The wild heart of Tasmania This boardwalk leads to one of the many lakes that dot Tasmania’s Cradle Mountain-Lake St. Clair National Park, one of the crown jewels of the island’s Wilderness World Heritage area. Covering over 623 square miles (1613 sq km) in the interior of the island, the park is home to an incredible diversity of flora and fauna. Marsupials like Bennett’s wallabies, quolls, Tasmanian pademelon, and the legendary Tasmanian devils, as well as short-beaked echidnas, platypuses, wombats, and Tasmanian pygmy possums, can be found in its ancient forests and lakes. #Picture
