A great place to practice some basic, all the way to advanced MTB skills, before races, or just to stay in shape. It is rough, and expect to find some technical terrain

    The fire road is really overgrown. Lots of spiky plants and burrs to whip your shins the entire way down and stick to your socks and shoes.
