Campgrounds in TN or KY

Anyone have any recommendations for kid/family friendly campgrounds in either Tennessee or Kentucky? Something preferably with a small lake and hiking trails and accessible via a 5th wheel camper.
Here are a few of our favorites.

- Red River Gorge/Natural Bridge State Park, Daniel Boone National Forest

- Cave Run Lake/Camp Zilpo, Daniel Boone National Forest

- Big Bone Lick State Park - very cool for the kids and adults, near Cincinnati and you could take in Kings Island as a diversion from camping for a day, many
awesome rides there.
