On the southwest slope of Volcán Casablanca (1990m), Antillanca is a popular beginner/intermediate ski resort. It's just 18km up a volcanic gravel road from Aguas Calientes. It has a friendly small-resort ambience, but is not challenging for more advanced skiers. The road up to the resort twists and turns through scenic areas and past glassy lakes.
During the no-snow months Antillanca is rather drab, but the resort’s saving grace rests with its trails, especially the walk or drive (per vehicle CH$10,000) to Volcán Casablanca's Cráter Rayhuén, and Cumbre Mirador, where you can drink in a spectacular view of the surrounding mountain range that includes four volcanoes and the region's highest point, Cerro Tronador (3470m), on the border with Argentina.
