The Knysna Lagoon opens between two sandstone cliffs known as the Heads – once proclaimed by the British Royal Navy to be the most dangerous harbour entrance in the world. There are good views from the eastern head, and from the Featherbed Nature Reserve on the western head.
The best way to appreciate the lagoon is by boat; the Featherbed Company operates various vessels.
Although regulated by SANParks, Knysna Lagoon is not a national park or wilderness area. Much of it is still privately owned, and the lagoon is used by industry and for recreation. The protected area starts just to the east of Buffalo Bay and follows the coastline to the mouth of the Noetzie River.
