Arapahoe Basin is not an incorporated Colorado town. It is a mountain destination and ski area on U.S. Highway 6 in Summit County, near Loveland Pass and the Continental Divide. MKT Colorado includes it in the A–Z guide because A-Basin has a distinct identity, history and visitor culture of its own.
Founded in 1946 by Larry Jump and Sandy Schauffler, both former ski racers and World War II 10th Mountain Division veterans, A-Basin opened with a single rope tow. It is the oldest ski area in Summit County and in 2026 celebrates 80 years on the Divide.
Steep skiing, high elevation and a fiercely distinctive culture. The East Wall, Pallavicini, The Steep Gullies, The Beavers, Montezuma Bowl, spring skiing and the famous base-area “Beach” have made A-Basin one of Colorado’s most recognizable ski destinations.
A-Basin’s story began as a shoestring postwar ski project. Through changing ownership, new lifts and terrain expansions, the mountain developed a reputation for serious skiing without losing its informal character. The Pallavicini lift arrived in 1978, and later expansions added Montezuma Bowl, The Beavers and The Steep Gullies.
A-Basin was also an early Colorado home for snowboarding. In recent decades the ski area expanded beyond winter with hiking, mountain biking, disc golf and a high-alpine via ferrata. Alterra Mountain Company purchased Arapahoe Basin in 2024.
Dramatic above-treeline terrain is one of the mountain’s signature sights and a defining part of its expert reputation.
The legendary Pali terrain and lift represent the steep, technical skiing that generations of A-Basin regulars love.
Front-row base-area parking spaces are famous for tailgating, grilling and a social scene unlike a conventional ski lodge.
High elevation and snowmaking help A-Basin pursue one of Colorado’s longest ski seasons, with memorable spring skiing.
Warm-weather offerings include hiking, biking, disc golf and a high-alpine via ferrata.
A-Basin has built its identity around passionate skiers and riders, community traditions and a relaxed, no-frills mountain spirit.
