The Karretjies Pass is a rough, narrow track that descends down a side arm of the Bobbejaanskloof, itself a side canyon to the much bigger Doring River canyon. Although this pass is short at just 1,5 km and has an altitude variance of only 72m, it is the rough nature of the road that makes it something of a challenge. It offers majestic canyon views, steep drop-offs and a feeling of intense isolation in a harsh and barren landscape.
The road has been hacked out of the side of the mountain and is only just wide enough for one vehicle. Overtaking or passing is impossible. You will need a high clearance 4x4 to drive this pass and low range will be an advantage for more precise control. The pass forms part of the Old Postal Route that connects the Biedouw valley in the west with the Eilandsvlei farm near the R355 in the east in the Tankwa Karoo. Do not attempt this pass without reviewing our page on the Old Postal Route first, which contains very important information on navigation and safety.
The Old Postal Route is a basic gravel track of 53,2 km that connects the Biedouw Valley in the Cederberg with the Eilandsvlei farm near the R355 in the Tankwa Karoo. This was once a route used to deliver post between these two remote communities.
The route consists of two mountain passes separated by a long high altitude plateau and includes a bridgeless crossing of the Doring River at the eastern end. It is not suitable for normal cars. Four wheel drive with high clearance is essential and low range is an additional benefit to have at your disposal.
Most of the route is Grade 1 and fairly straight-forward to drive, but here and there a few tricky sections raise the bar to Grade 3, depending on weather conditions. The two most likely places drivers will have problems, is the crossing of the Doring River and offroad navigation, as there are multiple unsigned intersections, so your navigation needs to be precise. Unless you have a GPS loaded with Tracks4Africa where you can see the route clearly, you will more than likely get lost. We don't recommend driving this route between June and October, when water levels in the Doring River will probably be too high. In summer, the river crossing is usually bone dry.
The route will take between 4 to 6 hours to complete, depending on a number of factors. There are cottages and camping available at Mertenshof near the western start and good camping can be enjoyed at Die Mond off the R355 at the opposite end of the route.
The route is best driven in a group in case of a breakdown. Take full recovery gear with as well as a puncture repair kit that you know how to use. If you enjoy remote gravel road driving, with huge vistas and a unique stillness you will find in few other places in South Africa, then this route is for you.

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.
