Trail Map:

Rider's Comments: Eight-mile loop. The first three miles are mainly flat double and single track. There's a short climb followed by a downhill and rolling hills. Half of the trail is a flat wide country road closed to auto traffic, the second half winds through forest and meadows and along ridges and many streams.
