The Seven Mile Road lookout at Noonameena provides views across the Coorong (lagoon) to the sand dunes of the Younghusband Peninsula. The Coorong at this point is 2km across and the walking distance through the sand dunes from the opposite shore to the ocean beach is 1km. The water varies from very shallow to more than head height and the surface below varies from solid sand to soft mud and rough rock. Despite it’s apparent shallow appearance you will need water-craft to make this crossing. The lagoon continues north to the Murray Mouth and south to 42 Mile Crossing. In all this saline lagoon is over 100kms long and Noonameena is sightly north of central along this stretch. It is fed from the north my the Murray River and from Salt Creek in the south from the South-East Drainage Scheme. The change in water level is driven primarily by the wind. In warmer months the water is driven north and out through the Murray Mouth. In cooler months the lagoon fills as water is driven south.

Coorong National park was declared in 1966, to conserve the distinctive landscape, the coastal dune system, the lagoons, wetlands and coastal vegetation and the great variety of birds, animals and fish that live in or visit the area. The Coorong is an archeological site of international significance with middens and burial sites throughout the Park giving evidence of Aboriginal occupation over many thousands of years.
