Watch out for the early morning mists. The baboons can also be a hazard. Otherwise this is a great ride for the speedsters and cruisers alike.
I have done this pass a few times, both ways, and it is very pleasant - except when the holiday makers are heading home and you have to deal with the caravans!
Scenic road over the mountains down to Mossel Bay. Lots of fast sweepers. A few tight corners.
