Tour Operator: Keystone Resort is comprised of three mountains, Dercum Mountain, North Peak and The Outback. Each mountain offers steeps, bowls, bumps, glades and rails. The Outback's tree-filled glades protect powder stashes for tree skiers, plus two immense bowls for those looking for an off-piste experience. Keystone is home to the largest single-mountain night skiing experience in North America. The entire mountain is open for evening skiing, offering fifteen other runs to ski and ride under the stars. Area 51 is Colorado's largest terrain night park and stays open during 8p.m. and 10p.m. on weekends. Fun off the mountain include tubing, cross country skiing, snowshoeing, or you can skate all day and all evening on the five-acre frozen surface that is Keystone Lake, the largest outdoor maintained ice rink in the country. Top it off with two distinct villages full of wonderful restaurants, a vibrant nightlife, unique shops and a wide variety of lodging options and you have a perfect ski holiday for the whole family.
