This long 11.5km trail provides a challenge for even the most advanced riders. Dropping steeply into the valley along an old 4WD track the trail then levels out along the scenic Collie River before climb back up the Mill Brook drainage. A good level of fitness and lots of water is advised for this awesome ride.
It is possible to ride the trail in either direction. However I would recommend riding it anti-clockwise; descending the steepr Millbrook Gulley and climbing the more gentle Sailors Gulley
