Hi, we are a couple in our 60s, looking forward to our road trip from Melbourne to the Red Centre and back in October. We will be in our own 4 wheel drive & will be camping along the way & expect to be away 4 - 5 weeks. We hope to have 2 - 3 days at the Port Germein camping ground then on to visit Woomera, stopping overnight at the Glendamo Roadhouse. From there, 3 or 4 nights camping at Coober Pedy, (hope to go on the Mail Run tour). We also want to visit & take photos of the Painted Desert, before heading up to Alice Springs. My questions are, which camping ground in Coober Pedy would be most suitable for us in a tent? Will it cool down enough at night to get a decent sleep? Or should we spend up and stay at an underground b&b? We're not sure where best to camp for a night in order to visit the Painted Desert - Cadney Park or Arckaringa Station? From there, overnight at Kulgera or Erldunda Roadhouse ? ... before heading to Alice Springs. Any thoughts on our itinerary would be very much appreciated.
