The Naracoorte Caves National Park visitors centre doubles as the impressive Wonambi Fossil Centre – a re-creation of the rainforest that covered this area 200,000 years ago. Follow a ramp down past grunting, life-sized reconstructions of extinct animals, including a marsupial lion, a giant echidna, Diprotodon australis (koala meets grizzly bear), and Megalania prisca – 500kg of bad-ass goanna.
