Located in the National Forest; just be aware of hunting seasons.
From the Bishop Knob campground, go out past the entrance and turn left. Look for another left onto Coe Road (FSR #81). Follow 81 for 100 meters, then look to the left for the Cranberry Ridge Trail.
It's a fun, downhill, and moderate singletrack to near the Cranberry River. Expect nice sweeping turns in the forest, with a mix of double and singletrack feel before returning via nearby gravel roads. It crosses one gravel road—go straight ahead here. When it comes to the second gravel road, turn left on 7/6 and left again to head up the hill on Coe Road (FSR #81) to return to the campground.
The trail is used on the fun Cranberry Ridge Loop ride from Bishop Knob campground that is mostly downhill with some short climbs.
