Discover a subterranean world of wonder along Route 66 at Missouri’s famous, seven-level Meramec Caverns. Enjoy guided cave tours, riverboat rides, gold panning, seasonal zip lines, and more!

Meramec Caverns is Missouri’s largest show cave – and that’s saying something in a state with a more than 6,000 surveyed caves. The 4.6-mile cavern system is located in the Ozarks, near Stanton, Missouri.

The cave was well known to natives, with a number of Pre-Columbian Native American artifacts found inside. In fact, it was Osage stories of the cave that led the first European here in the early 1700’s.

Since then, the cave has served as a saltpeter mine, a Union gunpowder facility, heat shelter, party venue, and a movie set. Some even say it was a hideout for Jesse James.

Today, it’s more simply known as Missouri’s biggest and most famous show cave!

Visiting the Caverns

Meramec Caverns were formed over millions of years by the steady erosion of limestone and accretion of minerals. This type of cave is known as a “living cave” because it is still being formed.

Meramec Caverns has around 18 miles of passageways and chambers to explore. The complex of caverns is taller than a 7-story building and decorated with naturally occurring stalactites, stalagmites, and other weird stone shapes.

Guided cave tours are conducted along well-lighted walkways by trained rangers. The 80 minute tour will take you to some of the rarest and largest cave formations in the world. Stone formations in the Wine Room, the Mirror Room, and The Greatest Show Under the Earth, to name but a few, will take your breath away.
