Poison Spider Mesa Trail climbs switchbacks up and across Poison Spider mesa providing very attractive views over the Colorado River of the Behind the Rocks area and Moab Valley. The route across the mesa involves sections of open slickrock requiring some trail finding skills. A few short spurs to the right give the best views. The small loop that begins at mile 5.6 should be driven counterclockwise to avoid having to ascend a sandy hill. At mile 6 is the accurately named Little Arch.
