Neat cave! Has an interesting history. The underground Lakes were incredible! Great experience. Stairs can be tricky since the are wet and not uniform but as long as you take your time they aren't a problem. We like the walked way over the lake! Very unique!!!!!
Definitely worth the stop if you’re nearby, the caves were beautiful! Unfortunately our guide was extremely new and didn’t have as much information on the history of everything as we would’ve wanted. Still very glad we went and got to experience the beauty!
