The Naracoorte Caves are part of the 800,000 year old Naracoorte East Range. There are 26 known caves in the park, many of them containing spectacular stalactites and stalagmites.
The caves have acted as pitfall traps and predator dens for over 500,000 years, preserving a rich fossil record of ancient animals that roamed the area. The fossil record covers several ice ages and the arrival of humans in the area.
Palaeontologists have excavated and dated many of the fossils in Naracoorte Caves and have reconstructed the skeletons of a number of the megafauna that inhabited the area so many years ago.
