Chachani

Chachani is a stratovolcano located approximately 20 kilometers (12 miles) northwest of the city of Arequipa in southern Peru. It is part of the Western Cordillera of the Andes.

Chachani is characterized by its multiple summits, with the highest point reaching an elevation of approximately 6,057 meters (19,872 feet) above sea level. It is considered an extinct volcano, showing no signs of recent volcanic activity. The mountain's slopes are largely arid and rocky, with sparse vegetation.

Due to its proximity to Arequipa and relatively straightforward access (compared to other high Andean peaks), Chachani is a popular destination for mountaineering and high-altitude trekking. Acclimatization is crucial for climbers attempting to reach the summit.

The mountain's name is believed to originate from indigenous Quechua words, though the exact meaning is debated. Chachani provides a significant source of water for Arequipa through glacial melt and runoff.
