Much of South Australia’s outback owes its existence to the old Ghan Railway, rattling along from Adelaide to Darwin. Your morning journey along the Oodnadatta Track reveals layers of history, rivalled only by the natural spectacle of Kati Thanda–Lake Eyre which you’ll glimpse along the way. Australia’s largest inland lake is typically a vast, shimmering saltpan, but occasional desert rains transform it into a vibrant oasis. You’ll witness its grandeur from above during a comprehensive scenic flight, where its abstract beauty unfolds like a living canvas. The flight also passes over the Anna Creek Painted Hills, a striking rocky outcrop bursting from the flat desert, its vivid colours forming surreal silhouettes. You’ll touch down to explore this otherworldly terrain before continuing to Coober Pedy, your base for the next two nights. Known for its underground homes and quirky charm, this opal-mining town promises a fascinating blend of adventure, eccentricity, and subterranean discovery.
