We stayed here the night before our cavern tour. Camping included the out of state vehicle charge which was nice. It’s 28 for out of state cars, 14 for in state. There are also senior discounts. There were some specific regulations as far as what site you could pick and how many tents etc that you could put up. We don’t know how strict they are with it, but make sure your read the signs at the fee area. Sites are spread out but not private, our neighbors were seated looking straight at us, but we couldn’t blame them since there weren’t many good ways to sit without looking at someone. Good for RVs, maybe less so for tents and vans in our opinion. Bathrooms were clean though and everything seemed nicely maintained. Caverns were very cool, but were in limited groups and the tour was shortened because of covid. Still cool though, would have liked to stay when a full tour could have been done.
