Hannibal - 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.

Definitely worth the money and time. The staff here are very friendly and knowledgeable. They really seem like they enjoy the history of the place! If you're a very large person- don't do the cave tour.. There are some spots you won't be able to fit through. The winery was cool too! Some really great local made wine we decided to try and buy before the tour started. The gift shop has everything! Plenty of parking and I could only imagine that the campgrounds are just as cool.

Cave was super cool and the tour guides were very engaging and knowledgeable go through both caves if you can. The mark Twain cave was easy to walk and could be done by almost anyone who walks on their own I imagine. Bring a flashlight to look down all of the caverns and see what nature has created.

Beautiful place. We took the Mark Twain cave tour. Our guide was knowledgeable and fun. It was beautiful inside the caves and a little spooky but lots of fun.

We mostly stay at KOAs but decided to stay where we were close to everything. Had a big storm and didn't lose power like we have at other campgrounds. Dog friendly which is a big plus for us. We had paid for a pull-through but had a massive tree in our spot, so we weren't actually able to pull through. Luckily most people had cleared out and we were able to back out. When we said something about the tree and not really being a pull through site the woman working in the office looked at us like we had horns growing out of our heads and told us to just back up then. The spots are affordable but everything else is priced like you're at Disney, about 3-4 times what it's worth or you'd expect to pay. Bathrooms were slightly nicer than average for a campground.

We toured the cave and loved it! Our guide Darius was engaging and fun, but also provided a wealth of information on everything from Mark Twain to geology and the health of the bats in the area. A fantastic morning diversion in midwinter!
