The area is access sensitive!
The field you park your car to is an actual Rooibos field!
It means, that do not tramp on the field, do not drive through the field or anything else as stupid as that.
Do as the trail here suggests. You walk alongside the field (parallel to the asphalt road) for 500 meters, turn 90 degrees left and walk for 450 meters and you should find some cairns leading you to the Nachorizma.
