I recently did the 4-C trail at Davy Crockett National Forest. The night before I did the hike, I stayed here. There is no cost to stay the night or to park for day use here. It's very peaceful on this side and serves as the north entrance to the 4-C trail. There was on other camper there and they were no bother. I am not 100% on it, but it looked like there's only really two defined area for camping, but it doesn't seem like all that many people go there so you should be able to find a spot. There is a glorified porta potty and no water source, so be prepared for that, but it is primitive after all so you can't be mad about that. Definitely a good choice of place to stay if you on doing the 4-C, especially in a single day, so you can get started early.
