These beautiful ancient cave formations in Cave Hill Country Park lay inside the largest and highest granite outcrops in the region. The caves are home to indigenous cave paintings that tell the Dreamtime creation story of the Seven Sisters. The route bypasses the cave however, if you have time, it's definitely worth stepping inside and exploring.

Napolean's Nose is a cliff-edge that is said to resemble the profile of the famous emperor Napolean. See if you can spot the similiarity as you jog by.
