The Black Canyon Trail is a redesign of a very old OHV "trail"/route that runs from Lake Pleasant Road north to...well, wherever they decide to end it. The old route ran up to Mayer, basically, running along the eastern face of the Bradshaws.Dodi said:
I've ridden it several times from the "new" trailhead off New River Road up the "new" singletrack to its terminus at around the Agua Fria River. It is well constructed and not super-challenging but you get some great views and you get to ride in the high desert, which is a nice change for the low desert city folk. There are a couple gut-busting climbs, particularly on the out-and-back portion out to the river. There is at least one moderately dangerous descent, dangerous primarily because of the looseness.
Groovy ride, highly recommended if you live in that part of town and/or want to ride something less difficult than Go John @ Cave Creek Rec Area.
Trailhead is up a series of dirt roads that starts at 47th Ave & New River Road. Head west. Beyond that it's hard to explain. They're working on new signage.
