Head to Desert Park, where the creatures of central Australia are all on display in one place, including many that are extremely difficult to find out on the trail. The predominantly open-air exhibits faithfully re-create the animals' natural environments in a series of habitats: inland river, sand country and woodland. It's an easy 2.5km cycle to the park. Pick up a free audio guide (available in various languages) or join one of the free ranger-led talks throughout the day.
Try to time your visit to coincide with the terrific birds of prey show, featuring free-flying Australian kestrels, kites and awesome wedge-tailed eagles. To catch some of the park's rare and elusive animals, such as the bilby, visit the excellent nocturnal house. If you like what you see, come back at night and spotlight endangered species on the guided nocturnal tour (bookings essential).
