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.

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.

The new additions that came with the expansion are wonderful! The new places to visit are excellent! Do yourself a favor and grab a bite to eat at the Hy-Vee shoppe before you head to the cave! You won't regret it! Miss Bonnie would love to teach you a little about a lot if you stop next door after your meal! She's a real sweetheart.

Great history with a large cave system. Tour guide didn't know much about physical geography. A bit pricey. The older lady selling fudge in the gift shop was nice. Staff helped my daughter track down a necklace she wanted. Fudge was excellent but a bit pricey as well. Bring sweat shirts or jacket.

I loved this beautiful campground. Tucked away in a well maintained cleared space in the surrounding woods. Clean showers and the camp store had everytghing you needed. The campground is right next to a cave tour and even a winery!

Very fun experience! Huge cave, when you get to the middle they turn all the lights out, and it's pitch black. My children loved it!
