Cerro Torre
Cerro Torre is a world-famous granite spire rising to 3,128 meters in the Southern Patagonian Icefield on the Argentina-Chile border. Renowned for vertical sheer granite walls topped by monstrous rime-ice mushrooms formed by relentless Pacific winds, it is widely considered one of mountaineering's supreme technical challenges.

Documented Climbing Routes (3)
Compressor Route (Southeast Ridge)
The Compressor Route along the Southeast Ridge of Cerro Torre is one of mountaineering history's most renowned and debated lines. Initiated in 1970 by Italian climber Cesare Maestri using an Atlas Copco gas-powered air compressor to install roughly 400 expansion bolts up blank headwalls, the route was completed to the true summit in January 1979 by American climbers Jim Bridwell and Steve Brewer in an audacious alpine-style push.
Southeast Ridge Free Line (Lama Route)
The Southeast Ridge Free Line on Cerro Torre is one of the crowning triumphs of modern free climbing. First envisioned and freed in January 2012 by Austrian prodigy David Lama, alongside Peter Ortner, the route free-climbs the sheer, exposed granite of the Southeast Ridge without using Cesare Maestri's artificial bolt ladders, establishing a pure line rated 5.13b (8a) up to the summit rime mushroom.
Cerro Torre West Face (Via dei Ragni)
The Via dei Ragni (Ragni Route) on the West Face of Cerro Torre is widely regarded as one of the world's most aesthetic, difficult, and prestigious mixed alpine ice climbs. Pioneered in January 1974 by Casimiro Ferrari, Daniele Chiappa, Mario Conti, and Pino Negri of the Ragni di Lecco, the route ascends 600 metres of vertical granite, sheer mixed gullies, and towering vertical rime-ice mushrooms (graded AI5+ M4). It represents the first undisputed, definitive route to the summit of Cerro Torre.
