      More fun ridden clockwise (as seen from above) for an average rider.

      CCW!? Only if you're an XC beast or have trials skills. If you're an avarage rider and favor riding over walking, do this clockwise!

      Good loop, and accurately described. Intermediates should not skip this loop. It has good flow, CCW is best, and the rock gardens add interest and challenges. Most can be cleaned, in sessions if not initially, or easily hiked by intermediate riders. This is fun and challenginf single track to complement the other, wider trails in the CMSP network, which has excellent wayfinding and interpretive signs throughout.

      We hope you've been enjoying Trailforks!
