Excuse the poor quality of this image - which is a photo of an old, framed photo - but this is the best way to demonstrate the challenging nature of the 'main' access road to Wuppertal!
The 'main road' links northwards to the good tar road from Clanwilliam - of which the final section is the impressive Pakhuis Pass - and is about 40km of dirt (unsealed or gravel) road. I don't have a problem with dirt roads per se - I do a fair amount of driving on gravel, and in rural areas, a well maintained dirt road can be infinitely preferable to a badly maintained tar road - but I have to confess that I took a bit of strain on this one!
The problem with this road is not so much a matter of poor design or maintenance, but simply that the same elements that make the road gorgeously scenic - the harsh terrain and precipituous slopes - does not lend themselves to user friendly road design. The gradients are severe, and matters were not helped by the fact that our hire car was a hopeless automatic Chevrolet with about as much torque and grunt as an asthmatic tortoise!
In an effort to improve road conditions, certain of the steepest sections have been surfaced with concrete, which does help to stabilise the surface. The excellent "Cedarberg to the Sea Explorer" publication tactfully describes the road as, "suitable for ordinary cars, but challenging after heavy rains". The road is fine under dry conditions if you take it slowly and aren't of a nervous driverly disposition, but I would certainly think twice about driving this road in a two wheel drive vehicle during or after bad weather.
Definitely better suited to donkey carts!
Wuppertal is the sort of place where motor vehicles feel incongruous at the best of times, so it should come as no great surprise that livestock have right of way!
