This very long pass of 26,3 km essentially is more of a poort than a pass as it faithfully follows the course of the Broederstroom (Brother's Stream) as it cascades down the kloof losing 463m of altitude. The average gradient of 1:59 is mild and regardless of whether you are ascending or descending this pass, you will find the change in altitude gradual. It has 33 bends, corners and curves but none of them are significantly dangerous or sharp.

The road is a farming road that forms a long crescent shape to the east of the N9 national road starting and ending at different points on the N9. The bulk of the pass falls within the borders of the farm, officially named Erasmuskloof 259 and this is obviously where the pass takes it's name from.

The pass is regularly maintained and despite the gravel surface is suitable for all traffic. This is mainly due to the arid climate where lack of rainfall ensures the roads remain in good condition.

We have not physically driven this pass ourselves as yet, so our description and research is based on available resources and government maps.
