The Karoo Poort is a very old route followed by the first settlers, and together with the Hottentots Kloof, formed the only route to the north (and the Karoo) from Cape Town through Ceres. The road is a typical poort, with easy gradients, following the course of a (mainly dry) river-bed through a natural gap in the mountains. The construction was managed by Andrew Bain and built by Adam de Smidt, who would later become Andrew Bain's son-in-law and Thomas Bain's brother in law. The pass is gravel, except for a small section of just over a kilometer and a half, where the tarring was no doubt done to protect the Karoopoort farm orchards from dust. The original old farmstead is on the right hand side of the road (west) when driving from east to west and looking its age these days. It is the only farm in the poort.
This poort primarily serves the local farming community to the south of Calvinia in the Northern Cape's Tankwa Karoo. It is a rough gravel road that runs on the North-West/South east axis through the Keiskie Mountains. The poort is named after the mountain range through which it traverses as well as the Keiskie farm, which lies 4 km to the south east of the poort. It connects the central sheep farming town of Calvinia with Middelpos - a minute hamlet of some 6 buildings including a post office and an hotel - 60 km to the South East.
Technically, this is not a poort, but a small mountain pass over a nek. It only takes four minutes to drive it, so do take the time to stop at the spacious view-site at the summit to enjoy the wide views over the mountains and plains. Here it is so still, you can hear your heart beating.
Whilst this is a basic farm road, it does provide a thoroughly enjoyable alternate gravel road drive to visitors to the Tankwa Karoo. The road can de driven as a circular loop of approximately 2 hours duration which will curve back towards the R355 and Calvinia to the North of the Bloukrans Pass. The pass rises 150 meters over 2.9 km producing an average gradient of a stiff l:15 with the steepest section being l:5.
It can be driven in any vehicle, but a high clearance vehicle is preferable. Be careful of the very sharp corner halfway up the pass
The Bloukrans Pass on the R355 some 20 km south of Calvinia, is one of four Bloukrans Passes in South Africa. It is named after the majestic Bloukransberge over which foothills the pass traverses. This is a safe, well designed road in all, but very wet conditions and snow does sometimes fall on the pass's upper reaches (1029m ASL)
The pass only has 15 bends, corners and curves, most of which are fairly gentle but the average gradient is 1:19, which is on the steep side. The road is wide and the gravel surface has good run-off, so even in rainy weather, this pass should present few issues to normal cars. However it is the approach sections on either side,which can get extremely muddy and slippery, so if its been raining heavily in the area, it is best avoided unless in a 4WD vehicle.
This minor pass is located some 35 km north-east of Calvinia in the Northern Cape. The name is interesting and a little misleading as this road does not conform to the definition of a poort and is much more of a classic 'down-up-down' profile type road over a nek. It's one of those roads not many people know about and is a perfect road to explore by car, 4x4 or bike. The road connects the farms to the north of Calvinia with Brandvlei as well as Calvinia itself. With an average gradient of 1:54 no-one will struggle to climb over this little pass. The road reaches its steepest point on the northern side of the summit where the gradient reaches 1:11.
We filmed this little pass very early in the morning in the late autumn of 2017. There is a remarkable sense of space, peace and solitude and the views of the mountains around the northern side of Calvinia are absolutely breathtaking. The road is generally in a reasonable condition, but as is the case with all gravel roads, this can change rapidly after rain, so drive below 80 kph and beware of corrugations. The shakiness in our video is evidence of the corrugations on this road (this despite deflated tyres and operatring in full 4WD).
Mountain Passes South Africa is a website dedicated to the research, documentation, photographing and filming of the mountain passes of South Africa.
Passes are classified according to provinces and feature a text description, Fact File including GPS data, a fully interactive dual-view map and a narrated YouTube video.
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.
