Meramec State Park

With more than forty caves, Meramec is riddled with the kind of underground world that makes Missouri the Cave State. Most are left wild and closed to protect the bats and formations inside, but one, Fisher Cave, is open to the public on guided tours in the warmer months. It is a memorable one: a passage of tall calcite crystal deposits and thirty-foot columns, with claw marks left on the walls by bears that denned here long ago, all shaped by water over an immense stretch of time.

Because a park guide leads every Fisher Cave tour, the visit comes with the story of how the cave formed and who used it across the centuries. The tour is a walk rather than a crawl, but the cave stays cool and a little damp, so a light layer and shoes with grip make it more comfortable. It is one of the best cave experiences on this stretch of Route 66, and one of the reasons the park draws visitors back.

Above ground, the Meramec River is the heart of the park. Clear and gentle over most of the summer, it is a favorite for canoeing, tubing, and swimming, and outfitters near the park rent boats when the water is right. Gravel bars make good spots to pull over and picnic, and the river's slow bends give an easy, unhurried float suited to families and first-timers.

For those who would rather stay dry, more than a dozen miles of trail climb through the forest and out onto the bluffs. The Bluff View Trail is the popular one, a walk to the edge of high dolomite cliffs with sweeping views over the river valley below, while the longer Wilderness Trail runs deeper into the backcountry past caves, springs, and quiet woods. Between water and trail, the park easily fills a full day in any warm-weather month.

The park lies just off Interstate 44 near Sullivan, simple to reach and simple to combine with the Route 66 towns nearby. The grounds, trails, and river access are free, while Fisher Cave tours carry a modest fee like other Missouri state park caves. Tours run mainly from spring into fall and can fill on busy weekends, so it pays to check the schedule and aim for a tour time when you arrive.

Start at the visitor center for maps and a look at the park's caves and history, then decide whether the day leans toward the river, the trails, the cave, or all three. Bring water, sun protection for the open bluffs, and a layer for the cave. It is a big, generous park with something for every kind of traveler, from a lazy afternoon float to a real hike, all set in the kind of Ozark river country that makes the drive worth slowing down for.
