O'Fallon Park Loop

O'Fallon Park Loop Professional Review and Guide

"This popular gem in the Denver Mountain Parks system offers hikers-only trails close to Denver. About a fourth of the main loop is multiuse trail, shared by hikers, mountain bikers, and equestrians. Hike through a ponderosa pine, Douglas fir, and Rocky Mountain juniper forest, then across flower-filled meadows.

The trail drops into a peaceful and lush section along a little stream that runs through a Colorado blue spruce forest. A stand of aspens shimmers beautiful gold colors in autumn. With fishing in Bear Creek, picnic grounds, trails for those who love to hike, and grassy areas for games, bring the whole family for an outing that all will enjoy."

"While there are many square miles of Denver Mountain Parks along the Front Range, few are large enough to support a good mountain biking experience. O'Fallon is the exception. While not terribly long, it is a stout climb with a nice quick return on a variety of single-track trail surface and trail widths. Really consider the trail option to make for a longer, more fun ride.

Cross the bridge over Bear Creek and climb on wide trail. An obvious narrow single-track trail takes off from the wide trail on your right (0.4). Take this narrow trail and continue climbing on generally smooth and sometimes sandy trail passing a trail split on your left (the ride option). Keep going straight and continue to climb. Near mile 1.1 the single track joins a dirt road. Turn right and continue to climb on the road, quickly passing a two-track trail on your right. TERRAIN: Hardpack; some ruts and sand."
