Explore an Australian natural time capsule at the Mammoth Cave, home to ancient fossil remains of long-extinct giant animals and the most easily accessible of all the show caves in the Margaret River region. Pick up your MP3 self-guided audio tour to get started, available in multiple languages.

Enter the cave through bushland via a gently sloping boardwalk. Learn about the 10,000 fossils that had at one time accumulated inside the cave. Upon excavating many of these were found to be remains of giant species that became extinct around 46,000 years ago.

See a 50,000-year-old “zygomaturus” jawbone embedded in the cave wall. Complete your tour with a winding walk through the beautiful Marri forest, with whistling birds and stunning flora displays.
