Closest... to where? You forgot to tell us.
Look on a geology map to locate the limestone-bearing area nearest to your reference area (your home or wherever else you mean).
Then try to find out if there are any show-caves in that limestone area - that's the easiest start because you can find that from tourist information, but it's not infallible. My nearest caves are within 10 miles of my home but none are show-caves!
Better perhaps, try finding a caving web-site - the most useful would be to search for caving or karstareas in your country or administrative region.
I'm not able to provide real-time information on the closest caverns to you. I recommend checking a local search engine or asking for recommendations from locals in your area to find the nearest caverns to visit.
