I love mountain passes and actively seek them out. The one in the video does not have a name to the best of my knowledge. It is very short and possibly cannot even be considered a pass, but I believe it is the steepest I have driven. It outdoes the Botterkloof pass in Namaqualand.
Where is it? It crosses the Gouritz River about 50 km east of Herbertsdale. If you want to find it on Google Maps search for Willie se uitkykpunt.
Apologies for some bad images, but I was using a hand held camera balanced on the steering wheel and my wife was not with me so I had to do it all myself.
