Top 10 Volcanoes in Chile
Chile has more active volcanoes than any country outside the Pacific tropics: a 4,000-kilometre spine of cones running from the Atacama deserts to Patagonia. Many are accessible, several are still erupting, and a few rank among the most beautiful mountains in the world.
1. Villarrica
The classic Andean fire-mountain above the lake town of Pucón. A near-perfect snow cone with a permanent lava lake; the standard guided climb is one of the most popular adventure objectives in the country.
2. Osorno
A near-twin of Mount Fuji on the shore of Lake Llanquihue — symmetrical, glaciated, and on every Patagonia itinerary. Mostly quiet, but classed as active.
3. Calbuco
Just south of Osorno, Calbuco erupted spectacularly in 2015 with a column visible across Patagonia. The volcano is back to quiet status, but the fresh tephra coating still shows.
4. Llaima
Conguillío National Park's centrepiece — a fast-erupting volcano in the Araucaria forest belt, with hikes through monkey-puzzle trees and lava fields.
5. Lascar
The most active volcano of the high Atacama, near San Pedro. A short, high-altitude scramble climbs to its smoking summit; the views over the Salar de Atacama are otherworldly.
6. Ojos del Salado
The highest volcano on Earth at 6,893 m and the second-highest peak in the Americas. A serious mountaineering objective on the Argentina–Chile border, attempted by acclimatised climbers each austral summer.
7. Parinacota
A perfectly conical volcano in the far north, shared with Bolivia, in Lauca National Park above the Altiplano. Climbed and photographed beside Lake Chungará.
8. Chaitén
The 2008 eruption rebuilt a quiet volcano in a few weeks and required the evacuation of an entire town. The dome-rebuilt summit is reachable on a half-day climb from a still partly-rebuilt Chaitén.
9. Cerro Hudson
A remote Patagonian volcano whose 1991 eruption deposited ash across the Southern Hemisphere. Not a tourist objective, but a defining presence on the southern map.
10. Puyehue–Cordón Caulle
A long fissure system whose 2011 eruption disrupted air travel across the Southern Hemisphere. The lava field is now an active recovery laboratory inside Puyehue National Park.
How Chile's volcanoes line up
The volcanoes follow the trace of the subducting Nazca Plate. Three broad zones split them: the Atacama high volcanoes (Lascar, Ojos del Salado); the Lakes District ring (Osorno, Villarrica, Llaima); and the Patagonian volcanoes (Chaitén, Hudson). Each is a separate trip.
Climbing and access
SERNAGEOMIN runs Chile's monitoring and publishes a public alert page. Villarrica is the standard guided climb; Ojos del Salado is for acclimatised mountaineers only. National park access is well organised but altitude and weather are real obstacles even on "easy" objectives.
