Mammoth Cave is one of the most well-known landmark features in Kentucky. The cave has a long history within the state and has kept many travelers intrigued by its slightly unusual and captivating caverns, which span 400 miles underground. It's also known as the world's largest cave system, and this, alone, spurs a fascination that is rarely seen with other, smaller caves.

What's perhaps even more peculiar about this cave system is that its above-ground surroundings are just as intriguing. Some tours allow visitors to wind their way through one of many hiking trails that wind through the woodland forests in the region, making for a very full-on adventure. Visitors must sign up for a tour in order to see the caves and trust us when we say it's worth it. Not only will guests be able to navigate the caverns with a pro leading the way, but they'll also gain an interesting insight into the history of Mammoth Cave.

These Tours Of Kentucky's Mammoth Cave Are Worth Taking, Ranked By Difficulty

Mammoth Cave continues to be one of the most fascinating underground cavern systems in the world. While tours are ongoing throughout the year and change according to cave conditions and availability, one thing remains the same: It's entirely worth visiting. We've updated this feature to include relevant information such as tour prices, detailed difficulty levels, walking distance, and any other details one might need to know prior to choosing one. The hope is that this will make planning a future trip easier, and will provide visitors with an idea of what to expect whenever they do.

Frozen Niagara Tour, Domes & Dripstones Tour: Very Easy To Moderate

Both of these tours are ranked as being fairly easy since they don't encompass as many steps as the others. The Frozen Niagara Tour is great for those who are still unsure about how deep they want to go into Mammoth Cave, and it's only a quarter-mile tour. Additionally, this tour is much shorter than the others, taking only about an hour and 15 minutes to complete. Visitors have the option to complete the full 98 steps but are only required to take 12. The shuttle bus takes roughly a half-hour to the site of the tour, and visitors have the chance to see formations in the Frozen Niagara section of the cave as well as the Drapery Room.

Similarly, Domes & Dripstones takes visitors on a limited tour, but this one goes a bit deeper, with a total length of three-quarters of a mile and a time span of two hours. Visitors will see the same cavern sections with the addition of unique formations they'll be walking past as opposed to taking the shuttle straight to Frozen Niagara.

Included are stops at Mammoth Dome, Bottomless Pit, Fat Man's Misery (squeezing in tight spaces required), Tall Man's Misery (crouching required), and some saltpeter mines. A 200-year history will be discussed throughout the tour, and it's by far one of the most beginner-friendly treks offered by the cave.

Grand Avenue Tour: Moderate To Difficult

The Grand Avenue Tour comes in at a moderate ranking because it is four hours long, and covers a distance of four miles. There are bathroom stops included on this tour, and, along the way, visitors will see Cleveland Avenue, Boone Avenue, Kentucky Avenue, and Mt.
