Porcupine Rim Bike Trail

The Porcupine Rim Trail starts 7 miles from the Entrance Station at the east end of the recreation area. The first 11.2 miles of the trail are open to bikes and motorized vehicles. After this point the trail departs from the dirt road and becomes a single track suitable only for mountain biking and hiking. The trail is rated a 4 (difficult), on a scale of 1 to 4. It includes a 3-mile, 900-foot ascent from the trailhead to Porcupine Rim and then an 11-mile, 2,800-foot descent to the Colorado River. One of the great attractions of the trail is the stunning view it offers of Castle Valley from the top of the Rim.
