Found some pictures on the Internet re. the sardine run.
The little fish that causes all the excitement.
A shoal of sardines photographed from underneath.
Map showing the location of the Sardine run. After the shoals pass Durban, they turn seaward and disappear. Some people say that they make a circular journey returning to where they came from.
If you look at the map where the Drakensberg turns north west, a little to the north and east of that on the highway shown, is where you would find Estcourt.
