We will be visiting Flinders Ranges in October. We are driving up from Adelaide along the scenic route, via Clare Valley, On the way back we will be stopping overnight in Barossa Valley, before catching a flight to Melbourne. We would like to take a scenic - not necessarily the quickest - route from Flinders to Barossa. Our current thinking is to take B80 / A32 via Peterborough.
Does this sound like a good plan? How much time should we allow for this drive?
