The Robberg Peninsula is situated on the western side of Plettenberg Bay. In the 15th century Robberg was first named “Cabo talhado” (Sharp Cape) by the Portuguese and in around 1750 it was named Robberg (Seal Mountain) by the Dutch. Robberg has a unique rock formation where some of the oldest and youngest rocks in the world can be found in close proximity to each other. Robberg consists of 3 distinct layers known as the Robberg formation. Robberg is not only a unique geological site, but is also archaeological very interesting, with caves along the Peninsula that were inhabited for more than 19 thousand years.
