From the car park head west down the slope to pick up a prominent cairned trail. The route you are to follow was constructed by the Bureau of Reclamation in the 1950’s to get horses and equipment down to the site of a proposed dam, which was to be located near Redwall Cavern.

The path leads down into the drainage of Shinumo Wash only to leave the wash on the left a short distance later to bypass a large pour-off. The route then zig-zags steeply down through the Kaibab and Coconino formations. Once through the Coconino, the path traverses the steep slope in a northerly direction before dropping steeply down a series of tight switchbacks to the top of the Supai at the bottom of the wash.

Turn left and rock hop down the wash. A short distance down canyon, look for a cairned path that begins on stream left. This good trail will allow you to bypass the majority of the rocky bed of the wash, saving time and effort. The trail crosses the wash several time as it descends the length of Shinumo. Look carefully for cairns on the opposite bank where it crosses.

Eventually the path crosses Shinumo Wash at the head of some Redwall Narrows. It then climbs up the other side and begins winding its way downriver on the top of the Redwall. After about 1.5 miles the trail branches above Fence Fault. Right will take you down to the small beach at the mouth of Fence Fault. If you continue straight the path continues to wind along the Redwall for another 3 miles or so with views to the west of South Canyon, Stantons Cave, and Vaseys Paradise and to the south of Redwall Cavern. When ready return the way you came.
