Wilpena Pound is an astonishing 800 million-year-old natural amphitheatre in the Flinders Ranges that, from above, looks like an upturned Frisbee. You come here for bush walks, fossil hunting – some of the oldest in the world have been found here – and mind-blowing sunsets. But if the Flinders isn’t remote enough for you, keep on driving. In another seven hours, you’ll hit Coober Pedy, a town built around an opal mine with desert cave hotels, cattle stations and huge skies. This is the outback of your imagination – Mad Max was filmed here, and it’s the dusty backdrop for the bright pink bus ride in The Adventures of Priscilla, Queen of the Desert.
At this point, you’ll be more than half way along the Explorers Way, an 1,800-mile route slicing through the outback from Adelaide to Darwin and vice versa. You could turn back, or you could press on into the Northern Territory, with Alice Springs another eight-hour drive away. Alternatively, head back to Adelaide and experience another gem of South Australia – Kangaroo Island.
