The north side of the Santa Clara River Preserve features a trail system under development. It’s brand new, and changing quickly. The highlight is a trail that runs the length of the preserve from east to west, called (I believe) the Anasazi. It flirts with the cliff edge as you look for Native American rock carvings, then turns into singletrack for a mile of very fun semi-technical riding. This central trail connects to other trail options. So your ride can be a quick hit-the-highlights (from one end to the other and back is 6.6 miles), or you can easily run up 12 to 18 miles exploring the side trails.
Anasazi Trailhead: Drive all the way through Santa Clara and continue on 191 past Ivins. Just after a gentle descent, watch for the Anasazi Trailhead sign. Turn left into the dirt road where the stone thingy is holding an iron gate. Drive 0.4 miles and turn into the parking area surrounded by a wooden fence.
