Part of the Hermosa Creek Trail System.
Jones Creek / Pinkerton-Flagstaff / Dutch Creek Loop: To access Jones Creek / Pinkerton-Flagstaff / Dutch Creek Loop from the trailhead parking area near the bathroom, backtrack on Lower Hermosa Road. Jones Creek Trail starts several hundred yards up the road on your right.
Climb Jones Creek Trail for about 5 miles where it enters a grassy meadow in a stand of aspens. Turn left here onto Pinkerton-Flagstaff Trail and continue climbing along the ridge. You will encounter several hike-a-bike sections if you are mountain biking this loop. This section along the ridge is about 4-5 miles long and it will take you some time.
In a heavy aspen treed area the trail joins with Dutch Creek Trail. Turn left here and downhill. Dutch Creek Trail is a mostly downhill trail that runs along the creek and through lots of aspen groves and creek crossings.
The final 1/2 mile of Dutch Creek Trail includes a hefty climb before a fast descent and a connection with Hermosa Creek Trail. Turn left on Hermosa Creek Trail and ride 4 miles back to the trailhead and the start of your ride. Ride length is approximately 19 miles.
