Grindstone campground is a large, primitive NF site that will only have a single loop(Opossum) open with no water or electricity for 2021 and the foreseeable future. I spoke with volunteers who stated there are extensive infrastructure needs and no funds to complete the repairs. So, if you have a tent or smaller RV, bring your own drinking water, and enjoy this quiet, wooded campground. There are portable toilets. Some of the site drives are sloped. The dump station is unavailable. For a site without facilities, the price seems a bit steep ($24 for a single,$48 for a double site).
If you have kids, there’s a play area, as well as a basketball and volleyball courts. There is also a small stone pool along the creek. I camped here with friends the weekend we decided to hike Mt Rogers. The trail leaves from the campground with some switchbacks. The summit of Mt Rogers, VA’s high point, is wooded, but there are some open fields and the potential to see wild horses as you approach the final ascent. There are easier trails than this, but you can enjoy relative solitude for most of the trail until you join the madness that is Grayson Highlands with the crowds out for a quick ascent.
