Driving from Hatch, Utah take US 89N to State Hwy 12 and go east about 5 miles. Turn left at the entrance sign and drive about 1 mile down the dirt and gravel road to the parking lot on your right.
I recommend bracketing exposures about 1/3 stop and using a polarizer or graduated ND filter.
This .7 mile moderate trail is named for the fifteen arches in the area. The shot was taken about 500 feet from the top of the trail.
