The north end of this trail is essentially a gravel access road, which progressively narrows as you approach the cedar bridge at the Ferlin's Folly intersection. Here the trail turns left and changes to singletrack, winding just downhill from Ferlin's Folly. Once it intersects the utility right-of-way, it crosses Colvin Run and ends at Apache.
