Found a nice road that runs through the mountains between Stormsvlei and Drew. It's nice and scenic and cuts out a huge chunk of the N2.
I rode to Drew, then turned right just after the bridge (towards Hessequa 4x4). About 5 km down the road was a turnoff that said Kliprivier (I think). I could see the road going over the koppies and there were recent DS bike tracks (2) heading up that way. After a while I came to a fork - one looked like it went to a farm house so I took the other one even though it was obviously less travelled. As you can see from the pics a car would never get through after the recent rains.
Then I ran into some guys on tractors and I asked them if the road goes to the "groot pad" and they said yes. It's obviously a farm you ride through and before to long I ran into the farmer dragging a planter behind his Land Cruiser bakkie. Friendly guy, said "Yes, go and enjoy" when I asked permission
The road ends at a to your right just as you come out of the pass between Stormsvlei and Bonnievale. Here's some pics:
