I honestly dont remember how to get there from the crab orchard exit. It was pretty darn close to the highway I went with some guys from TNVJC.org and they knew the area quite well. This trail system is part of a state park. It is free to ride on. I think it starts at moderate though, its a little different from windrock. I really enjoyed it there. Go with someone who as been there before, the trails are not marked very well at all.
