Keep in mind the prices are cheaper when you purchase them ahead of time online. We thought the prices where cheaper on Thursday (it was 5 or 7 days ahead of that day) it showed it at $18. So on Thursday we went online to buy the tickets and they were $24. So if you want the cheaper price you have to buy them ahead of time.
Prices vary depending on what you choose to see while you are there. Here is the link to ticket sales. https://naturalbridgecaverns.com/api/tickets.php
