The Grampians were first settled by Aboriginals 5,000 years ago, which by Aboriginal standards is quite recent when compared to areas in northern Australia that were first settled 35,000-50,000 years ago. The Aborigines called the mountains the Gariwerd mountains and it became the heart of the Aboriginal culture in Victoria. The region has the largest number of rock art sites in southern Australia – more than 80 per cent of Victoria's rock art sites. Approximately 60 art sites, containing more than 4,000 different motifs have been identified in the national park.
Five shelters are open to the public and are all easily accessible: Manja and Billimina shelters in the Western Grampians, Ngamadjidj and Gulgurn Manja shelters in the north and, one of the most important sites in Victoria, Bunjil's shelter, near Stawell. We visited the Bunjil’s shelter on our way back from Halls Gap to Melbourne.
