I don`t post here but I have a ?
Off I-40 between Knoxville and Nashville is a place called Falls Creek Falls, it's a camp resor****er falls. My family has been there several times, I although haven't. So I don't know about the swimming part. But you might want to check internet on this camp ground. From everything they tell me, it's fantastic, and a great place for a reunion, especially for travelers. Kathy
fall creek falls is very nice, cabins on the lake as well, I believe there is also a campground picnic area somewhere near chattannooga or was when we lived there many years ago. It has a very strange name and as I recall was more of an amusement park, depending on where you want to go , heading to pidgeon forge in Gatlinburg is great as you can visit Dollywood amusement park. Tennessee has a great many parks spread throughout it other than fall creek falls depending where in the state you want to vacation.
