The Touw/Wilderness system is a unique and protected estuarine environment within the Garden Route National Park. This interconnected system comprises the Touw River estuary and the Wilderness Lakes—Island Lake, Langvlei, and Rondevlei. It offers superb light-tackle and fly fishing opportunities in a scenic, flat-water setting. The area is characterized by calm, shallow lakes, sand flats, channels, and extensive weed beds, creating diverse habitats for inshore saltwater species. Fishing here is governed by SANParks regulations, and the entire system is valued for its ecological significance as one of South Africa's few estuarine lakes.
