Shhh - we like to keep some things secret!  If you know where to go, Adelaide has some beautiful beaches with white sand and clear water.  A beach walk at Port Noarlunga to the mouth of the Onkaparinga River is one of them.  Follow the white sand along the beach and breathe in the fresh sea air until the river mouth. Then, follow the river estuary back to the Port Noarlunga township.  Port Noarlunga is a 40 minute drive from Adelaide Holiday House.
