Casablanca, Stratovolcano in Los Lagos Region, Chile

Casablanca is a Holocene stratovolcano in the Andes of Los Lagos Region, Chile, about 90 km east of Osorno. Its cone rises between Lakes Puyehue and Rupanco, and the Antillanca ski resort occupies its western slope.

After the last glacial period ended, multiple scoria cones formed around the volcano's basin shaping its current structure. This volcanic activity marked an important transition in the geological development of the Southern Volcanic Zone.

On the western slope of Casablanca sits the Antillanca ski centre, inside Puyehue National Park, with 512 hectares of skiable terrain for skiing and snowboarding. It is the main winter sports base of Los Lagos Region, about 90 km from Osorno.

Access to the slopes is via the Antillanca ski centre road, which serves 512 hectares of skiable terrain on the western flank. The volcano lies between Lakes Puyehue and Rupanco inside Puyehue National Park, about 90 km from Osorno. Check road and snow conditions before setting out, since the access lies at elevation.

Casablanca has no recorded historical eruptions; its lavas range from basalt to andesite, and several scoria cones formed after the last ice age. The volcano lies between Lakes Puyehue and Rupanco, and its western flank holds the Antillanca ski centre, with 512 hectares of skiable terrain.
