Carter Caves State Resort Park Campground Dump Station

The road coming in is narrow with dropoffs, curvy, and quite a nail biter with a big rig. The water and electric hookups are shared between sites so may be quite a distance from your rig (bring extensions!). Sites are somewhat sloping, so again be prepared with risers. Try to be on the outside, since some sites in the middle are fairly close together.
All that being said, the park is clean (no info on shower or facilities since we are self contained), nice staff, absolutely beautiful, and a short distance to the fascinating cave tours.
