This is a short 2.5 mile loop that's about 1/3 doubletrack trail along Stanley Creek. As of the time of this writing (3/1/13) the trail section is in bad condition. There are downed trees across it at many intervals. I had to do significant pushing to get past all of the trees, but I did manage to do some riding. Also, be aware that there are a couple of very deep creek crossings. The gravel road section, on the other hand, is in great shape.
Upper Stanley Gap parking lot. (See GPS coordinates)
