Coober Pedy, a quirky town in northern South Australia, is known as the "opal capital of the world" due to its abundance of precious opals. The town's unique charm lies in its underground dwellings, called "dugouts," which provide relief from the scorching desert heat. With a mix of opal mining history, underground attractions, and a laid-back vibe, Coober Pedy has become a popular stopover for tourists seeking a one-of-a-kind outback experience.
