In this episode of Exploring the National Parks, we’re going on a journey deep underground to Mammoth Cave National Park! 

Get ready to explore the world's longest cave system, but be prepared to adjust your expectations as we explain why this cave is more about its sheer size and history than dazzling rock formations. We’re sharing our favorite tours, including one that might feel a little too familiar to Lord of the Rings fans, as well as our hilarious mishaps while navigating tight spots and low ceilings.

Join us as we discuss...

  • Why Mammoth Cave's "subway tunnels" and vast size are more impressive than traditional cave decorations
  • The importance of booking your cave tour reservations in advance to avoid disappointment
  • Our top tour recommendations for first-time visitors, including the "Historic Extended" and "Domes and Dripstones" tours
  • John's hilarious struggles with low ceilings and narrow passageways in sections like "Fat Man's Misery" and "Tall Man's Agony"
  • The fascinating history of Mammoth Cave, including its use as a tuberculosis ward and the role of enslaved African-Americans as early tour guides.

Whether you're a seasoned caving pro or just curious about what lies beneath the surface, we hope these tips will have you ready to explore this spectacular underground world. Just be sure to check how tall you are before you go!
