This 4.0-mi (both ways) canyon route is popular with local trail runners. Vacationers like us found it perfect for a quick afternoon fix, amenable to both the youngest member of the family and the pooch. Several stream crossings mean you may find sandals preferable to other footwear. TO TRAILHEAD: From US-191 turn R onto Hwy 128 @ Colorado River, N of Moab. After 3.1-mi park on R side at Negro Bill Canyon trailhead.
