Singletrack with lots of tight turns, and some minor obstacles. This trail is generally ridden clockwise. If riding clockwise, the first half of this trail is slightly flowier, in less dense forest and in some clearings. After you pass the Grassy intersection, the trail becomes more technical and twisty, slightly overgrown in some areas, but never unhealthily overgrown. The first half, if going counterclockwise, is generally the easier half.
Access Info
Starts & Ends off of Brain Wave, also accessible in the middle from Grassy.
