Aldinga Beach

Aldinga Beach is a long sandy beach in the suburb of Aldinga Beach within the City of Onkaparinga, about 45 kilometres south of Adelaide, South Australia. It is known for its wide white sand, clear waters and the offshore Aldinga Reef Aquatic Reserve. The beach allows vehicle access in a designated section and is popular for swimming, snorkeling, surfing and fishing, backed by coastal dunes and the Aldinga Washpool wetlands.

Visitors can expect a wide, white sandy beach stretching for several kilometres with clear shallow water, low dunes and views across Gulf St Vincent. The beach is backed by the Aldinga Scrub and Washpool lagoon. Offshore lies the Aldinga Reef Aquatic Reserve with intertidal reef visible at low tide. There are designated vehicle-access sections, swimming and snorkeling areas, a snorkel trail, walking paths along the coast, and open space for picnics and beach walks.

The Aldinga area is part of Kaurna Country. European settlement began in the 1840s-1850s with the township of Aldinga established in 1851 as a farming and coastal settlement. The beach and reef have long been used for fishing and recreation, with the Aldinga Reef Aquatic Reserve proclaimed in 1971 to protect the reef ecosystem.
