What You'll Learn

The Naracoorte Caves in South Australia
The limestone in the area was formed from coral and marine creatures around 200 million years ago and again 20 million years ago when the land was below sea level. Groundwater has since dissolved and eroded some of the limestone, creating the caves. The Naracoorte Caves were formed at least 1.34 million years ago and have served as important fossil repositories. The fossil-bearing silt in some areas can be up to 20 metres thick, preserving a wealth of information for future research.
The Naracoorte Caves Conservation Park was redesignated as a national park in 2001 due to its national significance. It is now known as the Naracoorte Caves National Park and offers a range of visitor activities, including show cave tours led by professional interpreters. The park also features the Wonambi Fossil Centre, which showcases fossils and bones discovered in the caves, along with dioramas of extinct animals.
The Blanche Cave and Bat Tour is a popular attraction, where visitors can learn about the critically endangered southern bent-wing bats through infrared camera observations before exploring the Blanche Cave. The Alexandra Cave tour is a 30-minute introductory experience suitable for families with small children, providing an overview of caves and their geological formation processes. The park offers camping, dormitory accommodation, picnic grounds, and a licensed cafe, making it a comprehensive visitor destination.
