Coropuna at a Glance

About Coropuna

Coropuna is a massive stratovolcanic complex in southern Peru, located in the Arequipa Region. It is notable as one of the highest volcanic massifs in the country and forms a prominent part of the local Andean skyline.

The complex includes multiple summits and broad glaciated slopes; the highest point reaches roughly 6,425 metres above sea level. Climbers visit the mountain, and its glaciers have been the subject of glaciological research and monitoring.

Coropuna has held significance for local communities since pre-Columbian times and features archaeological evidence of human presence at high elevations. In recent decades the glacier extent has been studied in the context of regional climate change.

The mountain lies in the western cordillera of the southern Peruvian Andes within Arequipa region territory and is visible from surrounding valleys and highland communities.

  • Elevation: The mountain is one of Peru’s highest volcanic complexes, with its highest summit reaching approximately 6,425 metres above sea level.
  • Glaciation and Mountaineering: It is heavily glaciated in its upper reaches and is a destination for mountaineers and scientific study of Andean glaciation.

Tips for Visiting Coropuna

  • Plan your visit in the dry season (roughly May-September) for more stable weather and clearer summit views; the high Andes have a pronounced wet season that makes access and glacier travel riskier.
  • Acclimatize for several days in Arequipa or the Colca Valley before attempting high-altitude approaches-Coropuna's access and any climbing involve sustained elevation gain and glacier travel.
  • Arrange logistics with experienced local operators: access to Coropuna is remote and typically requires 4x4 transport, route knowledge and camping equipment, so hire a guide rather than attempting a self-supported approach.
When to Go

Best Time to Visit Coropuna

Attempt Coropuna during the dry season (May-September) when weather is most stable for high-elevation travel.

Dry season (best for climbing/trekking)
May-September · Below freezing at night to around 0-5°C (≤32-41°F) by day at high elevations
Clearer, drier weather and lower storm risk make this the preferred window for high-altitude approaches and climbs.
Wet season
October-April · Often below freezing at night; daytime temps vary but can be near or below 0°C at altitude
Warmer at lower elevations but more precipitation, snow and poorer conditions higher on the mountain-less reliable for summit attempts.
