[1] Although an earlier rough track existed in a similar route, the Kalamunda-Mundaring road was developed in the late 1930s.

[2][3][4][5] It is the primary access route for Mundaring Weir, a dam and tourist attraction.

[6] It passes east of the Beelu National Park, and north of Mount Gunjin.

It starts from Phillips Road in Mundaring, 35 km east of Perth's central business district, and heads south towards the weir from which it derives its name through State Forest regions.

It then heads west, providing access to the sparsely populated and largely forested agricultural localities of Hacketts Gully and Paulls Valley, before entering Kalamunda from the east.
