    Johnson's Shut-Ins State Park is one of Missouri's most popular and unique outdoor destinations. Most visitors come to swim and climb in the namesake shut-ins along the Black River. The creation of the shut-ins began more than a billion years ago with strong volcanic eruptions. Today, that cooled volcanic rock protrudes from river bed creating an area with hundreds of waterfalls, chutes and deep pools for swimming. The volcanic rocks are smooth and slippery, so water shoes are a must for safe climbing. For those who prefer to see the beauty of the shut-ins but not swim, there is a walkway to an observation area above the river.

    Johnson's Shut-Ins State Park also offers overnight camping for both tents and RVs, picnic areas for day visitors, and a three-mile hiking trail. There is also a visitors center and a general store. The main gates to the park open daily at 8 a.m. On the busiest days (weekends in the summer) the park can reach its capacity and there will be a line to get in. It's best to arrive early to ensure you get a spot.

    Johnson's Shut-Ins State Park is located along Highway N near Lesterville, Missouri. It's about a two-hour drive from downtown St. Louis.

    Mastodon State Historic Site in Jefferson County offers a history lesson with your outdoor adventure. The 431-acre park is known for its fossils of mastodons and other ice age animals that lived more than 10,000 years ago. The fossils were discovered in the 1800s and excavations have been underway ever since. Visitors can hike the half-mile Wildflower Trail to the area where most of the bones have been discovered.
