Illimani South Ridge Normal Route
The South Ridge Normal Route of Nevado Illimani is the classic high-altitude line ascending the southern monarch of the Cordillera Real to 6,438 metres. First climbed in September 1898 by Sir William Martin Conway and Swiss guides Antoine Maquignaz and Jean-Antoine Pellissier, the route traverses hanging glaciers and the famous Nido de Cóndores aerie before conquering an exposed 50-degree knife-edge summit arête.

Tactical & Camp Notes
Starting from the village of Pinaya, climbers ascend steep shepherd paths to Puente Roto Base Camp at 4,500 metres. The route then scrambles over rocky scree and slabs to gain the dramatic Nido de Cóndores (Condor's Nest) high camp at 5,550 metres, perched on a narrow rocky spur between two immense glacier tongues. From the aerie, climbers rope up to negotiate a fractured lower glacier, weave past giant seracs, and surmount a steep 50-degree bergschrund wall. The final section follows a breathtaking knife-edge snow ridge with sheer drops into the Amazon basin, reaching Pico Sur at 6,438 metres.
