This stunning park, covering almost 12,500 square miles (32,375 sq km) was added to UNESCO's list of World Heritage areas in 1984 and is regarded as one of the natural marvels of Australia. The land itself is believed to be more than two billion years old, and is a jigsaw of wetlands, gorges, waterfalls, floodplains, rainforest pockets and escarpments. It offers the visitor an impressive variety of superb landscapes teeming with wildlife, and features some of Australia's most magnificent examples of Aboriginal rock art. About 5,000 Aboriginal sites have been identified in the park area, making it arguably the best destination in Australia for those wanting to experience the oldest living culture on earth. The park can be visited on a day-trip from Darwin and contains more than 1,600 species of plants and 500 different kinds of birds and animals.
