Trail Overview
The trail starts immediately after the Sand Hollow Wash Bridge off Highway 91. A sharp right after the bridge will bring you down into the wash. The highlight of this trail are the two approximately 20-foot tunnels under the Interstate 15 freeway. The tunnels are wide enough for full-size vehicles. The trail is relatively easy with a few one-foot waterfalls, but the higher rating comes from the one four-foot ledge. Rocks appeared to have been stacked at some point by the previous trail riders. Stacking rocks and depending on the line could bring this down to a two or three-foot ledge. The time for this trail is approximately one hour due to the main obstacle and how much time is spent there, and how many vehicles are in your group. You could bypass this obstacle if you ran the trail from North to South, to just go through the tunnels.

Difficulty
This rating is based on the approximately three-foot obstacle/ledge. It's not quite a seven because that requires obstacles and ledges up to five feet.
