From Hwy 191 and Main Street, Vernal, head west to 500 West. Turn right and drive north on the Maeser Hwy to 3500 West. Turn right and drive about 10 miles the Red Cloud Loop Fork. Turn right, cross the bridge and continue on the paved road for another 2 miles into Dry Fork Canyon. Watch for the sign marking the ranch access road road. The parking lot for the petroglyphs is easy to find and is about 3/4 of mile off the main canyon road. The rock art is on private property and you may need to pay a fee to see it. It is worth the price.
