Margaret River Mouth Beach (WA 660) lies across the mouth of the usually blocked river. The beach faces southwest and curves for 500 m between boundary calcarenite bluffs of the old valley side to the south and a low reef to the north, where it forms a sandy foreland. It is backed by the dammed river which can break out and either end of the beach, resulting in a flat overwashed area behind the steep beach.
The beach is partly protected by reefs, with waves increasing in height up the beach to about 1 m. Lower waves break right on the steep beach, with higher waves breaking as a heavy shorebreak or heavily on a narrow bar. The short heavy beach break, known as Margaret River Mouth, while a hazard to swimmers does attract surfers when waves exceed 1 m.
The Margaret River Surf Life Saving Club was provisionally established at this beach in 2003 and patrols the beach on Sundays during the summer period.
