In reply to UKC Articles:
A word of warning about car hire. Car hire companies in SA tend to impose a massive damage excess (sometimes 100%) for accidents occurring on gravel roads - see the photograph of the "typical Cederberg road". I would advise taking out a separate excess insurance in the UK before you go.
Try insurance4carhire . I've used them when intending to hire in SA, and did unfortunately have a, thankfully, relatively minor accident. I had to pay the excess which was the cost of the repair, but insurance4car hire honoured the policy and re-imbursed me on my return.
For an interesting sight seeing day off near Rocklands, Wuppertal, a village founded by German Missionaries is an interesting half day out.
