What to Bring for the Tour
  • Warm clothing. The cave is 44 degrees Fahrenheit (7 degrees Celsius) year round, the temperature of your refrigerator!
  • Good walking shoes. Please do not wear open-toed shoes, flip-flops or sandals without a supportive strap because the trail surface is uneven, slippery, and wet.
  • Optional: camera. Cameras must be on a strap or be able to slip easily into a pocket. Avoid cameras that are carried loose because they can easily be dropped in the cave. Taking pictures with flash is allowed in most areas of the cave but your ranger will ask you not to take photographs in areas where bats are known to roost. Taking pictures of sleeping bats can disturb them and possibly cause serious harm to them.
 
These items are not permitted in the cave.

What NOT to Bring for the Tour

  • Flashlights. The cave is lit and rangers carry flashlights.
  • Backpacks, large purses and tripods. These are not permitted in the cave due to low ceilings and narrow passageways. Leave them in your car or check them in at the visitor center.
  • Anything worn or used in a cave or mine east of the Rocky Mountains or a cave or mine in Europe. As of March 2011, this measure is in place to prevent the spread of the fungus linked to white-nose syndrome, a fatal disease in bats.
  • Your pet. If you can, leave your pets at home. If you are traveling with your pet, bear in mind that the shade will move while you are inside the cave, and shade is limited.

Did You Know?

Debugged-DYK

Computer bugs, slang for something gone wrong in a program, are actually named for a real insect. In 1947, technicians working for computer scientist Grace Hopper found a moth inside her computer. The trapped moth was making the machine malfunction. Once removed, they reported that the computer was “debugged”. They taped it onto her notes with a little joke that is now part of our everyday language.
