Certainly the Cape - but I can't see Chapman's Peak in it. I used to drive it often, and know it well.
In the 80's, before Chapman's Peak was closed from rock falls (and then became a toll road) we used it often for vintage car rallies. Great memories.
It could well be on the road from Gordon's Bay to Hermanus via Rooi Els (the coastal Route). Just as beautiful, but not as dramatic.
