Caves and shelters are located in various places along the Georges River, which over the years have eroded into the sandstone cliffs. There is a large cave located in Peakhurst with its ceiling blackened from smoke. There are caves located around Evatt Park, Lugarno with oyster shells ground into the cave floor. A cave has also been discovered near a Baptist church in Lugarno, and another near Margaret Crescent, Lugarno (now destroyed by development), which was found to contain ochre and a spearhead on the floor of the cave when it was excavated. Another cave exists on Mickey's Point, Padstow, which was named after a local Gweagal man.
