The Ringarooma River rises below Mount Maurice and flows generally east by north, joined by ten tributaries including the Maurice River (Tasmania), Dorset, Cascade, Weld, and Wyniford rivers.

In the lower reaches of the river, the topography comprises a floodplain and forms part of the Ramsar Lower Ringarooma River wetland.

[2] The river reaches its mouth and empties into the Tasman Sea at the Ringarooma Bay.

The river descends 1,020 metres (3,350 ft) over its 124-kilometre (77 mi) course.

[1] The Tasman Highway crosses the river on multiple occasions as part of its course.
