A biodiversity corridor is a land which connects two protected areas. Thus, a biodiversity corridor essentially attempts to reconnect the natural habitats which human interferences and activities had divided. This attempt is done so that the natural connectivity of nature is maintained and the extinction of species reverted. The Eden to Addo Biodiversity Corridor is one of the largest biodiversity corridors. It connects the Garden Route National Park, the Addo Elephant National Park, and the Baviaanskloof Mega Reserve. The corridor attempts to recreate the ancient paths used by the elephants for migration. The hike from Eden to Addo is the longest hike that is available in South Africa.
