Spent two nights here right at the edge of the official "Cosmic Campground" simply because the restrooms are nearby. But if you have a decently high clearance and don't mind being jostled around a bit if you don't drive slowly, you can get to other campsites marked by fire pits. As the name suggests, it's super dark. If you don't have a red headlamp, save a picture of a bright red color, use it as your lock screen, and turn the brightness up. It'll save your night vision.
