The Kimberley is a remote region of Western Australia bordered by the Indian Ocean and the Timor Sea. Closer to Jakarta than to Sydney, this rugged 135,600-square-mile area is home to just 40,000 people. Cattle stations take up some of that space, but for the most part, the landscape comprises craggy sienna-hued ranges, limestone and sandstone gorges, emerald forests and wetlands, and forbidding cliffs that plunge into the ocean. A large number of protected nature reserves and national parks attract hikers and bird-watchers to the region. The Purnululu National Park, designated a UNESCO World Heritage site in 2003, is composed of semi-arid savanna grasslands and a range of sculpted sandstone rocks called the Bungle Bungles.
