Lake Cumberland State Resort Park is right outside Jamestown, Ky. Easily accessible and on the way to or from Daniel Boone National Forest.
First there are plenty of things to do. A large Marina on the lake gives you options on your mode of travel to get to the park. The Lodge offers some sweet views of the lake from the rooms and overlook. There are tennis courts, disc golf, miniature golf and a horse stable.
The campground is midsize. But be aware that if you have a larger rig you aren't getting in any of the "branches" of the campground. That being said there are plenty of tent sites.
Two drawbacks for me, there is only one trail an approximately 4 mile loop with some okay overlooks and semi strenuous terrain. And two the campground is loud. The noise from the marina carries and the other campers while I was there were very noisy late into the night.
