The Fitzroy River rises below Mount Vandyke in the Cobboboonee National Park, near the western edge of the Lower Glenelg National Park. The river flows east by south, through Heywood, then between the western edge of the Tyrendarra lava flow and the Mount Clay escarpment, and thence across a coastal plain. The river is joined by two minor tributaries before reaching its mouth and emptying into Portland Bay in the Great Australian Bight southeast of Tyrendarra. The river descends 138 metres over its 58-kilometre course.
