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.

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 spent two days this October at MW Campground. It is a nice facility with a helpful and friendly staff. The setting in a valley is nice. Lots of trees. A little bit of horn noise from the nearby rail line but not bad at all. Easy drive to Hannibal. Our site had a walnut tree which littered the site with walnut balls and created some surprising "thumps" as they hit the roof of our camper from time to time.

I want to highly recommend the Mark Twain impersonator that the cave and campground hosts. He takes you back in time and remind you of why Mark Twain had such international acclaim. We heard him on my dad's birthday and enjoyed the experience.

It's a very beautiful camp ground. The bathrooms are fairly clean and the staff are very polite. The camp sites are uneven and have gravel areas to park. It is a far better place for a tailor or camper. We tent camp and had to move spots in order to set the tent up. The staff were very accommodating, however. I really enjoyed how close to town the campground is. It is very convenient.

Very good tour. Our guide was knowledgeable and provided plenty of history and stories about this cave system. Great for everyone.
