Aconcagua Provincial Park
Aconcagua, at 6,961 meters, is the highest mountain in the Americas. The provincial park protecting it is located about 180 kilometers west of Mendoza on Ruta Nacional 7 towards Chile, just past Puente del Inca and approximately 15 kilometers before the border. The drive there passes the Potrerillos reservoir and through the Andean village of Uspallata.Even without summit ambitions, a visit is worthwhile: A short circular trail leads to Laguna de Horcones with views of the massive south face; those with more time can hike in a day to the first base camp, Confluencia. For all trails, you need a permit, which you acquire in advance. The main season for trekking and ascents runs from mid-November to mid-March. Just before the park, a stop at Puente del Inca, a natural rock bridge over the river, is recommended.
