Start out on a wide trail flanked by trees. On weekends it is crowded with hikers. If you go off on Wild Horse Trail, it is less crowded and there is some nice singletrack that goes by a pond. Then it becomes increasingly difficult to ride unless you are an expert. Washed out erosion with big stair-step timbers become the norm.
There are nice views as you hike your bike up the trail. There is some brief singletrack in other areas but even the combination of these would not make this close to being fun for MTBs.
