I came across a campground area with picnic tables somewhere north of the Cedar Cliffs area in Virginia a few years ago. I I forgot the name of the spot. It was north of the Wintergreen area, maybe around Dripping Rocks? The Google map shows a looped roadway section near the Greenstone Overlook but there is no indication it is a campground. The Appalachian Trail had one of those stone columns with a crimped metal band indicating the side trail to this campground but alas no data is retrievable in my cyber searches so far.
