Discover more about Mark Twain Cave

The Mark Twain Cave, originally known as McDowell's Cave, is a captivating show cave near Hannibal, Missouri. Discovered in the winter of 1819-1820 by a local hunter, Jack Simms, it quickly became a popular spot for locals. Samuel Langhorne Clemens, better known as Mark Twain, spent much of his childhood exploring the cave, which later served as inspiration for the famous McDougal's Cave in 'The Adventures of Tom Sawyer'. Today, the Mark Twain Cave stands as Missouri's oldest operating show cave, offering guided tours since 1886. Visitors can traverse the cave's maze-like passages, admire the unique geological formations of Louisiana Lithographic Limestone, and view some of the 250,000 signatures etched into the walls over the decades. Keep an eye out for the signatures of Jesse James and, potentially, Mark Twain himself. The cave maintains a steady 52 degrees Fahrenheit year-round, making it a comfortable destination no matter the season. The Mark Twain Cave Complex also includes the Cameron Cave, a flashlight tour through a natural maze. Other attractions include the Cave Hollow Winery, a campground, and various shops.
