This is an honor system, first come first serve. Not a lot of sites here. They do have a store and showers within walking distance though. Some of the sites are really close together with minimal privacy. It was still really quiet after hours and it backs directly up to the Appalachian trail and at least one other hike that we saw. We enjoyed our stay here but would have liked a bit more spread out sites.
We did a drop in on this campground this month and I was amazed that they had availability in July. This campground has a lot of sites but they've spaced them so that they can be pretty private and quiet. If you get in early there a lot of really choice sites. But even the non choice sites are great. Quiet time starts at 10 and is enforced. We didn't hear a soul all night. It is really close to one of the entrances to Skyline drive and really inexpensive at $15 a night. Really close to the Appalachian trail among other hikes and it has a great little camp store. Only down side was a lot of the campsites didn't have grills to put over the fire. We loved this site and will be going back!
