Rusty Nail is a difficult rock crawling 4x4 trail that is a "shortcut" to the most popular and most difficult obstacles on the Golden Spike & Gold Bar Rim trails. This trail challenges the most seasoned veteran wheeler, both physically and mentally. Large, off-camber, undercut ledges, true to the Moab testament, make up the majority of the obstacles on Rusty Nail. Although there are only four named obstacles, the trail is riddled with numerous challenges and no bypasses. There are alternate routes on a couple of obstacles, but those routes are just as difficult, if not more difficult, than the main route.
