From Datil, NM, drive NM Highway 12 southwest for about 25.5 miles. Past mile marker 49, turn north onto Horse Springs Road (unmarked gravel), just before a ranch house. Drive 4.2 miles, and turn on a dirt road to the right. Pass through the gate, and drive 0.8 miles to a parking area (this road requires high clearance). From the parking area, a trail can be hiked or ridden on horseback to Nance Canyon.
