Zen Trail
This trail is probably the most technical ride in the St. George area. It has quite a few little rock tricks that challenge the rider. I recommend it for advanced riders, or for intermediates with a good attitude and a sense of adventure. It doesn't take that long to walk your bike through a spot that spooks you. The ride has much to offer. It's much like Gooseberry Mesa, if Gooseberry were tilted onto a slope. The trail starts at 2700 feet, just off the road to the northern Bearclaw Poppy trailhead. You can take either of the first two doubletracks to climb -- I strongly recommend the first DT, because it's much more fun, and offers some tech riding before the two routes join. Top altitude is 3450. There will be about 1100 feet of climbing during a loop ride that returns by the lower singletrack. The loop is 6 miles.

Getting there:  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. Head for the big road that goes up the bluff, on the right side of The Gap -- the sandstone canyon. But just before that road starts to climb, mosey to the left and park where you can start riding up the doubletrack on the LEFT (south) side of the sandstone canyon.
