It’s a bit of a trip from Adelaide’s centre, but the boat ride to Kangaroo Island is one of the few “Absolutely Must Dos” in this laid-back corner of Australia. It’s Australia’s third largest island, and home to blue seas, white cliffs, black caves and green hills. More than a third of the island is protected as national parks and game preserves, and inside or outside you’ll have an eyeful of birds and smaller critters wherever you look.
In the “It’s exactly what it sounds like” department, the island is home to a ridiculous number of roos, plus seals, sea lions, koalas and dolphins. Lodgings are plentiful (and reasonably priced, considering) so come for a night or two nights to make the most of your visit.
