TN Cruise Lite - Tanks for the post. We live in Seymour and are always looking for something within a few hours and will have to check out Yarberry.
Concur about Roan Mountain State Park. We go up there twice a year, once in the Spring for the Rhododendron festival, and sometimes for the trick or treating in the park, all the locals come out for trick or treating in the campground and most of the camp sites are incredibly decorated, we gave out over 1,200 pieces of candy within the first 45 minutes. The kids loved it.
As for spaced out camping not exactly near Knoxville but Fall Creek Falls state park is a really nice place, and full hook ups available.
