Like its neighbouring pass, Katbakkies Pass, the Peerboomskloof Pass was originally carved out by the local Khoi people as a cattle path. Farmers later used it as a wagon road to cross over the mountains from the Koue Bokkeveld to the Ceres Karoo. Only recently tarred and 4,5 km long, it provides picture-perfect views of the open, rugged expanse of the Tankwa Karoo and the mountain range separating it from the Koue Bokkeveld. 

The first 2 km of the pass are tarred and sports a stiff gradient of 1:7. This tarring was done fairly recently and the road remains narrow with no road markings, so don't be fooled by the tar surface as it is still a dangerous pass. The pass initially enters the bottom end of the poort via an S-bend. The second part of the bend is very sharp and immediately a gravel track leads off to the left which goes to a picnic area. Once the top of the tarred section is reached at 704m ASL, the surface is once again gravel, but the gradient initially remains steep as the road heads up towards the plateau section, whereafter the gradients ease off to a more comfortable 1:20. The upper portion of the pass is relatively easy.
