Keystone, Colorado is a resort community established in 1970. It is located at 9,320 feet in unincorporated Summit County with current population of 845.

While it was a largest resort in the county at the time of it's opening, it also became a home to the first gondola in Summit County in 1984 and second gondola was added in 1990.

Keystone's ski and ride terrain consists of three mountains - Dercum Mountain, North Peak and The Outback, and offers great variety of runs, terrain park  (A51) and the only night skiing in the county!

Over the years Keystone has evolved into a year-round mountain resort with newer River Run Village and well-established Lakeside, as well as state-of-the-art Conference Center.

Keystone offers some of the best dining in Summit County with high-ranked on and off-the-mountain restaurants - Alpenglow Stube, Fondue Chessel, The Ranch, Ski Tip Lodge, Summit Seafood Company and Big Horn Steakhouse to name a few.

Keystone Resort offers numerous activities any time of the year - from skiing, riding, ice skating, sledding, tubing in the winter, to mountain biking, paddle boating, hiking and golfing in the summer.
