The Huayhuash Mountains (pronounced why-wash) are a small chain to the south of the Cordillera Blanca. They were made famous in 1988 by Joe Simpson’s book Touching the Void, turned into a movie in 2003.
These mountains are not part of Huascarán National Park and are not part of the Cordillera Blanca either. Only a small part is in the Áncash province, with most of it in the Lima province.
Nevertheless most people use Huaraz as the jumping off point for Huayhuash.
Treks 4–12 days
Most people start in the town of Pacllón for a trek of 4 - 12 days. The various trails are between 45-180 km (28-112 miles). There are routes that take you in a loop around the mountains, though some go to summit the glacial peaks.
The Casa de Guías in Huaraz is the best place to get information on how to find a guide or to organize your own trek through Huayhuash.
Cordillera Huayhuash Reserved Zone charges s/10-s/50 per night, depending on which campground you’re in.
