“A super-steep spur off the westernmost section of Wilson River Wagon Road Trail.”
— Brock Warner
The name and topography suggest this is a horse trail, but the maps and signage indicate bikes are allowed on it. This super short trail is extremely steep and probably won't get ridden much by mountain bikers, although it does seem to see a lot of attention from other trail users. Expect to push your bike up and grip the brakes down.
