The Ferrari Route is the best-known and most documented line on Cerro Torre, ascending the west face to the summit. It is a highly technical alpine climb combining steep ice, mixed climbing, and exposed aid or free climbing depending on conditions. The route is notorious for rapidly changing Patagonian weather, strong winds, and severe objective hazards. Conditions on the upper mountain can include verglas, rime, and unstable ice formations. It is a serious, committing ascent typically attempted by very experienced alpinists. The route is historically significant and is one of the classic objectives on the peak.
