This narrow 4WD road cuts through a deep and beautiful canyon. You can climb it to get to make a loop with Poleta Canyon or descend it with a shuttle.
From the end of Warm Springs Road, Black Canyon Road heads up to the southeast to get into Black Canyon. The road narrows along with the canyon as it heads up. The steepest, rockiest section is found just below a rock slide. Further in, it enters black rock, with willows and cottonwoods along a creek.
The middle section above here has been covered in sticks and debris to keep motorcycles out. It's legal for bikes, but not fun. The alternative route (Black Canyon to Poleta Climb (lower)) will prove a better option.
