Barrel Trail at Green Valley
Named for the many huge barrel cacti along the trail, the Barrel Trail lies on the slope of a cuesta just southwest of St.George. There are multiple riding options, including longer loops with significant climbing, and quick excursions. The southern end, in fact, might seem confusing if you don't have a solid travel plan. The Barrel Trail accesses some extreme-tech stunts as an option for very skilled bikers. The ride starts at 2600 feet elevation, rising to 3300 (more, if you climb to the awesome viewpoint overlooking Stucki Springs). Total climbing will be about 1100 feet. Length of the figure-8 ride described below is 5 miles.

Getting there Green Valley Trailhead: Take the Bluff Street I-15 exit in St. George and turn west. Immediately turn south (left) at the first light. Go over the hill and at the T intersection at the bottom of the hill turn right. Head northwest about two miles on Dixie Drive. Turn left at Canyon View Road, heading uphill toward the Green Valley Spa. (If you reach a "Green Valley Market" with gas pumps, you just passed it. Turn around and backtrack to the second road on your right.) Drive past the spa onto dirt at the end of the road.  Turn right at the top of the mesa, then immediately left to drive down into the deep valley. Park in the open area in the valley bottom (N37 05.542 W113 37.967) and pick your route west uphill. (Note: the staging area is private property with a plan for development into homes. This area may change, making these directions invalid.)
Bearclaw Trailhead: Follow the directions above. But as you drop into the valley, aim for the big gravel road heading straight up the cuesta (just to the right of the sandstone canyon). When you reach the gate, turn R into the parking area (N37 05.340 W113 38.457). Start your ride by continuing up the doubletrack.
