Ken, it really doesn't matter as the dunes you will cross are on made roads. Unlike the desert country where the prevailing winds form a steep side and a shallow side, the are all pretty even. Are you doing the Oodnadatta track both ways or going up the Stuart Hwy to Coober Pedy or Marla, back across to Oodnadatta and down the Track? There is a lovely campsite at Algebuckina on the Neale river about 70 kms south of Oodnadatta. Go through the gate on the eastern side of the road, south of the river crossing. Just and drive in a couple of hundred metres, you will find plenty of sites. Also the Hamburgers at the Pink road house are magnificent! Happy trails, Mike.

Mike thanks for taking the time to reply.At this stage we intend to cross from Coober Pedy to the Oodnadatta track and head down. Whether we go up to Oodnadatta and come back down is a question mark at this stage. I hate backtracking.Thanks for the camping and Hamburger tips. Ken
