Know before you go

After entering the National Park, it will take a few minutes to get to the Mammoth Cave National Park Visitor Center where the Cave Tours start. Try to give yourself no less than 30 minutes from when you enter the National park till when your tour is scheduled to start.

This should give you enough time to get to the Visitor Center, find parking, get your physical tickets, use the restroom and get to your meeting point.

  1. Tickets – You must have a ticket to enter the cave. Try to purchase tickets online and in advance.  During the tourist season, tours are known to sell out.  If you did not get a chance to get tickets in advance you can still check availability in person. I will go more in depth on tour options further down this post.
  2. Time – Hours vary per tour.  Most tours take about an hour. Times that are available for tour vary per tour, season and month. There is not a set clear schedule since tour availability depends on the season. When you book (there will be links below), you will get all the time options.  
  3. Parking – Free parking is available outside the Visitor’s Center. There is room for campers and vans. 
  4. Where to meet/go – When you enter the Visitor Center go straight to the ticket counter to get your physical tickets. Cave tours meet outside under either shelter A or B, the person at the ticket counter will tell you which shelter to meet at. To get to the shelters, go through the doors at the left side of the gift shop. Be there at least 5 minutes before your tour time. If you get out there early enough you can go through the outdoor gift shop or grab a snack. 
  5. Clothing/Shoes/Backpack/Purse – Mammoth cave temperature stays about 50-54 degrees and is damp and wet. Because of this, you will want to wear a light jacket, possibly with a hood since caves tend to drip. Good walking shoes will come in handy for the stairs as well as keeping up with the tour group (it can more at a pretty brisk pace). You can wear a front pack but no front child backpack carriers are allowed. Strollers, tripods/monopods, walking sticks (other than a cane) or metal framed backpacks are not allowed. Backpacks must not be larger than your back.
  6. Food/Picnic – There is no food or drink allowed in the cave. There is also no restaurant on the grounds but there are snacks and drinks.  Tables are available near the parking lot for picnics. 
  7. Pets – No pets, other than service animals, are permitted in the caves or park buildings.  Pets may be day boarded at the Lodge at Mammoth Cave. Proof of vaccination is required.  
  8. Accessibility – A handicap tour is available using the Elevator Entrance. For those deaf or hard of hearing you can make arrangements for assisted listening devices and/or a sign language interpreter.  On the Accessible Tour, wheelchairs, scooters and other assistive devices are allowed. Accessible restrooms are also available as well. The cave does not provide scooters/wheelchairs, if you need assistance you must bring your own. This is a 2 hour tour covering a half mile. Check with the Visitor Center the day of your visit for availability.
  9. Babies – Changing tables are available.  Strollers/wagons cannot be taken into the cave. 
  10. Stairs – Some tours have MANY stairs. If stairs are an issue be sure to pay attention to which tour you choose. Tour descriptions will list out exactly how many stairs you will have to climb. There are a few benches throughout the cave if you need a quick rest.  
  11. Obstacles – Besides the stairs, during the Historic tour there is an area where you will walk down stairs and have to duck under a rock at the same time. Through “Fat Mans Misery” you will walk through a tight passage.  Be sure to read carefully if obstacles are a concern.
  12. Restrooms – Restrooms are located in the visitor center and you can find porta-potties outside near the parking lot. There is a bathroom inside the cave about halfway through the Historic Tour.  Though bathrooms are not available on all tours so be sure to check if this is a concern.
  13. Bikes – Bike racks can be found outside of the visitor center since the park is very bike friendly. You can read more about biking below.
  14. Guns – Firearms are prohibited by Federal law. 
  15. Smoking – Smoking is prohibited, and vaping is NOT permitted in the cave.

Mammoth Cave History

Prehistoric

The story of Mammoth Cave National Park begins millions of years ago, in the prehistoric seas of the Mississippian Era. Around 325 million years BCE, these ancient seas deposited layers of limestone deep beneath the Earth’s surface in what would eventually become the state of Kentucky. 

Fast forward to 10 million years BCE. Rainwater begins a subtle yet transformative process, dissolving the limestone and carving the first passages of what would become known as Mammoth Cave. 

Historic

In the 1790s, John Houchin, a bear hunter, stumbled upon the entrance to Mammoth Cave. This accidental discovery was the spark that would ignite a historical chain of events that eventually led to the cave’s fame. 

The 1800s saw Mammoth Cave serve a variety of roles. It was mined for saltpeter, a vital component in gunpowder production, during the early 1800s. The profitability of this enterprise came at a steep cost in terms of danger and health. As a result, mining operations in Mammoth Cave were both lucrative and treacherous. 

By the 1810s, Mammoth Cave was gaining recognition as a tourist destination. Its mysterious beauty and geological wonders drew visitors from near and far, establishing the cave as an attraction of regional significance. 

The 1820s brought an interesting twist when Mammoth Cave was utilized as a tuberculosis sanatorium. Doctors of the time believed that the cave’s unique environment could offer relief to those suffering from the disease. However, this endeavor ultimately proved unsuccessful, and the sanatorium closed in 1910. 

One of the most notable chapters in the cave’s history unfolded in the 1830s when Stephen Bishop, an enslaved man, became a famous cave guide. His knowledge and storytelling skills enriched the visitor experience and his legacy is still celebrated today. 

In the early 1900s, Max Kämper added to our understanding of the cave system by creating a comprehensive map, shedding light on the vast underground network. 

In 1926, Congress passed an Act to accept lands donated for the establishment of a national park. This marked the official beginning of Mammoth Cave National Park, which was formally established in 1941, making it a protected sanctuary for future generations to enjoy.
