Mammoth Cave is a natural time capsule; home to ancient fossil remains of long-extinct giant animals. This huge cave is the most easily accessible of all the show caves in the region, with wheelchair access into the first chamber of the cave. It is a self-guided cave, which you explore on your own while listening to an informative 'audio tour' through the MP3 player and headset provided - available in English, German, Mandarin, French and Malay.
