The trail head is 2.5 miles north of Utah Route 95 along a BLM gravel road. The road is a north turn just after passing through the engineered notch in the massive sandstone of Comb Ridge. The trail is mostly an ATV trail so the walking is fairly easy. This trail head is also the starting point for a hike to Hotel Rock. Look for the Walnut Knob petroglyph site in the trail head area also.
There are many creek crossings but in fall there is not much water to step through. The trail is sandy and meandering much of the way.
Within the first ten minutes of hiking there is the fairly large Arch Canyon Ruins site that has several wall sections still standing and many collapsed rubble pile structures, and several examples of petroglyphs on the sandstone canyon walls.
After that site, there are small and inconspicuous sites higher in the canyon walls. I saw four that I'm sure were sites. I saw other possible sites but they were so far up the canyon walls that it was difficult to tell even with binoculars. On this hike I was focused on reaching the two large arches and didn't stop at the ruins small sites. On a later hike to the Hotel Rock side canyon I looked at the ruins more closely.
