a must to see in south africa are the funny guys in their black+white suits. you either can see and watch them at boulders entry directly, which is prepared for tourists, you pay an entry fee and walk along a wooden path which stretches to the beach. its good.
or you take the next road down to another parking area which is guarded as well and follow a tiny path hidden behind a gate with a sign saying "penguins hatching - quiet please" . here you follow along until you reach a beautiful empty beach (on the other side is the road with the golf course). you can swim freely with the penguins and that is really awesome!
