IMPORTANT NOTICE: The old farm over which this road traverses has been sold to a new owner, who has subsequently locked the gates at either end, so this pass is unfortunately no longer publicly accessible.
This gem of a pass is a well hidden secret, which lies in an isolated valley to the north of the Klipbokkrans and Baviaansberg mountains [1946m] and follows the natural kloof formed to the south of the Grasberg mountain [1638m]. It lies on the east/west axis and at 16,1 km is quite a long pass. It's not only long in terms of distance, but in time too. You will need at least 1,5 hours to complete the kloof itself and that excludes the southern return leg over many kilometres of farm roads.
Multiple farm gates and to a fairly dodgy road, which can be in various states of disrepair, all add to the remote and rugged allure. It's best done in a 4x4 or at least a "bakkie" with good ground clearance and diff-lock. Despite the average gradient being an easy 1:30, there are some very steep parts, especially near the summit, which reach 1:6. During winter and after rain, there are multiple river crossings to negotiate, none of which are crossed over any bridges. The rewards however, are magnificent.
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.
Ceres has an abundance of passes connecting it with the outside world. One of the biggest is the Theronsberg Pass which forms a trio of passes into the north with the Hottentotskloof Pass and the Karoopoort. The pass (on the R46) connects Ceres with the R355 to Calvinia and Sutherland as well as linking up with the N1 highway just north of the Hexrivier Pass via another pass on the R46 - Die Venster (The Window).
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.
