Flinders Chase is a national park on Kangaroo Island, South Australia, 213 km southwest of Adelaide. It is a sanctuary for endangered species and home to a few geological phenomena. Flinders Chase is composed of a group of protected areas at the western end of Kangaroo Island. It includes coastal landscapes, Cape du Couedic, Rocky River in the southwest, the Gosse Lands in the northeast and Cape Borda lightstation in the northwest. The park is located 110 km west of Kingscote, the island's largest town.
Since the creation of the national park in November 1919, Flinders Chase has become a sanctuary for endangered species, some of them introduced from the mainland in the 1920s and 1930s. During the 1940s, 23 additional species were introduced, including Koalas (1923) and Platypus (1928). Most of these species can still be observed today. Kangaroos, Goannas and Echidnas are commonly seen in the park. The park contains a few geological phenomena. Remarkable Rocks are naturally sculptured formations precariously balanced atop a granite outcrop. They remind visitors of the sculptures of Henry Moore. Admirals Arch, home to playful New Zealand Fur Seals, displays the ability of the ocean to carve the coastline.
