About this activity

Did you know that you can have SHOW caves? You certainly can in Missouri! The Mark Twain Cave Complex actually has the country's oldest AND newest show cave - because it's the FIRST show cave!

Since 1866 families from all over the country have visited to experience these magical feats of nature. Your 55 minute adventure will see an experienced guide (who is wiling to answer any questions you may have!) take you through the Mark Twain Cave filled with smooth and level walkways, which means there aren't any steps!

The caves stays a lovely 52 degrees all year round, so no matter what the weather you know what you're expecting!

55 minute tour to fill a family day out? We wouldn't leave it at that! In the Mark Twain Cave Complex there is also the Cameron Cave, which takes you on an 80 minute experience through the caves that were discovered in 1925. The guides will be carrying lanterns, which will give the experience a whole new light (literally!)

Have the kids been inspired and excited by the idea of all those sparkly gems and formations? They can try and find their own with Sticks, Stones and Bones - and a sluice! Want to know what that is? That means kids of ANY age can pan for semi-precious gemstones of their own! There is also a lovely general store where you can find some lovely local produce.

Nice little keepsakes from your experience! If you wanted to extend your family day out to something longer, there is also a campground where you can set yourself up for a weekend.

Underground fun at Mark Twain Caves! An underground adventure for the whole family!
