From the N1, take the Allandale turnoff at Midrand and head towards Kempton
Park (East). At the top of the hill at the traffic lights, about
400-500 meters turn right (North), then turn left about 300 meters down the
road. It's next to the quarry. Once on the dirt road to the quarry, a few
hundred meters, you will get a split in the road, right to the quarry, left
to NERF.
