Welcome To Mark Twain Cave Complex

The Mark Twain Cave Complex boasts Missouri’s oldest show cave and one of the newest show caves in the state.

Mark Twain Cave is Missouri’s first show cave.  The first organized guided tour was in 1886.  We proudly became a National Natural Landmark in 1972.  We are located approximately one mile south of Hannibal on scenic Highway 79. In 2019, during our bicentennial year, we at long last discovered Samuel Clemens’s signature in the cave!

Your first stop will be at our main Gift Shop where you will purchase your tickets, souvenirs, books and gather any information you may need and begin your tour.  Included in your tour, you’ll enjoy a 7 minute introductory video covering the cave’s formation and how the cave inspired the writings of Mark Twain.  Our experienced guides will escort you on a 60 minute tour of the cave where the walkways are smooth and there are no steps. The cave is not wheelchair accessible due to its natural state.

Our cave stays a constant 52 degrees year round! We also suggest sensible walking shoes.

Cameron Cave is a 1 hour and 30 minute flashlight tour open from April through October. A professional guide will navigate the maze-like layout of the cave with you, as you explore and experience a cave preserved in its natural state just as it was discovered in 1925.

Next door is Cave Hollow West Winery where you’ll find Missouri-made wines all made from Missouri grapes with exclusive labels only found on the complex. An outdoor sluice where you can pan for gemstones and a campground with nearly 100 campsites will also help create a fun outdoor adventure the whole family can enjoy!

Welcome to the Mark Twain Cave Complex!  We hope you enjoy your adventure with us!
