Don't bother with Pearly beach. Go straight to Die Dam. Follow the road that leads towards the beach park just before the dune and walk onto the beach. You can fish off to the left and to the right.
About a kilometer towards the left is a spot where the beach and some rocks meet....good spot. As well as further along is a spot called Rietfontein. Also very good. Cob and steamers. Fish with the usual; chokka and sard. Dingle dangle presents best results.
