Notable features include Toolbrunup, Bluff Knoll – the tallest peak in the southwestern region – and a silhouette called The Sleeping Princess which is visible from the Porongurup Range.

The traditional owners are the Mineng and Koreng groups[5] of the Noongar peoples who have inhabited the region for tens of thousands of years.

The women gathered seeds, roots and fruit while men hunted kangaroos and other animals.

John Forrest climbed Toolbrunup in 1881 with Henry Samuel Ranford and made a cairn at the summit.
