A great intermediate loop with some technical sections, root/stump jumps, and tight twists and turns to keep things fun. Mostly dense tree cover. Best ridden in the counter-clockwise direction.

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, except for the southeast aspect from Ladyslipper to Hillbender. The rest of the but can be snowpacked in with enough snowshoe and fat bike traffic.

Access Info

Access from the junction of Nemo and Powerline road
