There is a large map board just behind the car park at the bottom of the trails and there are others at various places. The map is indicative rather than precise but don't let that throw you. There is a forestry road that goes up to the top of the hill. The singletrack trails hang off it. Hence it's not difficult to find your way around. Overall, the area is reasonably visitor friendly.
There is a short easy trail for beginners called Hawk Eye that starts near the car park. Most of the trails are intermediate or advanced and they can be treacherous in places after rain.
The trails are generally old-school with not a lot of good fun stuff on them but there are couple of worthwhile jump zones. The newest trail called "Black Track" is the best. It's machine made with lots of fun stuff including some nice table tops. It runs down beside the forestry road.
