A great intermediate loop with some technical sections, root/stump jumps and tight twists and turns to kep things fun. Mostly dense tree cover.

This trail is becoming increasingly popular due to the Southern Valley Trails Project and is now a sanctioned trail by the Forest Service.

Winter access can be spotty and is not groomed, but can be snowpacked in with enough snowshoe and fat bike traffic.

Access Info

Access from the junction of Nemo and Powerline road
