We'll soon be driving through Phalaborwa, on the way to Olifants camp. We've read that there's a 'fantastic' viewpoint for Phalaborwa's huge Big Hole open-cast mine, which sounds like an - er - interesting contrast to all the wildlife. But where is that viewpoint? I can clearly see the mine on the Google Maps satellite-view, but we probably won't have time to drive round and round looking for the actual viewpoint. If anyone here can point us in the right direction, that would be great (we'll be coming in from the south on the R40). Alternatively, feel free to steer us away if the viewpoint's a big anti-climax (or if it's in an area where strangers might not feel totally confident driving about on their own...).
