I have mixed feelings about this experience. J-Shuts never gets old and I gave been visiting for over 20 years, but only camped once in July. The newish (9 yrs old?) is the result of the old sites being washed out when the Ameren Reservoir breached flooding and destroying much of the campsite area. The decision to move camping across Hwy N is good for safety, but separates you from the shut-ins which is probably why you are there. We had a site with electric hook up which meant we could charge phones and run a small fan to combat Missouri heat. We tent camped but our site was clearly meant for a camper. There was only a small patch of rocky grass and a large concrete slab and pull through. It backed to trees, but was mostly unshaded and completely exposed to the road. The showers and restrooms are individual, good sized closets. No charge for showers. There is a store that has what you forgot, plus fun stuff you didn't know you had to have until you saw it.
There is so much to see in this area of Missouri. This campground is a great jumping off point for seeing not only the Shut-Ins, but Elephant Rocks, Taum Sauk State Park, hiking the Ozark Trail, and checking out the town of Arcadia Valley.
