Jim Jim Creek flows through the central portion of Kakadu National Park in the Northern Territory, eventually draining into the South Alligator River system via Yellow Water billabong. The creek passes through dramatic sandstone gorge country, and the section near Twin Falls is notable for its rugged scenery and wildlife, including freshwater crocodiles and the rare pig-nose turtle.

Access to the Jim Jim Creek area is restricted to the dry season, generally May through September. The road to the area requires a high-clearance 4WD vehicle, and the creek vehicle crossing — which has a concrete base — typically runs 400 to 600 millimetres deep, occasionally reaching 800 millimetres. Conditions should be confirmed with the Bowali Visitor Centre before visiting, as road closures are possible.

A commercially operated boat shuttle runs on the creek near the Twin Falls car park, departing every 15 minutes between 7:30am and 4:30pm. This shuttle, operated by local Aboriginal guides, is the established means of traversing the gorge section toward Twin Falls. Fishing is permitted on Jim Jim Billabong within the Jim Jim Creek system, though specific regulations apply within Kakadu National Park. The Garnamarr Campground, located approximately 5 kilometres from the falls car park, provides facilities including showers, toilets, and barbecues during the dry season.
