Korowan (Mataranka Falls) sits along the Roper River within Elsey National Park in the Northern Territory.

The falls are reached via a moderate 8-kilometre return walk of roughly four hours, following the river downstream through one of Australia's largest stands of Livistona rigida palms.

The falls owe their character to a series of tufa dams — natural formations created when lime-rich spring water gradually deposits mineral build-up on rocks and vegetation, eventually building a lip or dam across the river.

Over time these structures redirect the flow, producing gentle rapids and waterfalls. The site also offers fishing access along the riverbank. Saltwater crocodiles inhabit the Roper River, and visitors are advised to follow current Crocwise guidelines.
