Guinn Mountain Spur is a short, dead-end spur road off Jenny Creek that ends along the Guinn Mountain hiking trail. It is a tight, technical, and rocky trail with tightly encroaching pine trees that limit the width of vehicles willing to travel it. It is best suited for narrow vehicles such as UTVs, ATVs, and older jeeps. Users will be required to traverse watermelon and beachball-size rocks that can easily snag differentials and low-hanging undercarriage parts. The trail passes a few dilapidated cabin structures, crosses a creek, and has two sub-par campsites along the drive. Be careful at the end of this trail as the closure gate has been cut down, and it is easy to end up on the non-motorized hiking trail.
The primary purpose of this trail is likely an access trail for firefighting, EMS, and SAR operations.
