The Stirling Ranges are popular for some of the best mountain walks in Western Australia. Bluff Knoll is the highest peak at 1096m. Other peaks are Tollbrunup at 1052m, Ellen at 1012m, Mt Trio at 856m, Mt Hassel at 847m, Mt Magog at 856m and Talyuberlup Peak at 783m. The Stirlings cover an area of 1100 sq kms – 64km long to 18km wide.
The Stirling Range National Park is just south of Gnowangerup. The range of mountains was first discovered in 1802 by Captain Matthew Flinders who was visiting the southern coast on the HMS Investigator but was not named until 1935 by John Septimus Row after Capt James Stirling. Stirling was the first Govenor of Western Australia.
