Just when the ski season wraps up in the northern hemisphere, South America’s Andean mountains open for business. From June to October, incredible alpine conditions can be found in the world-class resorts of Argentina and Chile. Check out the deep powder of Las Leñas (Argentina) or the lofty heights of Chacaltaya (Bolivia) for a serious thrill.

Las Leñas, Argentina: This extraordinary resort has more runs than any other mountain in the Americas. Its relatively remote location, excellent snow, vibrant nightlife and small crowds make it a superb choice for serious downhill skiers.

Portillo, Chile: Arguably the best ski hill in Chile, the 17 runs of Portillo feature a little bit of everything. Natural attractions abound on site, such as Laguna de Inca, a stunning glacial lake.

Termas de Chillán, Chile: This nicely developed resort features South America’s longest run at eight miles (13kms). There are 30 downhill trails, 11 lifts and excellent slopeside facilities to ensure that all your needs are met.

Cerro Catedral, Argentina: Argentina’s largest ski resort sits along the eastern flanks of the Patagonia Andes. South America’s only gondola is here, along with an exciting après-ski scene, reliable snowfall and unbeatable views.

Chacaltaya, Bolivia: The planet’s highest ski resort tops out at 5,200m above sea level, and features excellent runs down the slopes of the Parinacota and Sajama volcanoes. The volcanic scenery is particularly magnificent and warrants a visit in itself.

El Colorado, Chile: Chile’s largest ski resort is just 24 miles (39kms) from Santiago, making it a very popular ski destination. It connects to the neighboring resorts of Valle Nevado and La Parvato, creating a truly massive skiing environment.

Chimborazo, Ecuador: Although its infrastructure is virtually nonexistent, ski hounds can find decent snow among the peaks of Cotopaxi, Antisana, Cayambe and Chimborazo. This is one ski destination where you’ll have to do most of the work.

Los Nevados, Colombia: There aren’t any ski resorts in Colombia but that doesn’t mean you can’t ski. Head to the volcanic region around Los Nevados for a heavy dose of off-the-grid adventure skiing.

Valle Nevado, Chile: This large ski resort has one of the best infrastructures in South America. Snowcat and heli-skiing companies provide one of the most extreme and adventurous ski experiences around, while modern spas will pamper those aches after the day is done.

Chapelco, Argentina: This small but decent ski resort near the town of San Martin de los Andes is one of the few places in South America with tree skiing. But don’t worry; most of the runs are your typical above treeline powder shoots.
