The key draw to the farming town of Katherine (pop. 11,000) is Katherine (Nitmiluk) Gorge. It's small by the standards of, say, the Grand Canyon, but its dramatic sheer ochre walls dropping to a blue-green river make it an unexpected delight in the middle of the dry Arnhemland plateau that stretches to the horizon.
The gorge and its surrounding river ecosystem run through the 292,008-hectare (721,260-acre) Nitmiluk National Park. In the Dry, the gorge is a haven not just for cruisers but for canoeists, who must dodge the odd "friendly" freshwater crocodiles as they paddle between the walls. In the Wet, the gorge can become a torrent, and jet boating is sometimes the only way to tackle it. Hikers will find trails any time of year throughout the park. Farther afield are hot springs, water holes, uncrowded rivers to canoe, and Aboriginal communities where visitors can make dot paintings and find bush tucker.
