This is a great little ride, easily accessible from town. Follow the trail downhill from the parking lot. It will curve toward town then back to the North. At the sign for the Beck Hill Trail (goes into the state park--off limits to bikes), go left (West). After you go through a sandy wash, get ready for the short but sharp climb to the base of the Turtle Wall. The Turtle Wall serves up fun, slightly technical slickrock. Ride along the Turtle Wall to the overlook, then head south, now on the Paradise Rim trail. The trail will make a sharp left and provide some sustaines technical descent that will make you appreciate your suspension. As you continue East, look for singletrack opportunites to the left (North). If you go down, to the right, you'll end up in town and have to climb the pavement back to the parking lot. If you keep curving left, you'll rejoin the Turtle Wall and get to ride the fun part again on the way back.
From St George, head north on Bluff Street. After the intersection with Snow Canyon Parkway/Red Canyon Parkway, turn into the first parking area on the left.
