The park protects the transition between the Chaco Serrano and the Yungas forest ecoregions.
It is a key habitat for the taruca, an endangered deer species endemic to the Andes.
The park preserves significant archaeological sites, including the Ciudacita, an Inca settlement situated at 4,400 meters above sea level.
Altitudes within the park range from approximately 800 meters to over 5,000 meters above sea level.
The Aconquija mountain range acts as a climatic barrier, trapping moisture and creating the dense cloud forests characteristic of the region.
It provides a sanctuary for the Andean condor, which utilizes the high mountain thermals for navigation.
The park was created in 2018 by expanding the existing Campo de los Alisos National Park.
Parque Nacional Aconquija protects a vital ecological corridor linking the high-altitude Andean peaks with the Yungas cloud forests of Tucumán. The park preserves endemic biodiversity, including the endangered taruca and diverse bird species like the Andean condor. Its terrain features steep mountain slopes, deep valleys, and high-altitude grasslands known as pampas. The area serves as a transition zone between distinct ecoregions, facilitating unique wildlife interactions. The park includes the former Campo de los Alisos National Park within its expanded boundaries. Visitors can explore various trails ranging from lowland forest paths to challenging mountain ascents. It is a critical site for ornithologists and hikers seeking untamed, rugged landscapes in northwestern Argentina.

Bring layers, as temperatures fluctuate significantly between the humid cloud forest base and the cold alpine heights.
Register at the ranger station before embarking on any long-distance mountain trails.
Carry all necessary water and supplies, as there are no facilities once you move away from the entrance area.
Do not attempt high-altitude mountain trails without proper trekking experience, specialized gear, and local park ranger clearance.
Access to high-altitude mountain sectors may be restricted during winter months due to heavy snow and severe weather conditions.
Practice leave-no-trace principles, remain on marked paths to avoid disturbing wildlife, and do not feed local animals.
