Mount Grenfell is a rock ridge where erosion of the sandstone created shelters that were occupied by Aboriginal people for around 1,900 years. There are several shelters positioned around a water hole and three contain hundreds of examples of well preserved rock art.
Much of the figures are using red and yellow ochre, however some are white clay and black ash from fires using twig brushes and in some cases finger painting. The most recent images depict examples of Europeans on horse back.
The site includes picnic facilities and toilets.
