Lanín Volcano, towering at 3,776 meters, is an iconic symmetrical stratovolcano that straddles the Chile-Argentina border. Its perfect conical shape and snow-capped summit make it one of the most photographed mountains in Patagonia. Sacred to the Mapuche people, Lanín means “rock that fell” or “dead” in Mapudungun, reflecting its dormant nature with no recorded historical eruptions.
This majestic peak is the centerpiece of Lanín National Park on the Argentine side and offers challenging multi-day climbing expeditions that require glacier travel and technical mountaineering skills. The surrounding area features pristine lakes, ancient monkey puzzle forests, and excellent hiking trails. The volcano’s prominence and isolation create dramatic weather conditions, requiring climbers to be well-prepared for rapidly changing alpine environments.
