The Humps

The Humps Nature Reserve is home to a unique granite rock formation called "stepped bornhardt inselberg", with an elevation of approximately 80 metres above the surrounding plains.

It is located 295 kilometres east of Perth and 17 kilometres north east of Hyden in the eastern wheatbelt region of Western Australia. Other nearby rock formations include Scrivener Rocks and Camel Peaks to the west, Anderson Rocks to the north, and King Rocks to the east.

Mulka's Cave, also known as Bate's Cave, is situated on the northeastern edge of The Humps. It contains over 450 handprints and images of Aboriginal rock art, making it a site with fifteen times more art than most in the region. Although there has been some minor damage from visitation, mitigation strategies have been implemented to prevent further harm. Mulka's Cave is protected under the Aboriginal Heritage Act and is both a Protected Area and listed on the Register of the National Estate.

The Humps Nature Reserve offers two marked walking trails. The Gnamma Trail covers approximately 1,220 metres of flat terrain, while the Kalari Trail is about 1,670 metres long and ascends to the summit. Visitors on the Kalari Trail can observe the geology and vegetation along the way.

The Hyden Humps Dam Reservoir is located about 200 metres south of The Humps. It receives water run-off from the rock formation, making it a significant body of water.
