I have looked into Shenandoah River Raymond "Andy" Guest State Park. It is actually several miles south of Front Royal near Bentonville. Looks interesting, and hope to try it out sometime in the near future.
Gooney Creek is also south of Front Royal on Rt. 340. I have seen it from the road, but have never driven into the campground. Looks rustic.
Mathews Arm on the Skyland Drive is about 15 miles from Front Royal. Again, I have never stayed there, but have stayed at the other 3 campgrounds on the Drive, and always enjoy the stays. No water or electric, though.
