Messelpad/Wildeperdehoek Passes (Namaqualand)

It took three years for our first reader submission video to be processed. Johan Buys from Durbanville sent in footage from a recent trip through the Namaqualand National Park which routed over these two historic back to back passes. We thought he did a terrific job. The videos are now live on the website. This must be a great route on a bike?

I am not sure if bikes are allowed in the National park? Can someone verify this point please?
