Sephton’s Nek appears to have been named after Thomas Sephton, a British immigrant that arrived in the Zeerust district in 1860. He worked as a prospector and after finding some traces of gold, was partly responsible for starting a sudden rush on what was to become the Malmani Goldfields, today called Ottoshoop. The pass is situated on the tarred R47 route between Zeerust and Kopfontein, which is the primary border post used by most South Africans when travelling by car to Gaborone, the capital of Botswana. Also located along this road is Madikwe, one of the largest game parks in South Africa.
This relatively unknown poort is one of several which follow the north/south course of rivers through the Witwatersberge. It is located 12 km to the south-west of the Hartbeespoort Dam. The drive is generally over easy gradients, but there are several fairly sharp corners and one short, steep climb of 200m in length. The road offers lovely views over the small valley with the river below the road and to the east. This is a gravel road and is generally maintained to a reasonable standard.
Zilkaats Nek is sometimes also spelled as Silkaatsnek. It runs on the NW-SE axis through a low point in the Magaliesberg range and connects Pretoria and its outlying suburbs with Brits. The pass is straightforward with two gentle curves but it is fairly steep near the summit as well as on the south-eastern descent. Although the average gradient presents at a mild 1:36. the steepest gradient is 1:6 which will definitely tax some of the smaller engined cars in the rarified Highveld air.

We are as passionate about maps as we are about mountain passes. A good map is a thing of beauty that can transport you into the mists of time or get your sense of adventure churning. It is a place to make discoveries about deserts and seas, mountains and lakes; of roads leading into places you have not been before; a place to pore over holiday destinations or weekend camping trips. A map is your window to the world.
