I went camping here this past weekend. It was an extremely pleasant experience. My wife and I camped in a tent in the Primitive section, with nary but a fire to keep us warm during the cold evenings. During the day we hiked the assorted trails and visited the Nature Center. We were lucky enough to visit while they were feeding some turtles and snakes, so that was fun to see.
It got really cold on Saturday night, so we got some extra firewood and the guy at the office was very nice, helpful, and chatty.
The only downside to this place is that it's very close to both South Tryon and the airport, so traffic noise and airplanes were constant. I can't hold it against the place though, and if I wanted solitude I could camp literally anywhere else. For anyone seeking a not-too-far-away-from-civilization outdoor experience, this is your place.
