In a shallow recess of a low cliff in the Bilpin area is a panel of Aboriginal rock art, with multiple hand stencils.
There are at least five red ochre hand stencils, although some are hard to see.
Nearby is another cave which is likely to have been an occupation shelter.
There is no rock art in this site, but a large boulder within the cave has what appears to be man-made grooves.
Above both these sites is a deep spear-grinding groove.
