Established in 1970 Keystone is the largest of the county's resorts. Keystone became home to Summit County's first gondola in 1984 and added a second in 1990. The resort is also Colorado's largest night ski destination. Keystone Resort comprises three incredible and unique mountains - Dercum Mountain, North Peak and The Outback. The mountains of Keystone offer some of the best terrain Colorado has to offer: steeps, bowls, bumps, glades, rails, hits, lights - you name it, Keystone has it. Copper Mountain entered the field as Summit County's youngest resort in 1972. Copper was designed with pure alpine sport in mind and is still known as a true skier's mountain. World-class special events and unique daily programming energize the Village in both the winter and summer. From fine dining to mountain biking, incredible concerts to mini golf - the Village's mission is to attract and entertain in the spectacular setting that is Copper. In 1961 the ski hill opened with the humble title: Peak 8 Ski Area. Little did the town realize that merely twenty years later Breckenridge Ski Resort would become an international powerhouse of skiing. Breckenridge's layout now features terrain on four mountains - Peaks 7, 8, 9 and 10. Each peak reveals its own character ranging from the family cruisers of Peak 9, to the bowls on 7, to the glades of 10, to the extreme altitudes and steeps of Peak 8 served by the highest lift in North America. "The Legend", what more can one say? In December 1946 Arapahoe Basin opened for its inaugural season with a single rope tow and a $1.25 daily lift ticket. While A-Basin has always been known for its legendary abovetimberline extremes, recent years have seen the maturation of its gentler terrain. Despite recent improvements to lifts and base area additions, Arapahoe Basin maintains it raw character as the pioneer of Summit County ski areas. At a spirited sixty years young, A-Basin never grows old.
