A good place for RV camping, not so much for tent camping. This is a campground with RVs in mind- large parking pads, tons of sites with hookups, and small green space for tents. No privacy as the trees are along the back of the camping row. Which means there really isn't anywhere for a person to hang a hammock. But, the campground was sparkling clean. The bathrooms were new looking, and shower passes could be purchased for $5 from the camp host if you weren't camping but needed a shower. I guess they have had some boaters from the Meramec River come up and use the facilities. If you are camping on the weekend you do have to pay for two nights (F/S or S/S).

The real draw of this park is the caves. You can tour the main cave from the Visitors Center. $15 will get you a guided 90 minute tour of Onondaga Cave. Afterwards you really should take the hike on Herron Trail to see the original entrance to the cave, which is mostly underwater unless its a really dry season. There is also a second entrance that is gated, so if you want to go in, you have to pay up at the Visitors Center. There is apparently another tour offered for Cathedral Cave, but it wasn't open while I was there. The tour of Onondaga Cave was worth every penny and makes camping here worth it.
