Cerro Aconcagua

Aconcagua is the highest mountain in both the western and southern hemispheres, standing at 6,961 metres in the Andes of Mendoza province near the Chilean border. Its southern face is one of the largest near-vertical rock walls at extreme altitude in the world. While a summit attempt requires mountaineering permits and a minimum of three weeks, the approach trek to Plaza de Mulas base camp passes through dramatic high-desert landscapes and is accessible to fit hikers without technical climbing equipment.
