Owned by nearby Vail Resorts, Keystone is usually one of the first resorts in Colorado to open each autumn and one of the last to close. It is also home to North America's biggest ice skating rink (5 acres).

The three mountains at Keystone are stacked up one behind the other moving away from the base - an unusual and interesting layout. The terrain gets more challenging the further back you go. The first mountain, Keystone, is largely intermediate terrain. From the peak, the Outpost gondola goes to the middle mountain, North Peak. Outback Mountain, the farthest back of the three features three superb bowls with above tree line skiing.

The resort sprawls around the base of the ski area with slope side condos the best place to be for ski in/ski out access. There are over three dozen restaurants in the area and non-ski activities include ice skating and hockey on the mega rink, night skiing and snowboarding, snowmobiling, snowshoeing and indoor tennis.
