When the snow melts, the same mountains that make Summit County a ski mecca turn into a summer riding paradise. You can session a lift-served downhill park, cruise a paved path along a reservoir with the kids, or grind out an alpine singletrack loop — often all in the same trip. Here’s how it breaks down.

Lift-served bike parks

Keystone Bike Park is the headliner — one of the largest downhill parks in Colorado, with a gondola and lifts serving flow trails and technical descents for every level. Nearby Trestle Bike Park at Winter Park is another world-class option, and other resorts (including Copper) run summer lift operations. Ride the lift up, session the trails down — rentals and lessons are available at the base.

The paved rec path

Summit County’s crown jewel for casual riders is its paved recreation path — 50+ car-free miles connecting Frisco, Dillon, Breckenridge, and Copper along Dillon Reservoir and the creeks. It’s flat-to-rolling, stroller- and kid-friendly, and genuinely scenic.

Singletrack & alpine trails

For dirt, the classic Peaks Trail links Breckenridge and Frisco through the forest, and sections of the Colorado Trail and Gore Range routes deliver big-mountain singletrack. These sit high and rugged — bring water, layers, and respect afternoon storms.

Book a guided trip

Guided rides, shuttle laps, lessons, and full-suspension rentals are widely available through local outfitters and the bike parks. Direct booking links for guided trips and rentals are coming as we finalize our activity partners.

Gear & what to know

A helmet is non-negotiable, and the high, dry air dehydrates you fast — carry more water than you think, plus sun protection from our altitude & sun kit. New to elevation? Read up on altitude sickness and take your first ride easy.
