The Appalachian foothills in Kentucky are pretty geologically dead; there aren’t any fault lines anywhere close by. It’s about as safe as any cave network can be.

I do recommend going to that are and taking some tours, especially in the middle of summer where you can see the inversion layer where the air goes from being 95F to 60F. Even the fully-accessible tours that don’t go through any tight spaces are pretty cool.
