Can't beat the price
This campground is free as in beer. No pay stations or anything. There are practically no amenities: just vault toilets and no potable water anywhere, so make sure to bring plenty of drinking water. Other than that, this place is great! Easily worth some money. The campsites are nicely laid out, and there's a creek nearby. It's not deep enough for swimming, but it's perfect for a refreshing wade. The trailhead for Pam's Grotto is right across the road, and certainly worth a visit.
Only downside I encountered here was a family a few campsites over who ran a generator all night. Pretty dang annoying.
