One-way mileage through the canyon from the upper trail head to the lower trail head is 1.5 miles. Those wishing to do a loop can return along the road for a total of 2.5 miles round trip.
The upper trail head (unmarked) is along Road 400 (Cottonwood), 3.7 miles south of the turn-off to Grosvenor Arch. As you near the trail head, the road enters the narrower confines of Cottonwood Canyon. The trailhead is located at the bottom of a steep grade in a small valley of dramatic red and white rocky outcrops. There is a small pullout on the east (left) side of the road. Immediately across the road you will see a network of footpaths leading into the narrows. The lower trail head (unmarked) is 1.0 miles south of the upper trail head along Road 400 (Cottonwood). Parking for this trail head is on the west (right) side of the road, just before Cottonwood Creek emerges from the narrows and begins to run alongside the road. A register box is located approximately 50 yards west of the parking area.
