Howzit everybody.

I am looking for suggestions on what route to take to the Kgalagadi Transfrontier Park. I am familiar with the route from Cape Town but have recently moved to Pretoria and was wondering what the best route there is. I intend to drive the whole distance in one day and so I am looking for not only a quick route but also one with at least one fairly well stocked supermarket to do some grocery shopping.

The help is much appreciated.
