A trip to the Limestone Coast wouldn't be complete without a visit to the Naracoorte Caves - the SA World Heritage Fossil Mammal Site. We did a guided tour of the Alexandra Cave which has some great examples of stalagmites and stalactites. Some dripped at a rate of one drop every 5 seconds so a stalagmite grew very quickly and others were only one drop every 90 minutes so they remained a stalactite.

This is the entrance to the Wet Cave which means that at one stage the sea was running through carving out the cave millions of years ago. Many fossils can be found in all the caves - shells, bones & fauna. The caves provide a rare insight into Australia's past, showcasing world renowned fossil deposits. They have found a Diprotodon Optatum - Australia's largest ever marsupial that roamed the area until some 50,000 years ago.

Another part of the Wet Cave showing the limestone formations that have occurred over time. This is a self guided tour but there are a few others that you can take with a guide where you have to get down on your hands and knees and even your belly in some areas to get through. We had to beg 'lack of time' to get out of that one!!! One cave has been used for a production of Macbeth because of its acoustics.
