About 100 miles south of St. Louis, the Shut-Ins is a natural water playground that owes its existence to a volcanic eruption over a billion years ago. This eruption caused the formation of a hard rhyolite cap, which, over time, was sculpted by the East Fork Black River to create intricate patterns of smooth channels, deep pools, and cascading waterfalls. The result is a stunning labyrinth that is visually appealing and offers unique recreational opportunities.



Visitors are drawn to the park for its natural beauty and the chance to indulge in enjoyable water activities. The pools are of varying depths and sizes, making them suitable for swimmers of all skill levels. From leisurely paddlers to adventurous divers, everyone can have a blast here. The smooth rocks provide natural slides, allowing thrill-seekers to glide along the water’s surface, creating an exhilarating experience unlike any artificial water park. The Shut-Ins is also a great place to visit on hot days because the underground springs keep the water cool. The clear water and scenery make it an ideal destination for people who want to explore the outdoors in comfort.

However, it’s important to know that swimming here can have risks. Be careful of the river’s changing conditions, strong currents, debris, and slippery or unstable bottoms. To stay safe, wear sturdy water shoes and life jackets. There are also rules to follow while enjoying the water, such as not bringing in food, alcohol, or coolers.

Luckily, there’s more than just swimming at this state park. You can stay overnight in one of six comfortable camper cabins or pitch a tent under the stars. There are plenty of trails to explore, either on foot, horseback, or bike. During the summer, there are programs that offer both fun and educational activities.

If you’re planning a group camping trip, you’re in luck, as the park has a fantastic camping area specially designed for larger groups so everyone can enjoy the great outdoors together. For fishing fans, the Black River is the perfect spot to cast your line. Just remember to steer clear of areas where people are swimming. There are also playgrounds near the North Day-Use Area and the campground store, so the kids can have a blast while you relax. And for those up for adventure, the park allows rappelling and rock climbing with a permit during the summer.

A couple of caveats: pets aren’t allowed on the trail to the Shut-Ins. However, there are other spots where you can access the water with your furry friend. Also, before heading out, be sure to check the weather and river levels to make sure you have a safe and enjoyable experience. A flag system will let you know whether the water level is safe for swimming activities. Johnson’s Shut-Ins State Park is an adventure waiting to happen. That said, be sure to add it to your Midwest bucket list.
