Mark Twain Cave Complex

300 Cave Hollow Road

The Mark Twain Cave Complex boasts America's Oldest and Newest Show Caves. Mark Twain Cave is Missouri's first Show Cave. The cave was first shown in 1886 and is a Registered National Natural Landmark.We are located approximately one mile south of Hannibal on Highway 79.

When you visit us you will find a wealth of fun and interesting things to do! We have ample parking and free picnic grounds. We welcome school groups and tour buses.

Experienced guides will escort you on the 55 minute tour of Mark Twain Cave where the walkways are level and smooth, and there are no steps. Because of the natural state of our cave it is not wheelchair accessible. Our cave stays a constant 52 degrees year round! (A light jacket or sweater is recommended on the tours.) Please wear sensible walking shoes.

This place is a cool 52 degrees all the time; which was nice this summer! There are corny jokes on the guided tour, but that's to be expected (I still think they are funny). It is not wheelchair accessible, and I would not recommend it to anyone with mobility issues. There is some neat history here. There seems to be living and dead parts of the cave system. There are very few parts with water at this point. I would've like to hear a little more about development of the cave vs just finding of the cave.

We camped two nights and also toured the Mark Twain Cave. The campground was quiet and very clean. We used one of the pull through full hookups. Everything was exactly as it was expected. The space between campers was slightly tight, and some of the really long class A campers made it a little close getting out of our space. Not a complaint though. The bathrooms/showers were spotless clean. Possible improvement would be a path between the D and E spaces to the bathhouse. Shoes were pretty messy after going across the grass/dirt. Mowers were very courteous to people and vehicles. The cave was amazing from a historical perspective. As we entered we were told that it is a "dry" cave. That was a little disappointing, but our tour guide kept the tour interesting. We were allowed to take photos. I did it with no flash, but others used a flash so I guess that is okay too. The shop is really nice too. All the people there were all pleasant.

We toured the Mark Twain's caves. Very interesting, and our guide an excellent job. Take it light coat, it is 52 degrees inside the cave all year around. If you have any handicaps, this may not be the tour for you because he trails are very narrow and can be slippery. There's also Cameron cave next nearby which we did not go in. Early that is a self-guided tour without any lights, so they give you a lantern to use. Maybe next time!

We are local to the area, decided to take kids to experience the cave, as we did when we were young. My complaint is, at the end of the tour they lead you into a small room with posters of bats and a disease called White Nose Syndrome. There may be no known harm caused to humans, but it's a death sentence to bats. The fungus will never wash out of anything you carry into the cave. I feel like this is something they need to be informing all visitors of BEFORE they decide to purchase $20 tickets. Or taking their small children into the cave. This is a disease still being researched and it is recommended to avoid entering, or wearing protective gear if decide to go in. It should be a choice, not a surprise at the end that you're going to carry a deadly fungus out with you. It will forever be in your clothes, shoes, backpacks, strollers, and anything else you have carried through. This needs to shared!!
