The western, Gulf St Vincent, coast of the peninsula consists of a continuous stretch of fine, white sand beaches. The eastern side is defined and separated from the mainland by the Barker Inlet and Port River. Torrens Island lies nearby to the east. To the east of the base of the peninsula is the suburb of Port Adelaide. Much of the peninsula has been developed, with residential areas extending inland from the western beaches, and heavy industries concentrated along the Port River waterfront on its eastern shore.
