Keystone Gulch is a 18.1 mile lightly trafficked loop trail located near Dillon, Colorado. The trail is rated as difficult and primarily used for hiking, mountain biking, and snowshoeing.
rating this trail as easy borders on criminal. long steep climb. steep pitches over roots and loose rocks. numerous unmarked intersections. steep tight switchbacks. not 5 stars either since half the ride is on roads.
Mostly dirt road so an easy hike and went off on a hiking path. Lovely hike.
Beautiful hike from parking area. Can go as long as short as you want. Waterfalls very short distance from parking.
Great groomed road for snowshoeing, gradual uphill the first 2 miles so it was a good workout! Woodsy hike on the other side of the river so a great place all around!
