Toolbrunup is among the highest peaks in the Stirling Ranges of Australia. The walk to the summit of Toolbrunup is often regarded as the best in the Stirling Ranges. The views from the summit are excellent, the many dramatic rocky outcrops provide spectacular scenery. Toolbrunup is made from sediments deposited during the Ediacaran Period and later metamorphosed to quartzites and shales. These formation rocks were later folded during basement rock movement.
The first European to climb the peak was Ensign Robert Dale who did so in 1832 when he passed through the area. John Septimus Roe did the same three years later and the botanist James Drummond followed in the 1840s and returned several times to collect and identify plants in the area.
