How to Get There

Archaeological Finds at Mammoth Cave
It’s not just the striking topography that draws the crowds to Mammoth Cave. The cave hit headlines in the early 1900s when archaeologists uncovered the fossilized remains of ancient Australian megafauna, including Tasmanian tigers and giant kangaroos, that have been extinct for thousands of years.
