This is a private campground run by Meramec Caverns. The campground is large and shaded, right on the river. There are hook up sites and tent sites. My advice is to try and get a spot all the way to the left of the entrance. These sites seem quieter and more spread out. The down side is that they are pretty far from the shower house and bathrooms. Most of this sites (but not all) have picnic tables, grills and fire pits. There are a few really nice sites right on the river. There is a restaurant, general store, canoe rental, zip line (it goes across the Meramec River, not sure how you get back!), and of course the caverns. The cave tour is a bit hokey, but if you can look past the mannequins and silliness, the caves themselves are really spectacular. You can definitely see why Jesse and Frank James used this as a hideout.
