Kangaroo Island is Australia's third-largest island after Tasmania and Melville Island. It is 112 kilometres southwest of Adelaide at the entrance of Gulf Saint Vincent. At its closest point to the mainland, it is 13 kilometres offshore from Cape Jervis, on the tip of the Fleurieu Peninsula.
Kangaroo Island is 150 km long and between 900 m and 57 km wide. Its coastline is 540 kilometres long. Kangaroo Island is one of South Australia's most popular tourist attractions, attracting over 140,000 visitors each year. Safe swimming is possible on the northern beaches, such as Emu Bay, Stokes Bay or Snelling Beach, and at Island Beach on the Dudley Peninsula. The island also has 28 wine growers.
A quarter of Kangaroo Island is conserved in National Parks, Conservation Parks, and five Wilderness Protection Areas.
