Okay, I personally would not suggest camping in Central, Eastern, or Coastal Carolina During July or August unless you are really used to the humidity... We hiked the very brief trails they have. Very flat, but if you manage to jump the fence (as we did) and make it to the water the sight is beautiful at the end of the day. This was the official end-of-summer trip.
