Aconcagua Provincial Park

Aconcagua Provincial Park is a protected area in Mendoza Province, Argentina, containing Cerro Aconcagua, the highest mountain in the Americas at about 6,960 metres. The park protects high Andean terrain, glaciated slopes and the valleys leading to the mountain.

The central attraction is Aconcagua itself, which draws mountaineers and trekkers from around the world. Common visitor activities include multi-day approaches from the Horcones valley, acclimatization and base-camp stays at Plaza de Mulas (about 4,370 m), and technical climbs on routes such as the Polish Glacier; many trips start from the provincial road network that connects to Route 7.

Park management administers access, issues permits for ascent and high camps, and enforces seasonal restrictions. Facilities are concentrated at established trailheads and base camps rather than throughout the high-mountain zone.

The park lies in the high Andes of western Mendoza Province close to the Argentina-Chile border; the city of Mendoza is roughly 100-120 km to the east, with road access to the Horcones valley via Uspallata and Route 7.

• Peak elevation: Rises to about 6,960 metres, the highest peak in the Americas and the highest mountain outside Asia.
• Common routes and base camp: Most summit attempts follow the Normal Route from Horcones, with Plaza de Mulas at roughly 4,370 m as the main base camp.
• Access and season: Permits and seasonal regulations are required for high-altitude trekking and summit attempts; the main climbing season is the Southern Hemisphere summer, roughly December through February.
