Australia outback, sprawling, mostly uninhabited, and fabulously rugged, is one of the last frontiers of the modern age. The indigenous Aboriginal people have honored the ancient tradition of the walkabout as a signal of coming of age from youth to adulthood, spending up to a month on a solitary walk through this wild countryside.What better adventure than to take your own walkabout across the Australian outback. Because so few people inhabit the area, it is left to the graces of nature, unspoiled by modern expansion. There are beautiful flowers, exotic birds, and plentiful wildlife, a combination that draws thousands of tourists every year.
