Clarence River Walls (Yamba/Iluka)

Moderate risk: Tidal current at river mouth

The Clarence River outflow creates strong tidal currents where the river meets the ocean, especially on an outgoing tide. Snorkel near the walls inside the river entrance in calm conditions.

Moderate risk: Boat traffic

The Clarence River entrance is a busy commercial and recreational boating channel with ferries, fishing boats, and vessels crossing the bar. Stay well clear of the main navigation channel.

Low risk: Ocean swell and shorebreak

When an easterly swell pushes in, the exposed sections of the breakwall can experience dumping waves and surging water. Snorkel on low-swell days only.

Low risk: Sharp rock/barnacle encrustation

The breakwall boulders are covered in sharp barnacles and oysters. Wear reef shoes or booties and avoid climbing on the rocks.
