Port Noarlunga Reef

Snorkelling in Gulf St Vincent

Wander along Port Noarlunga's lovely old timber jetty to explore the reef – actually a remnant of an ancient dune, now a 1.6km-long shoal that's home to 50-plus fish species and hundreds of types of marine plants. Strap on a snorkel: a trail of a dozen underwater plaques tells you what you can see under the sea.
