Lanín National Park Information

Lanín National Park

History of Lanín National Park

Lanín National Park was created on May 11, 1937 (Decree No. 105,433/37 confirmed by Law No. 13,895) to protect an important section of the Argentinian Patagonian wooded mountain range, specifically the north Andean-Patagonian forests that harbor endemic species such as the pehuén, raulí, and pellín oak. It received the Spanish name "Parque Nacional Lanín". These species are only found in a small area of the province, making the park an ecologically significant place.

The park takes its name from the impressive Lanín volcano, whose towering presence dominates the surrounding landscape. The word "Lanín" means "dead" in Mapudungun, the language of the Mapuche indigenous communities that have inhabited these lands since ancient times.

The relationship between the park authorities and the Mapuche communities is cordial and cooperative, with an agreement to work together to preserve the park and its valuable natural and cultural heritage. As part of this process, the park has returned lands to indigenous communities, recognizing the importance of this territory to their culture and way of life. This collaboration is an example of how conservation and respect for cultural diversity can coexist, promoting the preservation of the region’s natural environment and cultural heritage.

Ecological and Cultural Significance

This park is a valuable refuge for endemic species and is crucial for the conservation of Patagonian biodiversity. Additionally, the region holds a deep cultural significance for the Mapuche indigenous communities that have inhabited these lands for centuries.

Geographical Location

Geological Features of the National Park

The Lanín Park region is situated in a mountainous setting within the Andes mountain range, in the Patagonian Forest, Patagonian Steppe ecoregion. The terrain is characterized by steep slopes and elevations ranging from 900 to 1900 meters above sea level, except for the highest point, which is the Lanín volcano, situated on the border with Chile and reaching a height of 3776 meters. At its summit, a cap of permanent ice and snow can be observed.

The park’s landscape is dominated by glacial landforms, particularly erosional types such as lake basins and U-shaped valleys. Evidence of volcanic activity can also be found, including basalt flows from the Lanín volcano, the Achen Niyen scoria cone, and the Lahuen-Có hot springs and Lake Queñi. Glacial erosional landforms predominate in the northern and central areas of the park. The Tromen Lake basin displays glacial erosion and sedimentation phenomena. Around Lake Huechulafquen, lateral moraines can be observed, formations in the landscape caused by the accumulation of materials carried by glaciers. To the west of Lake Currhué lies the Huanquihue volcano, showing evidence of its more recent volcanic activity in the form of a scoria cone.

Climate in Lanín

The climate of Lanín National Park is cold and humid, typical of the Patagonian Andes. During winter, average temperatures are around 4°C, while in summer they reach 20°C.

Precipitation is more frequent in winter and comes from the moist winds blowing from the South Pacific. Areas close to the mountains receive a significant amount of rain due to the region’s orography. This creates humid forests on slopes and valleys, while towards the east, rainfall decreases, transitioning to a steppe environment. Average annual precipitation is around 1800 mm, but it varies between the eastern and western parts of the park. In mountainous areas, figures can exceed 4000 mm per year. Frequent snowfalls occur during the months of May to October. In higher areas above 1600 meters, the climate is more severe, with very low temperatures and precipitation in the form of snow.

Biodiversity of Lanín

Iconic Park Fauna

The Andean condor (Vultur gryphus) and the araucaria or pehuén (Araucaria araucana) are two prominent symbols of Lanín National Park.

The Andean condor is a mighty bird with a wingspan of approximately 3 meters. It is known for its ability to soar in the air using thermal currents. Its plumage is mostly black, but it has a collar and a white area on the back of its wings. Males have a reddish crest on their heads devoid of feathers, while females lack a crest. Juveniles are brown and lack the white markings.

On the other hand, the araucaria or pehuén is a coniferous tree that can grow up to 50 meters in height. Its growth is extremely slow, and some specimens can live up to 1000 years. Older trees have branches that open high up, giving them a characteristic umbrella-like shape. Araucaria leaves are tough and have a spine at the tip. The seeds, known as pine nuts or piñones, are edible and have high nutritional value.

These emblematic species, the Andean condor and the araucaria, represent the unique biodiversity and natural beauty of the ecosystem present in the area.

Local Flora

The park hosts notable botanical diversity that plays a crucial role in regulating water in northern Patagonia. Among the present plants, several endemic herbs and shrubs can be found, as well as forests of pehuén, pellín oak, and raulí.

The mighty elevations of the mountain range exhibit snow-capped peaks and slopes covered in dense Nothofagus forests. In lower altitude areas like Hua Hum, the lush Valdivian temperate rainforest extends from the west, further enriching the park’s biodiversity.

Park Fauna

The park also boasts a rich diversity of fauna, with a total of 233 species of native vertebrates. Among mammals, species such as the puma, foxes, and the monito del monte, a marsupial, can be found. In terms of birds, notable species include the Andean tinamou, Andean condor, red-backed hawk, and the Austral negrito, among others.

The presence of these species underscores the park’s significance as a habitat for wildlife and the conservation of biodiversity in the region. Visitors to Lanín National Park have the opportunity to observe and enjoy the fascinating fauna that inhabits this natural environment.

The Lanín Volcano

Geological History

The Lanín Volcano, reaching 3,776 meters above sea level, is an inactive stratovolcano and one of the most iconic in the Patagonian Andes. Its presence dominates the park’s landscape and the entire region, with the snow-covered peak visible from afar. Its most recent eruptive events occurred thousands of years ago, leaving a snowy summit that is now an impressive sight for all visitors.

Ascent to the Volcano

Ascending Lanín is a popular yet challenging activity. Adequate preparation and the accompaniment of authorized guides are required. From the summit, the views of the surrounding lakes and forests are simply breathtaking.

Before embarking on the ascent of Volcán Lanín within the park, certain general requirements must be fulfilled. It is mandatory to register at the corresponding Section, either at Río Turbio for the northern face or Puerto Canoas for the southern face. During registration, participants’ identity details, place of residence or origin, planned activity, itinerary, and estimated duration of stay in the park must be provided.

The staff in charge will conduct an inspection of the necessary equipment, which can be rented in Junín de los Andes or San Martín de los Andes. Additionally, the required technical and physical preparation for the ascent will be evaluated. If all requirements are met, an ascent permit will be granted, along with the necessary information to carry out the journey.

Regarding equipment and clothing, it is mandatory to follow the established regulations. For ascending via the normal route, quality trekking boots, a mountain-appropriate coat, synthetic base layers, pants and overpants, gloves or mittens, a wool or synthetic hat, sunglasses or goggles with UV protection, gaiters, crampons, a UIAA-approved ice axe or poles, personal first aid kit, UV-filtered sunscreen, insulating pad, sleeping bag, locking carabiners, slings or cords, flashlight with spare batteries, whistle, and communication equipment with spare batteries are required.

For ascending via the southern face, in addition, a climbing helmet, climbing harness or seat harness, plastic or double boots instead of trekking boots, two technical ice axes instead of one ice axe and poles, safety and non-locking carabiners, ice screws and snow stakes, tubular slings and cords are required. If ascending in a group, a climbing rope of 50 meters and 9 mm diameter (or 30 meters and 9 mm diameter for the northern face) is required for every four people, as well as an additional heater for every four people.

Other requirements include having knowledge and experience in ice travel techniques, and for beginners, hiring the services of a mountain guide authorized by the National Parks Administration. It’s important to attempt the summit only in favorable physical and weather conditions and to inform the Park Ranger upon return.

The Lanín Volcano has two distinct seasons. The summer season runs from October 1st to May 31st of the following year, while the winter season spans from June 1st to September 30th of the same year.

Legends of Lanín Volcano

According to legend, Pillán, the God of evil, lived on the summit of Lanín Volcano and did not allow anyone to approach it. When the Huanquimil tribe attempted to reach the peak while chasing guanacos, a storm was unleashed, and the volcano began to spew lava, smoke, fiery flames, and ashes. The terrified population consulted the tribe’s sorcerer to learn how to appease Pillán’s wrath. The sorcerer informed them that they had to sacrifice Huilefún, the youngest daughter of the chief, and that Quechuán, the bravest youth of the tribe, had to throw her into the volcano.

Quechuán took Huilefún near the summit and left her alone. At that moment, a condor approached and grabbed her with its talons, throwing her into the crater. Huilefún’s sacrifice succeeded in permanently calming Pillán’s wrath. Since then, Lanín Volcano remains dormant but with its fires hidden beneath its white dome.

Even today, the Mapuche community considers Lanín Volcano a sacred place and refrains from making ascents out of respect for its spiritual significance. This legend illustrates how traditional beliefs and myths have left a cultural mark on the communities’ perception and relationship with the volcano and its surroundings.

Lanín Volcano and the Mapuche People

The Lanín Volcano holds significant importance for the Mapuche community, as it serves as an icon of identification and is considered a sacred site. At the base of the northern face, the annual celebration of the rewe takes place, which is a ritual of nature sanctification. This ceremony occurs in a space called rewe, which must be an open area allowing a view towards the east, where "Nguenechén," the Mapuche god, resides.

Starting from 2008, the ceremony is conducted at the foot of the volcano, where prayers are offered to seek various favors. The authorities of Lanín National Park promote respect for the spiritual and emblematic value that the volcano holds for the Mapuche people. It has been established that these values must be considered when making management decisions related to the volcano.

In this regard, regulations stipulate that any person crossing pasture areas of residents and/or indigenous communities, whether accompanied by authorized mountain guides or not, should exhibit respectful behavior towards them. Furthermore, authorities have restricted ascent to the volcano during the ceremony (ascent is only allowed via the southern face). However, the Mapuche people desire that access to the volcano be prohibited on any of the routes during these days.
