The cultural and natural values of Kakadu National Park were recognized internationally when the Park was placed on the UNESCO World Heritage List. This is an international register of properties that are recognized as having outstanding cultural or natural values of international significance. Kakadu is the largest national park in Australia and is the second largest national park in the world. Kakadu is a biological wonderland, which is almost 8,000 square miles. The wildlife in Kakadu National Park includes over 280 kinds of birds, 60 kinds of native mammals, 55 kinds of freshwater fish, thousands of insects, and many reptiles(爬行動物), the most famous of which is the salt-water crocodile. All life in the park depends on water.

Kakadu is not only home to the wildlife but the area is also famous for the longest continuous human culture that exists in the world. Aborigines(土著) have been living in this area for at least 40,000 years. The descendants(后裔) of these First Australians still live in Kakadu today. Kakadu contains one of the longest continuous records of rock art in the world, with around 5,000 paintings, with rock sites dating back 25,000 years. More than 1,000 sites have been recorded. Kakadu has been given double World Heritage status by the United Nations. It is one of only 17 of the 469 World heritage Areas listed for both natural and cultural values.

It is Australia’s largest national park, but it isn’t just the size that surprises visitors — it is the sense of something very old and grand. Creation of the 500 km escarpment(懸崖) began 2,000 million years ago. Today those gorges are filled with rainforests, washed by waterfalls.

   Kakadu is one of the world’s special places. It is hard to pick the ideal time to visit Kakadu. In the wet season large areas of the park are closed to the public. It would not be possible to enter or exit from the park through the Kakadu Highway. Most of the people there agree that the best time to visit is at the end of the dry season. Some areas of Kakadu have restricted visiting times, and some are not open to the general public. Over 230 000 tourists visit Kakadu National Park every year. As you enter Kakadu National Park, you will be requir ed to buy a permit. Part of this money is paid to the Traditional Owners of the land and the rest is given to the repairs of the park.
