Introduction to Lago Puelo National Park

Lago Puelo National Park

Geographical Location

Located in the Chubut Province in southern Argentina, Lago Puelo National Park covers an area of over 27,674 hectares in the Valdivian Forest ecoregion. It borders Chile to the west and is situated 30 km from the city of El Bolsón. It can be geographically pinpointed with coordinates: 42°11′00″S 71°41′00″W / -42.183333333333, -71.683333333333.

National Park Background

Before the creation of Lago Puelo National Park, measures were taken to protect and preserve the region. In 1937, President Agustín Pedro Justo issued Decree No. 105,433, which established national reserves intended for national parks in four territories of Patagonia, including the Los Alerces national reserve in the National Territory of Chubut and its annex located approximately 115 km north at Lake Puelo. According to Article 2 of this decree, the boundaries of these reserves were established, and a portion of lot 8, the southern half of lot 7, lot 13, the western half of lot 14, the northwestern league of lot 17, and the northern half of lot 18, fraction A, were designated as an annex to Los Alerces National Park.

Subsequently, in 1945, Decree Law No. 9,504, under the presidency of Edelmiro Julián Farrell, transformed the national reserve into Los Alerces National Park, including the Puelo Annex. This was established in Article 7, which declared the national parks, including Los Alerces, with the boundaries established in Decree No. 105,433 and modifications made by previous decrees.

It is worth noting that, since the decree law was issued by a de facto government, it was ratified as Law No. 13,895 on September 30, 1949. These measures laid the foundation for the creation of the national park, thus preserving its natural beauty and biodiversity.

History and Park Creation

The park was created on October 11, 1971 under the Spanish name "Parque Nacional Lago Puelo" with the objective of protecting one of the most beautiful and representative areas of the Andean-Patagonian forests and the Puelo Lake basin.

The history of the Lago Puelo National Park region has deep and diverse roots. The name "Puelo" comes from the Mapuche word "puelco," which means "water from the east." This beautiful area received its name from Chilean Mapuche communities, who referred to this place as both the river and the lake. The Puelo River originates in Argentine territory and flows to the Pacific Ocean, crossing the Cordillera and flowing into the Reloncaví estuary.

In 1621, Spanish conqueror Juan Fernández sailed around Chiloé Island and navigated up the Puelo River in search of the legendary "City of the Caesars." Although he didn’t find the mythical city, which was believed to be inhabited by survivors of Don Pedro Sarmiento de Gamboa’s expedition and filled with incredible riches, he was the first man to reach the region and establish contact with the Poya indigenous people. However, these indigenous people were later exterminated by the Mapuche invasion that dominated Patagonia, although they didn’t settle in this area due to their nomadic lifestyle.

After Fernández’s visit, the region had no colonizers or Creoles until 1884 when Chilean Pedro "Motoco" Cárdenas settled in the area he called "Valle Nuevo." Cárdenas was the first white man to inhabit what he believed was a pastoral valley with good grasslands in Chilean territory.

In 1885, the expedition to the Cordillera of the 29 riflemen from Chubut took place, organized by Governor Luis Jorge Fontana. These riflemen, mostly Welsh volunteers, explored the territory and discovered the fertile valley of October 16. This area was disputed between Argentina and Chile until the arbitration award of 1902, when the Welsh settlers who were already in the place unanimously proclaimed Argentine sovereignty over the region.

In 1928, Remigio Nogues, a teacher sent by the governor of Chubut, proposed the creation of a development commission. On April 2 of the same year, the commission was formed, mostly consisting of teachers, and covered the valleys of Lago Puelo, Cerro Radal, Las Golondrinas, El Hoyo de Epuyén, El Turbio, and Lago Esperanza.

The first wave of immigrants in the area was that of Chilean livestock herders, who brought Mapuche laborers that later had Argentine descendants. The children of these first pioneers regularized land tenure. Later, Lebanese immigrants arrived, crossing the Patagonian plateau, followed by a group of Ukrainians who engaged in agriculture, bringing new techniques for working the land, especially in hop cultivation. Subsequently, Argentines and other Europeans settled. By 1920, 95% of the region’s population was foreign, and teachers played a crucial role in teaching the language and Argentine history to promote unity in the region.

In 1936, an exploratory commission was conducted that toured the area with the aim of identifying new places to be incorporated into protected areas of national parks.

Finally, in 1971, the small settlement of Lago Puelo became Lago Puelo National Park. After the major forest fire in 1987, a group of residents began organizing the National Forest and Environment Festival, with the aim of raising awareness about the protection of native forests. This annual celebration includes various activities such as folk festivals, sports competitions, and talks about forest conservation, featuring national artists and the selection of a queen.
