This has become a pretty well known MTB spot. It is mainly singletrack with not too much technical riding. Some of it is technical and you should be prepared for that. Hills can be pretty long but it won't get real hot so there's no problem there.
How to get there:
From Charlotte: Take Rt 77 north to Rt 40. Go west on Rt 40 past Asheville. Continue on Rt 40 until you see signs and exits for the park. Follow the signs to parking.
