Along the Wildside there are many fresh water springs that originate from water that has collected between the (vegetated) sand dunes along what used to be the Driftsands area. The water then emerges again on the coast in the form of springs and flow to the sea. In some places it dams up above the high water mark between rocks and swampy spots get formed. In the search of a geocache the other day I had to cross through one of these close to Schoenmakerskop and boy did I have to walk carefully to avoid getting my shoes wet. You won't encounter any crocs or even the Swamp Thing in these any time soon though.
