There are many different tours to choose from.  The violet lantern tour included a visit to a hospital that had been located in the cave many years ago to treat tuberculosis patients.  At that time, they hoped that a cool, damp environment would cure the disease; before later discovering the opposite - - a dry and hot area is a more effective treatment.  We also saw early markings of native American tribes of centuries ago.

One of the most interesting aspects of the tour was a cavern where a Methodist church used to meet for services to enjoy the great acoustics.  When traveling through central Kentucky, consider touring this wondrous park.
