This is one of the coolest places I've camped, easily! There are plenty of spots right along the top of the "wall" that offer views of the land and sunrises that can't be beat. There's a huge cell tower there so service is actually great. Located right outside Badlands National Park and free of charge, this is place is beyond cool. Keep an eye on the weather if you're in a tent or a tall rig though, wind storms can roll in quickly and are incredibly strong (see the cool part about camping on a cliff turn into a potential disaster) so just stay aware. 100% worth it. Also, no toilets so prep for that :).
