Separated from the Australian mainland about 9000 years ago, Kangaroo Island remains one of the most unspoilt natural wonders of the world. You'll find seals basking on quiet beaches; koalas munching on gum trees; echidnas wandering in search of insects; and kangaroos, goannas, wallabies, penguins and birds at just about every turn. One third of the island is protected as conservation and national parks, and half the island has never been cleared of native vegetation. You can walk among huge weather-sculptured granite boulders at Remarkable Rocks and roll down the white sand dunes of Little Sahara. Dodge the wildlife as you hike through bushland. Stretch out in your own secret spot along the island's 480 kilometres of coastline. And retire to your own lighthouse keeper's cottage for the night.
