I give 4 stars for the hiking trails and activities in the area and 3 stars for the campground itself. This is one of the most popular parks in GA. It is usually crowded and books quickly. Sites are VERY close together. No privacy at all. I had a walk in tent site. Seemed private on the creek, but the cars coming down the road shined their headlights in the tent. Also, from about 4am to 10pm you hear the constant traffic on the nearby highway. This highway is curvy and goes down the mountain, so when I say traffic I mean the air brakes of the trucks and the whine of all the motorcycle riders who love these curvy roads.
If you want quiet and hiking and have a tent there are a lot of other options in the area. If you are coming with your family and a bunch of kids who need entertaining, this might be the place for you.
