At 6962m – or 6959m according to some maps – CERRO ACONCAGUA is the highest peak in both the western and southern hemispheres, or outside the Himalayas. Its glacier-garlanded summit dominates the Parque Provincial Aconcagua, even though it is encircled by several other mountains that exceed 5000m: cerros Almacenes, Catedral, Cuerno, Cúpula, Ameghino, Güssfeldt, Dedos, México, Mirador, Fitzgerald, La Mano, Santa María and Tolosa, some of which are easier to climb than others, and many of which obscure views of the great summit from most points around. The five glaciers that hang around its faces like icy veils are Horcones Superior, Horcones Inferior, Güssfeldt, Las Vacas and Los Polacos.
Although climbing Aconcagua is technically less demanding than climbing many lower-altitude peaks, it is still a challenge to be taken seriously. Fitness, patience and acclimatization are key, and, unless you’re fairly experienced at high-altitude treks, you shouldn’t even consider going up; despite what the agencies may tell you, both independent climbers and people climbing as part of organized treks often end up turning back.
Aconcagua may be the highest Andean mountain, but for many mountain purists, it lacks the morphological beauty of Cerro Mercedario to the north or Volcán Tupungato to the south; it’s also not as difficult a climb to the summit as some of the other Andean peaks. Nevertheless, ever since it was conquered by the Italian–Swiss mountaineer Mathias Zurbriggen in 1897 – after it had been identified by German climber Paul Güssfeldt in 1883 – Aconcagua has been one of the top destinations in the world for expeditions or solo climbs. In 1934, a Polish team of climbers made it to the top via the Los Polacos glacier now named after them; in 1953, the southwest ridge was the route successfully taken by a local group of mountaineers; and in 1954, a French team that had successfully conquered Cerro Fitz Roy made the first ascent of Aconcagua up the south face, the most challenging of all – Plaza Francia, one of the main base camps, is named after them. In recent years, Aconcagua has become a major attraction for less experienced mountaineers, and of the seven thousand-odd people who try to reach the summit every year, about half make it.
