[2] The English name "Jim Jim Falls" comes from the local Kundjeyhmi word andjimdjim, referring to the water pandanus (Pandanus aquaticus), a native plant.

The waterfall descends from an elevation of 259 metres (850 ft) above sea level via one drop that ranges in height between 140 and 200 metres (460 and 660 ft) into a plunge pool within the creek.

[5] The falls are located near the eastern boundary of the national park and 28 kilometres (17 mi) south of Jabiru.

In the dry season, access from the Kakadu Highway is possible via a 60-kilometre (37 mi) gravel road, with the final 11 kilometres (6.8 mi) suitable for four-wheel drive vehicles only.

Today the escarpment, which rises to 330 metres (1,080 ft) above the plains, extends over 500 kilometres (310 mi) along the eastern side of the national park and into Arnhem Land.
