Katherine sits about 244 km south-east of Darwin, and it is the hub for some of the Top End's best-known gorges, rivers and hot springs. Nitmiluk, or Katherine Gorge, is thirteen connected sandstone gorges carved by the Katherine River, with deep ceremonial meaning for the Jawoyn people, who manage the park with NT Parks.
Most of the campgrounds sit in town, near the gorge, or down the highway at Mataranka's springs. In Katherine, parks such as Knott's Crossing Resort are close to the river, and Nitmiluk is 23 km out of town. About 107 km south, Mataranka has Bitter Springs Cabins and Camping, with power and pets allowed, and north towards Darwin, Lazy Lizard Caravan Park is in the old gold town of Pine Creek.
At Nitmiluk, you can paddle the gorge by canoe or take a flat-bottomed boat up to the fifth gorge in the dry season, and look out for red-tailed cockatoos and Gouldian finches. In Katherine, the Katherine Museum is close to the Katherine South parks. At Mataranka, the thermal spring sits in Elsey National Park, with a reconstructed homestead nearby from Jeannie Gunn's 1908 book We of the Never Never. In Pine Creek, the railway station is part of the heritage precinct, and further south, the Larrimah Museum is right by the caravan park.
The Jatbula Trail follows a historic Jawoyn walking route out of Nitmiluk. Mataranka Hot Springs is a natural thermal spring, and south-west of Katherine, the Douglas Daly area has Butterfly Gorge and Douglas Hot Springs. The Daly River is known for barramundi fishing.
The dry season, from April to October, is when most gorges and rivers open for swimming and boating. The wet season, roughly October to April, brings monsoon rain and can cut roads with flooding.
Only in designated swimming areas. The Katherine River's freshwater crocodiles are considered harmless, but saltwater crocodiles can move in during wet-season floods, and the Daly River Nature Park is home to saltwater crocodiles. Swim only where the NT Government lists a designated swimming area, and never where crocodiles may live, even without a sign.
Yes. 3 campgrounds here have powered sites confirmed: Bitter Springs Cabins and Camping, Lee and Jenny's Bush Camp and Boab Caravan Park. For the rest we are still confirming, so check with the park or holiday park before you book a powered site.
