Sitting at 11,640 feet, Dercum Mountain greets guests as they enter the resort from the River Run or Mountain House base areas. Its trails offer skiers and riders long groomed beginner runs, including Schoolmarm, the resort's Family Ski Trail, as well as a variety of wide, rolling intermediate runs great for cruising. Dercum Mountain is also home to Keystone’s award-winning A51 terrain park, featuring a 60-acre collection of progressive terrain park features including boxes, rails and jumps.

Rising to 11,660 feet, North Peak sits directly behind Dercum Mountain and offers a variety of intermediate and advanced terrain, including long bump runs. It is home to Labonte's Smokehouse BBQ as well as The Outpost, where hungry skiers and snowboarders can grab a bite for lunch at the Timber Ridge food court or return later that evening for a gondola-accessed dinner at the Alpenglow Stube or Der Fondue Chessel.


The Outback, Keystone’s furthest and tallest peak at 11,980 feet, is an oasis for skiers and riders looking to enjoy powder turns and tree skiing. Take a short hike off the top of the Outback Express Lift for access to North and South Bowls where skiers and riders will often find wide-open turns and powder stashes.

In addition to Keystone’s three main peaks, Independence, Bergman, Erickson, North and South bowls offer skiers and riders incredible hike-to terrain and access to secret stashes, tree runs and powder laps across more than 1,000 acres. Terrain in North and South Bowl is easily accessible via a short hike off the top of the Outback Express Lift. Don't feel like hiking? A $20 shuttle ride on The North Peak snowcat (pick up at the Outpost building on North Peak) provides easy and convenient access to terrain in Erickson and Bergman bowls, which provide easy access back to lift-serviced terrain, or to Independence Bowl, which requires a hike out..
