Agreed. Outeniqua Pass is also stunning in a different way.
Make a stop at the "4 Passes" view point....quite far from the top....3rd one from the top to be precise. So named because you're on the one pass....you look down on Montague Pass, you look across at the railway line, and the old Cradock Pass ( if you know what to look for) which was the original crossing over those mountains, done with ox wagons. If you stand and look at it and contemplate that thought, it's mind blowing.
The said pizza joint is Roadside Deli....ja, everyone here raves about their pizza's...I've not tried it yet.
