Without a doubt the best place for mountaineering in Peru is the spectacular Cordillera Blanca which is truly a climber’s paradise. There are plenty of peaks over 5,000m and incredible 33 peaks over 6,000m including Huascaran with its 6,768masl is Peru’s highest peak.
Climbing technical mountains or over 6000 m mountains such as Alpamayo, Quitaraju, Tocllaraju, Artesonraju, Chopicallqui , Huascaran is best done during the dry season (June to September) with optimum conditions usually in July but 5000 m mountains or less such as Pisco, Vallunaraju, Urus, and Ishinca can be done throughout the year.
Acclimatization is essential so allow between 4 days and 1 week before starting the ascent depending on the height and difficultly of the mountain.
The peaks of Ishinca (5,534m) and Pisco (5,752m) are suitable for inexperienced climbers. Alpamayo (5,957m), generally regarded as Peru’s most beautiful mountain, is suitable for intermediate climbers, while Huascaran (6,768m) can prove quite a challenge not due to its technical but also for its altitude.
