Little is known of the early history of the area surrounding the Groot and Sout estuaries. The densely forested terrain dissected by deep gorges caused the area to be avoided by early travellers who used the inland route via the Langkloof to Algoa Bay. The Groot estuary, bordering on South Africa's only coastal National Park, is in an almost completely natural condition. The Sout estuary is a predominantly tidally driven system consisting of narrow upper reaches opening into a relatively broad sandy cove which in turn opens to the sea through rocky promontories.
