Gray Rock is a private park that is only open to wheeling for certain events. There is a fee for entry, wheeling, and camping. There are lots of trails that vary from mild to wild, as did the Jeeps we saw at the annual Spring Fling. We only saw part of the park because of large-scale strip mining had cut off access to some trails. It’s too bad, but coal is important to the local economy, and the trails are still amazing for the relatively small area.
