This tar road pass is located near Prieska in the Northern Cape, and follows a loop in the Orange River known locally as “Wonderdraai” (which translates as “amazing corner”). This horseshoe-shaped bend, together with its surroundings, creates an optical illusion that the river is flowing uphill. The pass itself gains just 77 metres in height and has a total of 9 corners, only one of which exceeds an angle of 90 degrees. The road is in a fairly good condition, with just a few minor potholes, and can be driven in any vehicle and in all weather conditions.

The pass is situated only about 22 km from the town on a good tarred road, so it is worth making a slight detour to get to if you are in the area. Speak to one of the locals and ask about the location of the best viewpoint for the Wonderdraai phenomenon.
