Made famous by ‘Crocodile Dundee’, Kakadu National Park is one of the best places to visit to see Australia’s varied wildlife. Some of the park's most famous inhabitants are the crocodiles and water buffalo, though kangaroos, wallabies, possums, bats, kookaburras, goannas and other visitors' favourites are all here if you know where to look for them. There are also exotic birds and large and varied populations of fish, reptiles and insects. Located at the top end of Australia, nearest to the equator, the park supports a range of ecosystems, from the wetlands favoured by buffalos and waterfowl, to the low lying scrub and tall grasses where kangaroos live and the rocky bush land of the escarpment. The six- to ten-foot castle-like termite mounds are the park's most interesting insect feature, created by huge termite colonies out of dried grasses. The hot days mean that most animals, including the crocodiles, are most active in the evenings and at night. This is also a place of great traditional significance to the aboriginal population, and paintings on the walls of many of the park's caves tell the stories of the people who have been living in this area for thousands of years.
