Trails continue to grow around an increasingly popular destination in Colorado.

Frisco Peninsula Recreation Area makes up the forested, rolling landform bordering the Summit County town and Dillon Reservoir. Rangers know local regulars by name, “and have found this summer more users coming up from the Front Range,” said Erin Socks, general manager of Frisco Adventure Park.

“Many,” Socks added, “have indicated that the Peninsula is their favorite place to recreate in Colorado.”

The trail system has turned heads in recent years with additions called Aftermath and Sky Pilot. The downhill mountain bike-only trails swoop and soar for thrilling drops and jumps — on par with BMX-style features found at lift-served ski resorts, fans have praised.

Now comes a trail “that will be appropriate for intermediate riders,” said Mike Melkonian, Frisco’s Nordic and trail maintenance lead.

Enter the half-mile segment called Wildhack. Also for downhill bikers only, the newly opened ride includes a wooden feature that flies over Eureka Patch Trail.

Meanwhile, another one of Peninsula Recreation Area’s signature trails — one frequented by hikers and runners — is being extended.

Construction started in late July on a mile-long addition to the Perimeter Trail, which explores Dillon Reservoir’s shores. The extension will connect the recreation area trailhead to a crossing with the popular commuter path through the county known as the Recpath.

And so the vision for Peninsula Recreation Area continues to take shape, as outlined in a 2019 master plan that sought to establish year-round recreation beyond Frisco’s Nordic center and tubing hill. This was through an agreement with the peninsula-owning U.S. Forest Service, which sought fire mitigation in conjunction with trail development.

Leadership has said about 90% of the envisioned trail system has come to fruition.

“The Frisco Backyard plan would be the next big step in trail additions and connectivity for year-round multi use,” Socks said.

Similar to the Peninsula Recreation Area but on a much larger scale, the Forest Service has proposed a project treating fuels across 1,250 acres backdropping the town. The Backyard encompasses Rainbow Lake, Miners Creek, Mount Royal and Ophir Mountain — around where some trails would be closed, others would be built and others re-rerouted, according to an environmental analysis.

The Forest Service’s project webpage indicates work could start next summer.
