When on the N7 from the Cape side, don't take the Koringberg turnoff (The GPS will try to take you that way) - stay on the N7 until you reach the Velddrif R399 turnoff (left), or if you miss it you can ride on a few kilometers and take the De Hoek turnoff (Merges with the R399).

Just before you reach the mountains along the R399, turn left into the Moravia turnoff.
