The Iluka side (south of the breakwall) and the Yamba side both provide shore-entry snorkelling around the rock habitat, with the river current adding a dynamic edge. The Iluka breakwall separates Andersons Beach from Iluka Beach, while the nearby Bluff Beach sweeps north to Frazers Reef — a secluded snorkel spot.
