Keystone Bike Park – Lift-Served Downhill in Summit County, Colorado

Keystone Bike Park is on Dercum Mountain at Keystone Resort in Summit County, Colorado. Keystone Bike Park has more than 30 miles of lift-served singletrack, so it is one of the bigger gravity parks in the state.

Trails and terrain

The trails range from beginner flow trails to blue jump lines and expert technical descents. Riders who are new to downhill riding should start on the green trails and work up from there.

Events and riding days

In 2025 the resort listed the bike park as open Thursday to Monday, 10am to 5pm, through Labor Day, with fall bonus weekends after that. The park also hosts races. The resort’s summer news listed the Revolution Enduro and a Downhill Rockies race in August.

Passes

Keystone is part of Vail Resorts, and Epic Pass holders get some summer benefits. Bike park tickets and passes are sold through the resort website. Check the site for current prices, rentals and lesson options.

Good to know

The 2026 opening day was reported as late June, and the season usually runs into September. The park sits at high altitude, so drink plenty of water and take it easy on your first day. A full-face helmet and pads are a good idea on most trails. Book tickets online at keystoneresort.com before you go.
