The Gellibrand River flows into the sea under the prominent headland of Point Ronald. The sandy beaches inside the mouth are often protected from the wind and in stark contrast to the turmoil of the ocean beaches. The estuary broadens into a wetland that is rich with birdlife and accessible via a boardwalk connecting the hilltop village of Princetown. Drive along the gravel Old Ocean Road to follow more of its meandering course upstream.
The Sherbrooke River is accessible via a walking trail in the Loch Ard precinct. The small river feeds into the sea near the battered low slung headland of Broken Head and the steep pitched Sherbrooke beach. The estuary view is dominated by the offshore Baker’s oven formation and the craggy Broken Head.
Campbell's Creek flows into the picturesque bay of Port Campbell. It's generally narrow mouth is often skipped over by enthusiastic visitors accessing the cliff cut steps to the Discovery walk. A favoured haunt of families offering shelter from the wind and much adventure for those with net and bucket!
The Curdies river inlet is a broad shallow expanse affecting the border between Port Campbell National Park and the spectacular Bay of Islands Coastal Park. Access to Peterborough from the east is via a bridge over the Curdies River. Wading birds abound in its upstream mudflats and the sandy outlet is favoured by families seeking respite from the ocean beaches.
