Welcome to Big Mike's Rock & GIFT SHOP
We specialize in high-end rocks and old-fashioned fun!
Our world-class rock and fossil specimens will thrill the most seasoned collector – or help a first-time buyer assemble the perfect selection of must-have minerals.
You can pose with our giant Mosasaurus roadside attraction outside and view the REAL "Big Mo" Mosasaurus skull inside before touring our Mystery House - a definite throwback and a wonky wormhole of fun for the whole family!*
In addition to visiting the Rock Shop and attractions, stop into the gift shop* to discover kooky oddities and Mammoth Cave souvenirs at affordable prices - including pick-your-own geodes!
