Location
The McConkie Ranch trailhead parking is ten miles from Vernal city center, driving west along Hwy 121, north on 3500 W, northeast on Dry Fork Settlement Road and finally north on the (still paved) McConkie Road, which crosses Dry Fork Creek, and also leads to the ranch, in which there is a small museum containing artefacts found in the vicinity.

Trails
Most of the petroglyphs are northwest of the parking lot, along a path signed 'Main Trail'. The first panels, a lot of which are somewhat faded, include animals, abstract shapes and simple figures; mainly petroglyphs also a few pictographs, and likely spanning a wide age range. A little further, beyond a short box canyon, are the larger and more dramatic figures, including the headhunter panel and several similar groups of intimidating-looking figures, plus a depiction of a sad face next to a pair of detached feet but no body, perhaps referencing cannibalistic practices. The trail ends after a third of a mile near a large pair of figures known as the twins panel. Back at the parking lot, another path heads southeast for 0.6 miles passing more designs, including perhaps the best of all, the three kings panel, just beyond a side canyon. This actually contains at least seven anthromorphs, and various other designs including spirals, some of which underlie the larger figures so are clearly older.
