Gawler Ranges Track

Recently? No.
Drove it in a Mini in 1970. Was no problem then and Kingoonya was on the "highway".

Again, too fast, in a 4WD F350 motorhome in about 1995. I recall that the gravel got thrown about quite a bit that trip.

Can not imagine you having a problem provided it is dry.

In January I went into the Ranges via Kimba towing a 16' New Age Manta Ray Off Road Caravan. I was wet and slippery and as a consequence muddy, the day we drove in, but did not rain subsequently. We stayed in the Ranges for 3 days moving to a new camp site each evening, and exited via Yardea then across to Hiltaba and came back to the Eyre Highway at Pimbaacla. I had no problems other than the accumulation of mud on everything. Roads were well formed and not rough tracks at all.

The main roads in the Gawler ranges are continuously maintained by the government. Unless there’s been a recent very heavy rain event to damage them they are very passable. Sometimes will be a bit rough of course! They take a while to get over the whole lot.
Cheers and have a great trip in a great area.
