Santa Clara Stucki Springs Road to Stucki Springs Loop
This is an intermediate-technical 13-mile loop ride. It's a way of riding the Stucki Springs Loop from the preserve parking lot at the Barrel Roll trailhead. Navigation can be a little tricky on the cutoff trail. If you don't have GPS, just hold to the general direction and pay attention to the miles. You should arrive without too much "exploring."

Santa Clara trailhead:  In St. George, head north on Bluff Street and turn left on Sunset Blvd. Drive 3 miles west on Sunset through Santa Clara. As you're reaching the end of Santa Clara, look for a road crossing the river on your left. It's about 200 feet before the Jacob Hamblin Home (which will be on your right if you pass the turn). Turn and cross the river and follow the road as it turns right. About 0.4 miles from Hwy 191, turn left onto the dirt Stucki Springs road as it climbs steeply south. At mile 0.7, turn right at the sign "Santa Clara Preserve" or "Cove Wash Trailhead." Pass the water tank, and at mile 1.3, turn right again through the fence. This road will veer left to a log-fence parking area at mile 1.5, N37 07.253 W113 40.508.
