Head north out of Vernal on US-191 N toward Steinaker Reservoir. Follow US-191 from downtown Vernal for about 7 miles to mile post 360.1 where a good dirt road leaves on the left (west) side of US-191.

Follow this dirt road, ignoring smaller side roads, for 1.1 miles to the hiker trailhead, which is a large parking area with a pit toilet. There is a gate at the end of the parking lot where the dirt road becomes rough and descends to a wash bottom.

OHV Route: Most will want to start hiking at the hiker trailhead. If continuing by vehicle, go through the gate and down across a deep wash. The road here has some deep gullies. Stay left/straight past 2 side roads on the right after crossing the wash until a third road on the right is marked with a Moonshine Arch sign. (0.25 miles from the gate) Take this right as it doubles back toward the way you came. Stay left at junctions. There is a small parking area just before the road begins to climb and get rougher. Follow it to its end and the arch.

Hikers: Go through the gate and follow the road. It crosses a deep wash, then the road splits. Go right at this junction, which is signed for hikers. In just a minute another junction is encountered, go left here.

Finally, just about a 1/4 of a mile from the trailhead is the final junction. Go right here, as the road begins climbing and getting rougher. Follow the road all the way to the arch.

Return the same way.
