Little Oak Campground (update)
I talked with a friend this morning who camps at Little Oak nearly every year. He said that he was not aware of any contact #'s. He had gotten in touch with the host one time before, but that was no easy task. He believes that they shut down most of the campground the middle of October, but they do leave one loop (I believe there are 4 loops) open later into the year. The campground is nice and borders South Holston Lake. He said it was about 7-8 miles of gravel coming in from either direction, HWY 421 or Hickory Tree. They do not take reservations, so all you can do is show up and see if they have a spot.
