The Williams River rises on the southern slopes of the Barrington Tops below Careys Peak within Barrington Tops National Park, and flows generally southeast and south, joined by ten tributaries including Chichester River, before reaching its confluence with the Hunter River at Raymond Terrace.

The river descends 749 metres (2,457 ft) over its 142 kilometres (88 mi) course;[4] through Dungog, Clarence Town and Seaham.

At Clarence Town, the Williams River is crossed by the Clarence Town bridge that carries Limeburners Creek Road;[5] and in Dungog, the river is crossed by the Cooreei Bridge that carries Stroud Hill Road.

[6] Both bridges are listed on the New South Wales State Heritage Register.
