Description

From the Gregory Canyon Trailhead, head towards Baseline Road. The trail starts just northwest of this intersection.

From that intersection, the trail climbs steeply with switchbacks crossing the road many times along the way. There is one more steep push towards the end of the run. After this, the trail crosses the road once more before coming to a four-way intersection with the Range View and Ute Trail.
