Mountain, Keystone Colorado

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 $10 (cash only) shuttle ride on The Outback's snowcat provides easy and convenient access to terrain in North and South Bowl. Want more?

Uphill Access Guidelines

Non-paid/Uphill users of Keystone Ski Resort assume all risks associated with access. The ski area is not maintained for uphill access and trails are not patrolled outside normal ski area operating hours, therefore emergency services may not be available. Ski area operations are 24 hours and users may encounter vehicles, slope and trail maintenance activities, snowmaking, and other hazards not typically present during operating hours. Users are subject to the Colorado Ski Safety Act. Users must abide by the following rules:

  1. 1. Uphill access is only permitted outside of public operating hours. All uphill users must be clear of the mountain by 8:30 a.m.
  2. Abide by all posted signs, including all closed signs. Stay off all posted CLOSED trails and areas. Stay off Black Diamond terrain. Stay off all Terrain Park features and jumps
  3. Avoid all areas where machinery is operating. Snow Cat winching operations may be in progress. Strobe lights mean stay clear and avoid the area altogether.
  4. Call the trails/winch cat hotline at 970-496-4033 before accessing the mountain. This number provides important information about seasonal restrictions and ski area operations that may impact access.
  5. Stay towards the center of the trail.
  6. It is your responsibility to make yourself visible to approaching snowmobiles or snow cats (Especially when it is dark or twilight). Wear reflective clothing; it helps make you more visible.
  7. Once up the hill, no one may ride a lift without a valid ticket or season pass.
  8. Dogs, other than Service Dogs, are not allowed.
  9. Please be advised that fat tire biking and/or mountain biking is prohibited on the mountain during the winter season, both during daytime and nighttime operations.

Uphill Access – Mountain Winter and Summer Preparation

The ski area begins operations during the fall and the spring to prepare the slopes and trails for opening. The work taking place makes it unsafe for public and even impassable at times for skiers or hikers. Uphill access will not be allowed on trails during mountain winter or summer preparation. Keystone Ski resort will open trails when operations are compete, which could extend beyond the ski area opening or until the resort has adequate terrain to safely permit these activities. Areas in which preparation activities are taking place may be closed from the bottom of Keystone Ski Resort trails, in these cases, “CLOSED” signs will be placed at the bottom of the closed area to inform those travelling uphill of the closure. When such closures are in place, only authorized personnel are permitted in the area. When such closures are in place, you must select an appropriate alternate route.

Keystone Ski Patrol recommends that skiers and snowboarders call in advance to check on current conditions and safety precautions. At all times, Keystone Ski Patrol urges the public to adhere to all closure signage and instructions by Keystone Ski Patrol. Violations are enforced by Keystone Ski Patrol and Keystone Emergency Services.


Parking is allowed in the Montezuma lot in River Run or the Porcupine lot at the Mountain House base area.
