We traveled our way through Tennessee into Kentucky. In Tennessee we were supposed to go to this underground cave river and boat down it in the dark... but since the day before it had rained so much, the water level was too high! Boo! So we drove a bit more and went to Mammoth Cave in Kentucky instead.
So Mammoth was very different from Carlsbad. The path we took inside Mammoth was much more cavelike. We actually had to turn our bodies to squeeze through tight crevices at times and climb steep rocks. It was really dark too, so photos just don't do it justice.
When we showed up, there were only a couple tours left, so this time around we had to go with a guide. Meet Caveman Joe!
We were up at the front of the single file line of about 25 people on the tour, so we got to chat with him quite a bit. At times, we had to wait for the end of the line to catch up with us, so we had time to pose for some pics and look for rare cavebugs in the dark.
Near the end of the tour, we had a chance to go to the "Niagra Falls" area of the cave. It's a wider open space with stairs that you can walk down to see the rock formations that look like very tall waterfalls.
Then it was onto our next Kentucky destination. Turns out you can take all kinds of cool photos with silvery trucks!
