Hornopirén National Park, situated in southern Chile's Los Lagos region, is a pristine wilderness in the Chilean Andes. It forms part of the Bosques Templados Lluviosos de los Andes Australes Biosphere Reserve and showcases rich biodiversity and spectacular natural features.

Hornopirén National Park: A Haven of Rugged Mountains and Ancient Forests

Hornopirén National Park, located in the Palena Province of Chile's Los Lagos region, is a pristine wilderness within the Chilean Andes. The park, covering 482 square kilometers (186 square miles) of rugged mountains and untouched Valdivian temperate rainforests, derives its name from the Mapundungún term "Snow Oven," a nod to the majestic Hornopirén Volcano. Though not within park boundaries, this volcano epitomizes the dramatic landscapes that define the region. Hornopirén National Park is part of the Bosques Templados Lluviosos de los Andes Australes Biosphere Reserve, showcasing rich biodiversity and spectacular natural features.

Geography and Natural Features

Glacier-carved mountains, active volcanoes, and lush rainforests characterize Hornopirén National Park. The Yate Volcano, standing at 2,187 meters (7,175 feet) above sea level, and the Hornopirén Volcano, at 1,572 meters (5,157 feet), dominate the park's skyline. These volcanic giants, along with extensive glaciers covering an area of 30 square kilometers (12 square miles), create a rugged and awe-inspiring landscape.

The park's lakes are notable for their striking blue and green hues resulting from glacial till suspended in the water. The three main bodies of water are Pinto Concha Lake, the most visited attraction in the park; Inexplorado Lake, part of the Blanco River basin; and Cabrera Lake. These lakes, along with six main rivers, including the significant Negro River, form a vital part of the park's ecosystem, surrounded by ancient Alerce (larch) forests.

Flora and Fauna

Hornopirén National Park boasts a rich tapestry of flora dominated by the ancient Alerce trees. Covering about 97.41 square kilometers (38 square miles) and comprising approximately 35 percent of the park's vegetation, these trees are the second oldest species on Earth. Other notable tree species in the park include Coigüe, Mañío, Luma, Tepu, and Tineo, with Lenga trees prevalent at higher altitudes.

The park supports diverse wildlife, with about 25 mammal species. These include native species such as the cougar, kodkod, lesser grison, chilla fox, pudú, and the endangered Chilean huemul, as well as exotic species like the American mink and coypu. The park is home to 18 threatened species, underscoring its importance as a conservation area.

Birdwatchers can delight in the park's avian diversity, with 123 species recorded. Highlights include the Chucao Tapaculo, Hued Hued, Black Woodpecker, Kingfisher, and Quetru Volador. The varied habitats within the park, from dense forests to open water bodies, provide ideal conditions for these bird species to thrive.

Route of Parks

Hornopirén National Park is an integral part of Chile's scenic 2,800-kilometer (1,700-mile) "Route of Parks," which stretches from Puerto Montt in the north to Cape Horn in the south. This ambitious conservation initiative spans 17 national parks, protecting over 11.8 million hectares (28 million acres) and covering one-third of Chile. The Route of Parks aims to preserve the country's natural heritage while promoting sustainable tourism and local development.

Conservation and Significance

Hornopirén National Park's inclusion in the Bosques Templados Lluviosos de los Andes Australes Biosphere Reserve highlights its ecological significance. The park's diverse ecosystems provide critical habitats for numerous plant and animal species, from ancient forests to glacier-fed lakes and rivers. Conservation efforts focus on protecting these unique environments from threats such as illegal logging, poaching, and climate change.

Collaborative efforts between government agencies, non-profit organizations, and local communities are essential to safeguard the park's natural beauty and biodiversity. These initiatives aim to balance conservation with sustainable use, ensuring that future generations can continue to enjoy and benefit from this remarkable natural area.


Hornopirén National Park is a testament to Chile's commitment to preserving its natural heritage.
