Introducing Parque Provincial Aconcagua
North of RN7, nearly hugging the Chilean border, Parque Provincial Aconcagua protects 710 sq km of the wild high country surrounding the western hemisphere’s highest summit, 6962m Cerro Aconcagua. Passing motorists (and those who can time their buses correctly) can stop to enjoy the view of the peak from Laguna Los Horcones, a 2km walk from the parking lot just north of the highway.
During trekking season there are rangers stationed at Laguna Los Horcones; the junction to Plaza Francia, about 5km north of Los Horcones; at Plaza de Mulas on the main route to the peak; at Refugio Las Leñas, on the Polish Glacier Route up the Río de las Vacas to the east; and at Plaza Argentina, the last major camping area along the Polish Glacier Route.
Only highly experienced climbers should consider climbing Aconcagua without the relative safety of an organized tour.
