In reply to grady_9:
We hired a little cottage at De Pakhus (the farm where Rocklands is situated) which had a shared pool with another holiday cottage - great to chill out after a day on the rocks. The owners are nice people and you are on a Roibos farm, which has now become my favourite tea.
As has been said there isn't much to do in the area other than climbing or walking, although a visit to the Mission settlement of Wuppertal is well worth it on an off day.
Stock up with food and booze in Clanwilliam.
I find that SAA or BA are the two best carriers to Cape Town. They are more expensive than some of the others which have been suggested, but the flight is direct, so there is no frigging around with meals and accommodation if you do a 1 or 2 stop flight which can wipe out what you save on a cheaper flight. Both have good on board entertainment, service and food.
If you are hiring a car at CT check the excess wording re accidents on unmade roads - you may NOT be covered. The road from Clanwilliam is unmade*. It's worth investigating insurance4carhire before you go for your excess because the compulsry excess in SA is very high and accidents on unmade roads common.
* It was on this road that I lost a hub cap which then overtook me! See previous thread on this subject.
