The effects of seas crashing mercilessly onto Australia's southern coast are visible in the oddly shaped rocks on the island's shores. A limestone promontory was carved from beneath at Cape du Couedic on the southwestern coast, producing what is known as Admiral's Arch. From the boardwalk you can see the New Zealand fur seals that have colonized the area around the rock formation. About 4 km (2½ miles) farther east are the aptly named Remarkable Rocks, huge, fantastically shaped boulders balanced precariously on the promontory of Kirkpatrick Point. This is a great place to watch the sun set or rise.
Much of Kangaroo Island has been cultivated since settlement, but after being declared a national treasure in 1919, a huge area of original vegetation has been protected in Flinders Chase. In December 2007 a bushfire burned a large part of Flinders Chase, and its destructive power and the various stages of regeneration are now on show.
Flinders Chase has several
1½-km to 9-km (1-mile to 5½-mile) loop walking trails, which take one to three hours to complete. The trails meander along the rivers to the coast, passing mallee scrub and sugar gum forests, and explore the rugged shoreline. The 4-km (2½-mile) Snake Lagoon Hike follows Rocky River over and through a series of broad rocky terraces to the remote sandy beach where it meets the sea. The sign warning of freak waves is not just for show.
The park is on the island's western end, bounded by the Playford and West End highways. The state-of-the-art visitor center, open daily 9–5, is the largest National Parks and Wildlife office. Displays and touch screens explore the park's history and the different habitats and wildlife in Flinders Chase. The center provides park entry tickets and camping permits, and books stays at the Heritage cabins. A shop sells souvenirs and provisions, and there is also a café.
