The drive up the mountain was so spooky we turned around
I was a camp host for a few years back around 2005- 2009. I believe this place is a great primitive camp ground. Coming from Gilmer Co. You might need a 4x4, I've heard coming from Chatsworth is a little shorter but has some very tight curves. There are or were length limits for campers because of this. I think that tent camping is the best way to enjoy this place. Just call the closest Ranger Station to check the road conditions if there's been heavy rainfall. And as always leave your site cleaner than you found it.
Really nice primitive campground. Flush toilets but no electric or other "amenities", also no dump station or official water fill. There were several trailers in the campground when we stayed there, they were local and knew and understood the challenges of the road in, we made it in with our Prius. Most campers had tents and the tent pads are spacious and level. Lake Conasauga is beautiful; no cell service, no light pollution, no traffic noise, no wi-fi. It's busy on the weekends but worth it.
