The Humps

The Humps is a granite rock formation known as a "stepped bornhardt inselberg". It is located within The Humps Nature Reserve approximately 295 km east of Perth and 17 km north east of Hyden in the eastern wheatbelt region of Western Australia.

Rising about 80 m above the surrounding plains, The Humps is one of numerous rock formations in the area. Approximately 15 km to its south is Hyden Rock whose northern side features the Wave Rock formation. Also in the area are Scrivener Rocks and Camel Peaks roughly 13 km west of The Humps, Anderson Rocks about 19 km north, and King Rocks approximately 18 km east of The Humps.

Mulka's Cave


On the north-eastern edge of The Humps is Mulka's Cave, also known as Bate's Cave. The cave contains Aboriginal rock art comprising over 450 hand prints and images. Most sites of Aboriginal art in the region contain fewer than 30 motifs. While visitation has damaged the site, mitigation strategies put into place appear to have arrested further damage. Mulka's Cave is protected under the Aboriginal Heritage Act. It is also both a Protected Area and listed on the Register of the National Estate.

Walks
The Humps Nature Reserve has two marked walking trails. Gnamma Trail is approximately 1220 m long over flat terrain. In contrast, Kalari Trail is approximately 1670 m long and ascends to the summit, and permits focus on the geology and vegetation along the way.

Reservoir
Water run-off from The Humps is directed into the Hyden Humps Dam reservoir. The reservoir is situated approximately 200 m south of The Humps.
