Main image

Ampato is a high volcanic mountain in Peru’s Arequipa region, part of the Western Cordillera of the Andes. The volcano rises to an elevation of about 6,288 metres and forms part of a cluster of high Andean volcanoes near the city of Arequipa.

The mountain is notable both for its alpine climbing routes and for archaeological significance: in 1995 archaeologists discovered a well-preserved Inca child sacrifice mummy on the summit, one of the best-known high-altitude Inca finds. The peak is approached by technical alpine routes that require acclimatization and glacier travel skills.

Ampato sits among neighboring volcanoes including Misti and Sabancaya, within the high Andean zone west of the Altiplano. Access for expeditions is typically from base locations in the Arequipa region and involves multi-day approaches at altitude.

  • Elevation: Mountain summit reaches about 6,288 metres above sea level, making it one of the higher volcanic peaks in southern Peru.
  • Inca summit find: Site of a major archaeological discovery in 1995 when a well-preserved Inca child sacrifice mummy was recovered from the summit area during scientific fieldwork.

Tips for Visiting Ampato #

  • Climb Ampato in the dry season (roughly May-September) when routes are more reliable and access roads are less likely to be closed by weather.
  • Acclimatise thoroughly in Arequipa for several days before attempting Ampato - even experienced climbers are affected by altitude above 5,000 m and summit attempts usually require multiple days.
  • Hire a licensed mountain guide and outfitter in Arequipa; Ampato involves glacier travel and technical snow slopes, and local operators handle logistics, permits and basecamp support.
