This trail is typically ridden from west to east. Start at the trailhead for the Unbeatable boulder, in the southern part of the Box Canyon climbing area.
The trail starts out as rocky singletrack and eventually joins the Black Canyon Arroyo. Singletrack meanders across the arroyo and eventually disappears. Follow the arroyo to the east and look for an exit to a two-track on the north.
Note - this trail is rustic and the arroyo is unimproved. Expect slow, techy riding.
