All right. First time I noticed this thread...

Will add my two cents for whatever South African drivers are here on the forum to try.
1. Chapmans Peak. Beautiful Scenery, lovely sound and of course the chance of possible rock falls which means you have an excuse to drive as fast as possible.

2. Black Hill in Simons Town. Road surface is a bit bumper but the road is always quiet and the corners are superb.
3. Sir Lowries Pass. Nice uphill going into some hectic turns. Dont get too confident.... You may find spill diesal (This is common) on the final corner.... Drifting is possible. I have personal experiance of this.
4. Theewaterskloof Dam Pass. Once again. Scenery is incriedible and the road is fun. Beware of corners that randomly become sharper in the middle of the corner. You have to be a good driver for this mountain Pass.
5. Grabouw. Close to the Theewaterskloof Dam Pass but more fun and less tricky.
There we are. My favourite out of all of them? Chapmans Peak. Its just too much fun
