats, and river terraces.

In the high areas of the Andean mountain range, the flora complements the vast diversity of species present in the park. These areas house species adapted to extreme altitude and climate conditions, adding even more beauty and variety to the flora of Perito Moreno National Park.

Region’s Fauna

Perito Moreno National Park serves as a refuge for a multitude of animal species. Thanks to the presence of Andean forests, sub-Andean grasslands, lakes, lagoons, and wet meadows, many species of animals find their home here. Among these, the Magellanic tuco-tuco and the orange chinchillón stand out as endemics of Southern Patagonia.

In these environments, you can also encounter red and gray foxes, mountain cats, grassland cats, lesser ferrets, Patagonian skunks, and Patagonian pichis.

The park’s primary herbivores include guanacos and huemuls, with the latter being considered a provincial Natural Monument due to its endangered status. These animals play a crucial role in structuring the park’s plant ecosystems and are natural prey for pumas.

If you’re fortunate enough to spot a huemul, it’s crucial to inform park personnel, as this contributes valuable information about the species in the protected area.

Regarding birds, it’s possible to observe the choique or lesser rhea, the gray gull, and the condor. A species of amphibian, the Nansen lake frog, can also be found, along with puyenes and peladillas in the lakes.
