Great little place for some weekend camping. The organized group site DOES NOT have facilities or showers (just porta potties) HOWEVER there are comfortable showers and proper bathrooms around the visitors center just about a half hour away.
Bring bottled water, no water spigot at organized camp sites (water available at visitor center if you bring water containers)
Bring your own fire wood as well; although there is a camp store, again near the visitor center about a half mile up the road.
There's a dollar general and a small grocery store about 10 minute drive away, if you forgot something and need to pick it up.
Beautiful little place, with a lot of natural sight seeing near by, decent signage to help you get around. There are hiking trails, fishing, waterfalls near enough by car.
