This trail is found on the left as you head uphill from the intersection of Cable Line and Porter Roads.
This is a loop that can be ridden in either direction, but is described in the clockwise direction here. At the split stay to the right. Shortly on the right there will be an old quarry. The trail then turns uphill and continues for a while along a ridge. The last mile is frequently very rocky. Exit at the intersection to head back to Porter Rd.
