The Caverns’ large, connected underground cave system covers over 8,000 linear feet of known surreal cave passages. Underground shows are hosted in a section of The Caverns historically known to locals and cavers as the Big Mouth Cave because of its impressive, large archway entrance. Experts believe humans have been using the cave to escape the heat, take refuge from rain, and enjoy each other's company for up to 25,000 years.

For cave concerts, The Caverns can accommodate 850 people in padded chair seating or up to 1,200 people for standing-room only shows. What’s more, the subterranean concert hall is equipped with state-of-the-art sound and lights, has well-appointed restrooms, and offers delicious food and beverage concessions including craft beer, cider and seltzers. And thanks to the gentle slope of the room and its smooth concrete floor, the venue is accessible to music fans with mobility concerns or physical disabilities.

Daily guided tours include a journey through Big Room Cave, an awe-inspiring underground room which gets its name from its massive size. During the tour, guests learn a little bit about geology, cave lore, and the unique history of Grundy County. Adventure cave tours take guests even deeper inside The Caverns cave system and include the adventurous “Tombstone Pass.”
