Mammoth Cave NP – River Styx Tour & Historic Tour (Extended)

A lot of the River Styx Tour follows the more popular Historic Tour route but it is a very different tour. I liked it much better than the Historic Tour. You get to go to the deepest part of Mammoth Cave (down to the River Styx and Echo Lake). The River Styx tour also was the best tour we went on to understand the geology of the cave system. Our tour guide was great at explaining how the longest cave system on earth was formed. By the time the tour was completed I’d learned enough geology to no longer feel like the entire cave would come crashing down on my head.
