Try this link for a Bradford Ridge trail map. As Wizard says, it about 2.5 (or so) miles one way. The last 1/4 mile or so is very steep.

Note that the Deep Creek Volunteers Website provides directions to the Bradford Ridge Trail head from Highway 138 and I-15. This route is no longer available as the portion of Highway 173 between Mojave Dam and the trail head is now closed. You can access the trail through the community of Twin Peaks via Waterman Avenue (Highway 18 at the 210 Freeway), Highway 189, Grass Valley Road and Highway 173, north to the trail. I love this hike and do it regularly.
