We exchanged our Historic Tour which was 2 miles long and included 600 steps for the ADA tour 1/2 mile long and no steps one.
We entered the cave via an elevator into a section of the cave that actually had a cafeteria for visitors ( in the 50’s I believe and they stopped in the 70s)
The guide explained the history of the discovery of the caves, the path to becoming a National Park, some of the key figures for the park and much more.
We learned that 80% of the bat population was killed to an sickness spread from europe and our shoes were sprayed with a soap solution after the tour to prevent the further spread of the disease.
We saw some creepy looking Cavebugs that according to the guide explode if you bring them to the warm surface.( no evidence provided )
