Such a great day trip in North Alabama. The caverns are stunning. The tours are guided and there are lots and lots of stairs so this isn’t for the weak or weary. If you can handle a haul, a climb and a couple tight squeezes this is just for you. They have a very nice gift shop with lots of great gemstones and rocks and books along with toys and snacks . There is a mining for gems trough which is always fun and also a swimming area. Bathrooms are typical park restrooms so not luxury but in line with other park facilities. It’s a great place to visit and if you’re near you must stop by if you have the chance.
