Adelaide, the laid-back capital of South Australia, is a world away from the urban powerhouses of Melbourne and Sydney. The only one of Australia’s state capitals to be founded by free settlers, Adelaide retains its independent spirit to this day, and it feels more like an oversized village than the country’s fifth most populated city. With its Victorian architecture, picturesque waterfront, burgeoning art scene, and myriad other things to do, Adelaide is a city-break destination in its own right—but for many travelers it's also home base for day trips to the vineyards of the Barossa Valley and McLaren Vale, Murray River, Kangaroo Island, and Fleurieu Peninsula.
