Mark Twain Cave & Campground

4.7 stars. Hannibal is "someone's fading memory of a town," but you can tell it used to be a cool place. The Mark Twain history part of it is cool! The cave is fantastic with history galore and a reasonable price. The gift shop is also very very nice. The people checking you in and running the tours are great and very pleasant. The campground is under a nice canopy of oaks and is in a valley between two hillsides that contain caves. The place is very quiet and has a nice feel to it. The whole campground is gravel except for sites f1 through f12 which have grass and are bordered by a crystal clear rocky creek. Two older and smaller playgrounds, a picnic shelter, laundry, and a couple of community corn hole boards. Highly recommend a site under the trees along the creek in the C or F section. I think f10 is probably the best site. We enjoyed our stay in f2.

First visit to Mark Twain Cave. Entrance takes visitors through the gift shop.

The cave reminded me of slot canyons under ground. There were a few color-lighted features for esthetics, but otherwise, lighting enhanced the cave's natural features.

The tour path was a firm surface and fairly easy to navigate. My 77 year old friend used a walking. stick and had no difficulty.

This tour was definitely worth the time.

We had a wonderful time! The campground was spacious and very clean. Very easy to find right outside of downtown Hannibal. Everyone who works there was fantastic from start to finish. We had a great time exploring Mark Twain Cave while we were there. We will be back in the future!

The Mark Twain cave was amazing! All the different passageways and paths showed all the cool history of the cave. Highly recommend! Our tour guide, Grace, was absolutely amazing! She made hilarious puns and walked us through history. Would definitely go back to explore the other tours they offer there!

Cave is cool to see but coming back years later to show my kids and seeing the crazy prices they charge now is just sad to see. For most people bringing a family will be out of their reach. Which wasn’t the case 15 years ago. $30 per adult is pretty crazy for an attraction that was naturally made, and has very little maintenance. Cool to see once, but at this price, it’s not worth a second trip for a long long time.
