Address: Huaraz Province, Ancash, Peru

Vallunaraju (also spelled Wallunaraju) is a snow-capped mountain in the Peruvian Andes, rising to about 5,686 metres and located in the Cordillera Blanca southwest of Ranrapalca and Ocshapalca. Its name likely comes from Ancash Quechua words referring to cutting and snow-covered mountains. The peak is one of many glaciated summits that form the dramatic skyline around the Huaraz area.

The mountain sits in the high, glaciated terrain popular with climbers and trekkers based in Huaraz and visiting the Cordillera Blanca. Approaches involve high-alpine valleys and snow or ice travel on the upper slopes. Conditions can be exposed and changeable, so visitors usually combine Vallunaraju with acclimatization and guided glacier travel in the region.

  • Summit panorama: From the upper slopes or summit you get sweeping views of neighbouring peaks such as Ranrapalca, Ocshapalca and the broader Cordillera Blanca skyline.
  • Glaciated faces: The mountain’s snow and ice slopes and small glaciers illustrate the tropical high-mountain glaciation of the range.
  • Approach valleys: The high valleys and moraines below the glaciers offer stark, high-Andes landscapes and classic mountain trekking terrain.
  • Nearby high peaks: Close views of higher massifs in the Cordillera Blanca put Vallunaraju in context as part of one of Peru’s most striking alpine areas.

Getting There & Around

How to Get to Vallunaraju#

The main base town for visits is Huaraz, a regional hub for treks and climbs in the Cordillera Blanca; most visitors travel to Huaraz from Lima by overnight bus or domestic flight plus road transfer. From Huaraz arrange transport by taxi, colectivo or tour operator to the trailheads and mountain villages that give access to Vallunaraju.

The last stretch to the mountain is on high mountain roads and then footpaths; glacier travel is required for the upper slopes, so hire a local guide and appropriate equipment. Much of the Cordillera Blanca falls under protected management - check rules and any park procedures with local authorities.

Tips for Visiting Vallunaraju#

  • Spend at least a couple of days in Huaraz to acclimatize before attempting high-altitude approaches or climbs.
  • Hire a certified local mountain guide and glacier-aware team for any travel onto snow and ice.
  • Weather and visibility change quickly at elevation; carry layered clothing, sun protection and a waterproof shell.
  • Respect local regulations and any protected-area requirements; ask locally about permits or restricted zones.
  • Be prepared for crevasse and avalanche hazard in wet or unstable conditions and avoid solo glacier travel.
