Summit County

Four World-Class Mountains Along a Twenty-Mile Stretch of Highway

Summit County is Colorado high-altitude ski capital. Within a twenty-minute radius along Interstate 70 and Highway 9, visitors have access to four major ski resorts: Breckenridge, Keystone, Copper Mountain, and Arapahoe Basin. The advantage is extraordinary variety: you can ski high-alpine bowls above 12,800 feet at Breckenridge one day, cruise manicured groomers and night ski at Keystone the next, tackle steep naturally divided terrain at Copper, and finish with legendary spring tailgating on The Beach at Arapahoe Basin. Base elevations sit between 9,100 and 10,780 feet, making acclimatization and hydration essential.

Snowpack & Climate Intelligence

Summit County enjoys high elevations and a cold continental climate that preserves snowfall. Average annual snowfall ranges between 300 and 360 inches. Because base elevations start above 9,000 feet, snow stays cold and light, particularly in the north-facing tree glades of Keystone and Copper. Arapahoe Basin East Wall and summit bowls sit above timberline at 13,050 feet, allowing the resort to remain open well into June.

Transit, Airports & Mountain Roads

Summit County is located 70 to 90 miles west of Denver via Interstate 70. Airport shuttle services like Epic Mountain Express and Peak 1 Express connect directly from Denver International Airport. Once in the county, the free Summit Stage bus system provides complimentary transit between Frisco, Breckenridge, Silverthorne, Dillon, and Keystone, allowing visitors to travel without a rental car.

Season Pass Coverage

Vail Resorts operates Breckenridge and Keystone on the Epic Pass. Copper Mountain and Arapahoe Basin participate in the Ikon Pass. This makes Summit County a versatile base where travelers holding either major megapass can ski multiple mountains during a single trip.
