Several roads are available to mountain bikes in this area. All Forest Service roads outside of the High Uintas Wilderness boundary are open to mountain bikes. This trail was designed for ATVs and mountain bikes. Please yield the trail when required. Interpretative sights may still be under development along the way. One site is a picturesque view of an interesting geological feature called the Yellowstone Ledges from which Yellowstone Canyon derives its name. Another site is on Lake Fork Mountain and offers excellent views into the High Uintas Wilderness Area.

From Roosevelt, travel north along UT 87 to Mountain Home, then north to Yellowstone along FR 119. A parking lot and trailhead are located in the lower Hells Canyon area just past the Ashley National Forest boundary. The trail begins in the lower Hells Canyon area of Yellowstone Canyon, along FR 119. At its junction with FR 196, head west along a good dirt road. Continue along FR 196 as it climbs and winds its way towards Petty Mountain. Pedal across Flea Flat and through Bear Park. There is a spur there to Lake Fork Mountain. At Mill Park, the trail bends northeast and intersects FR 227 at Mill Spring. Take a right onto FR 227 and head southeast down through Hells Canyon back to the trailhead.
