Millbrook Trail is a 6.9 mile loop trail. The trail is rated as difficult and primarily used for mountain biking.
An epic loop that descends all the way from the Pile Rd trails to the Collie River - and then climbs back up again This long 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.
