Hornopirén, Stratovolcano in Los Lagos Region, Chile

Hornopirén is a 1,572-metre stratovolcano in Hualaihué commune, Los Lagos Region, Chile, mainly covered by forest with a glacier at its summit. It lies 10 km north of the town of Hornopirén, immediately south of Lake Cabrera and Yate Volcano, and on the Liquiñe-Ofqui Fault.

Hornopirén is a stratovolcano in Hualaihué commune, Los Lagos Region, lying on the Liquiñe-Ofqui Fault. It is said to have erupted in 1835, but no details of that event are known and there is no confirmed historical record of eruptions. Its name comes from Mapudungun pirén, "snow oven"; it was formerly called Quechucaví.

The name combines Spanish 'horno' (oven) with Mapudungun 'pirén' (snow), showing how two languages meet in this place. This blend of words reflects how indigenous peoples and Spanish settlers both shaped the region over centuries.

The summit is forested and holds a glacier, so the climb is not a marked park trail; the nearest access is from the town of Hornopirén, 10 km south. The volcano lies on the Liquiñe-Ofqui Fault, and the Cabrera lake and Yates volcano sit immediately north. Plan for the wet, changeable weather of the Los Lagos Region.

The volcano lies on the Liquiñe-Ofqui fault, and its summit holds a glacier, while the slopes are mostly forested. Its last eruptive activity is attributed to 1835, but no details of that eruption are known and there is no confirmed historical record of eruptions.
