Closed Thanksgiving Day, Christmas Eve and Christmas Day. https://linktr.ee/Cumberand_Caverns We invite you to Discover Cumberland Caverns, the LONGEST show cave in Tennessee! With more than 27 miles of underground passageways, underground waterfalls, huge rooms like the Hall of the Mountain King where you will climb a mountain INSIDE a mountain, an iconic chandelier handing above our World-Famous Volcano Room, and tales steeped in our history of exploration and natural sciences, we are sure to have an experience perfect for you! We have FOUR walking tour options, appropriate for the whole family! If you are looking for something a little more adventurous, check out our FOUR Adventure Tour options! Looking for activities for groups? Check out our FOUR different Overnight Adventure Packages! You can book your tour online 24/7 at CumberlandCaverns.com We are open 7 days a week ALL YEAR LONG, only closing on Thanksgiving, Christmas Eve and Christmas Day. RAIN OR SHINE, it is always cave time. The cave is naturally 56*F year round, and is high up in the mountain so it never floods. As long as the roads are clear, tours are here!
