Mammoth Cave

Our last national park stop … Mammoth Cave, Kentucky.  This is the largest cave system in the world.  We took the Grand Avenue tour of it this morning and walked 4 miles.  Underground.  And there is still PLENTY MORE to see.   Thankfully there were restrooms  behind the rocks and we got to see a rock didn’t fall in place, but was stood up (no date).   We passed Frozen Niagara, saw Domes and Dripstones, and the Snowball room.  There were hundreds of stairs, steep hill climbs, long passages and tight squeezes.  Pretty cool.  We wrapped up the day at the campground – our last night of camping, too!  Fun times.
