Hello Vicki, From October 1-April 30, we have one cavern tour called the Winter Tour available. It lasts about one hour, and is about 1 mile in length. There are 38 steps to enter, and 60 coming out. Neither sets are overly steep, and both have hand railings. From May 1-September 30 we have two tours available. The Natural Wonder Tour has no steps to enter, and 60 to exit. The Historic Tour has 44 steps to enter and 38 to exit. All of these sets of steps have hand railings as well. While you are in the cavern, there are no big inclines to overcome. A few slight ups and downs with the natural flow of the cavern, but nothing overly difficult. We are sure both you and your grandson would love the cavern, but understand your leeriness. If you have any other questions, please feel free to give us a call at 937-465-4017. Thanks for your question!
They offer 3 different tours. 2 involve stairs,1 is steep stairs,the other are not so steep. They also offer a shorter tour that does not involve stairs. I would call and talk to a tour guide to get their recommendations for you. They are very knowledgeable and nice so they will take the time with you to assess what would be best for you and your grandson.
At the end of the tour during winter months, there are stairs at the beginning of the tour and at the end. The end of the tour takes you to about 60 steps upward.
