Arapahoe Basin Ski Area, commonly called A-Basin, is a high-alpine ski and snowboard destination located on U.S. Highway 6 near the summit of Loveland Pass in Summit County, Colorado, approximately 68 miles west of Denver. Operating since 1946, it is one of the oldest ski areas in Colorado and sits almost entirely above treeline, giving it a distinctly rugged, above-timberline character. Its extreme elevation—base area at roughly 10,780 feet and summit at 13,050 feet—fuels a season that regularly extends into June and occasionally early July.
What is Arapahoe Basin known for?
Arapahoe Basin is best known for its extreme elevation, reliably long ski season, and expert-level above-treeline terrain, including the famous Pallavicini Face and the East Wall, a zone of steep chutes and open bowls that draws advanced and expert skiers from across the country. The ski area covers approximately 1,428 acres of skiable terrain spread across six distinct zones: the Pallavicini area, the Main Mountain, the Beavers, Montezuma Bowl, the Steep Gullies, and the Pali area. It operates without a resort village, maintaining an unpretentious, mountain-focused atmosphere that regulars prize.
Best things to do at Arapahoe Basin
Beyond skiing and snowboarding on over 100 named trails, visitors can access the Lenawee Mountain summit ridge at 13,050 feet for panoramic views of the Continental Divide, ski the High Noon Express lift to reach the upper mountain bowls, and take a beginner lesson at the Molly Hogan surface lift area near the base. Snowshoeing and uphill skinning are permitted on designated routes during ski season. In summer, the mountain hosts hiking and the popular A-Basin Mountain Bike Park on lower slopes.
Where to eat at Arapahoe Basin
Arapahoe Basin’s most distinctive dining spot is the Black Mountain Lodge, a mid-mountain full-service restaurant accessible by ski or the Black Mountain Express lift, serving hot comfort food including soups, burgers, and Colorado craft beers with views of Montezuma Bowl. At the base, the Sixth Alley Bar and Café inside the day lodge provides casual counter-service dining with breakfast burritos, sandwiches, and hot drinks. The legendary Beach—a south-facing parking-lot tailgate zone—is a cultural institution where skiers grill, socialize, and extend après-ski well into the afternoon on sunny spring days.
How to get to Arapahoe Basin
Arapahoe Basin is reached via U.S. Highway 6 over Loveland Pass, located about 6 miles east of the Dillon/Silverthorne interchange on Interstate 70 (Exit 205) in Summit County. The drive from Denver takes roughly 75 to 90 minutes depending on traffic and road conditions. Summit Stage, the free public bus service for Summit County, runs routes connecting Dillon, Keystone, and other nearby towns, with a stop serving A-Basin; no on-site lodging exists at the ski area itself, making Dillon, Silverthorne, Keystone, or Breckenridge common base towns.
Best time to visit Arapahoe Basin
The optimal time to ski A-Basin is March through May, when the snowpack is deep, the days are long, and the above-treeline terrain in Montezuma Bowl and the East Wall is fully open—combined with the festive spring skiing culture at the Beach tailgate area. Opening day typically falls in late October or November, and closing day is frequently the latest of any Colorado ski area, often in June. Weekday visits are significantly less crowded than weekends, given A-Basin’s popularity with Front Range day-trippers.
Where to hike and explore near Arapahoe Basin
The Lenawee Trail begins near the A-Basin base area and climbs toward Lenawee Mountain along the Continental Divide, offering tundra hiking and views of Montezuma Valley below. Nearby Loveland Pass itself, just a few miles west on U.S. Highway 6, provides a trailhead for Continental Divide Trail access and sweeping 360-degree views at 11,990 feet. The town of Keystone, roughly 6 miles west via Highway 6 and then U.S. Highway 6 through the Snake River valley, offers additional restaurants, lodging, and the Snake River Saloon.
