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
