The trailhead starts just off of highway 89A toward Lee's Ferry.

From Page, AZ:
Go south on highway 89 to Bitter Springs in about 25 miles. Turn north here onto 89A, and follow it 14.3 miles to just after crossing Marble Canyon and the Colorado River. Turn right on the signed Glen Canyon Recreation Area / Lee's Ferry road. Follow it 1.3 miles to the signed Cathedral Wash pullout on the left side of the road. This is the trailhead.

From the parking area, go down Cathedral Wash, entering Grand Canyon National Park within just a few minutes.

The first section is pretty, but not particularly impressive. Ledge walking on the right can avoid a possible pool or two in this section.

When you reach a dryfall, you are about to end the best section of the canyon. The first dryfall can be bypassed by hiking on the right a minute, then downclimbing a corner to a ledge above the canyon floor. Follow the ledge a minute or two down canyon until you can get back to the canyon floor.

Continuing down canyon, the next dryfall can also be most easily passed on the right, while the one after can be passed on the left. Pools in this section can all be bypassed on ledges on either side of the canyon, just look around for the easiest route.

Unfortunately, the narrows end all too quickly at the Colorado River. Return the way you came.
