About Aconquija National Park

Aconquija National Park protects the high Andean landscapes of the Sierra del Aconquija range, offering unique temperate forests, diverse wildlife, and opportunities for hiking and nature observation.

Wilderness Landscape & Natural Heritage

Aconquija National Park is located in the Tucumán province of northern Argentina, encompassing part of the eastern slopes of the Sierra del Aconquija mountains. The park covers a range of altitudes, from foothill valleys to peaks surpassing 4,000 meters (13,120 feet), featuring dramatic topography that supports diverse habitats including cloud forests, high Andean grasslands, and Polylepis woodlands. Its varied ecosystems provide refuge for many endemic and threatened species, including the endangered Andean mountain cat and the taruca deer. The park was established to conserve these fragile environments and the hydrological systems that originate in the area, supplying water to downstream agriculture and communities. Visitors to Aconquija National Park can explore extensive hiking trails that wind through dense forests of lenga and queñoa trees, witness panoramic views of the surrounding Andean peaks, and enjoy birdwatching opportunities with species like the Andean condor and the Andean flicker. The park includes several glacial lakes and streams, which add to its scenic appeal and habitat diversity. Infrastructure within the park remains relatively undeveloped, emphasizing low-impact, backcountry experiences for visitors. Local indigenous cultures historically inhabited these lands, and their presence is reflected in archaeological sites and traditional knowledge related to the park’s natural resources. Aconquija National Park is an important destination for ecotourists and those interested in the natural and cultural richness of the southern Andes.
