After hearing lots about the Mariepskop's view, Young One and myself did a quick trip up the beautiful mountain in Limpopo. Actually it was my work's end year function and we stayed at Swadini Forever Resort just down the road, but we managed to sneak away while they spit braaied two sheep.
The D70 Road is just of the R531 - which splits of the R40 in turn. There is a nice little pub and small rural garage where the D70 starts. The first 26km is a sweet gravel road with a few sandy spots, but not hectic. I did not see many if any villages on the way up, so there are few locals around to hassle you. Just keep right on the main gravel road - there are a few left turn offs, but Google maps will clearly show you the way and it is easy enough.
Excuse the photo quality, I had to make due with my phone.
