Common Questions

  •    Can my group do this?
    Families & Individuals Only
    The cave trail is for families and individuals, those NOT receiving group rates.

  •    Does the offer expire?
    By 12/31/2020
    You have through December of the current year to finish visiting all four show caves and earn your free shirt.

  •    Can I see all 4 in one day?
    No Way
    It would be impossible to tour all four caves in one day. Why rush? Take the weekend or a full year. It's easy to see two caves in one day and have a great get-a-way in Southern Indiana.

  •    Where do I get my passport?
    At Any Cave
    The first cave you visit will provide your passport. There is 1 spot for each cave. Each person needs their own passport.
