Chopicalqui Southwest Ridge
The Southwest Ridge of Chopicalqui is one of the most aesthetic and popular high-altitude ridge climbs in the Cordillera Blanca. First scaled in August 1932 by Erwin Schneider, Philipp Borchers, and Hermann Hoerlin, the line rises along a soaring glaciated crest from the col above Quebrada Llanganuco.

Tactical & Camp Notes
Departing from the Llanganuco-Chopicalqui curve on the road beneath Portachuelo de Llanganuco, climbers trek through quenual forest to Base Camp at 4,200 metres, then ascend rough talus and lateral moraines to Moraine Camp at 4,900 metres. Roping up for the glacier, the route weaves through crevasses to High Camp at 5,600 metres on the broad Southwest Col. On summit day, climbers follow the winding glaciated ridge, negotiating airy 45-50 degree snow slopes, bypassing gaping crevasses, and scaling a steep 55-degree bergschrund crux before stepping onto the razor-sharp summit cornices.
