Knysna Coral Lake is the estuary of the Ness River in Cape Town. It is a large lagoon formed by changes in the siltation terrain. The entire lake is about five kilometers in size and the water is clear. Because the lakeside is full of reed swamps and the natural environment is good, it has become a paradise for migratory birds to reproduce. In the green mountains and clear waters, the Coral Lake is like a dazzling pearl that is intoxicating.
