Head south out of Cannonville toward Kodachrome basin on the Kodachrome Basin road for 2.7 miles to the Skutumpah Road.

The trailhead is right on the edge of Bull Valley Gorge, and gives impressive views of the canyon. From the car park, walk on the well-defined trail up the canyon on the north side. There is a trail register within 100M of the trailhead. Follow the trail for 10 or 15 minutes until the canyon becomes shallow and easy to descend to the bottom.

Head down the canyon. The best park of Bull Valley Gorge is right above and under the bridge. Before getting there, however, you will be faced with several downclimbing challenges. These likely change with every flood, but in 2007, all were fairly reasonable to downclimb and reverse. The most difficult, a 3 m ( 10 ft. ) chimney downclimb had a fixed rope when I visited. Be careful not to downclimb anything you cannot reverse unless you plan on taking the optional exit mentioned below.

Just after going under the bridge, the canyon begins to open. From here down, the canyon is a beautiful deep canyon, but you have passed the narrowest section. You can turn around here and reverse the canyon back to your car whenever you feel inclined.
