South Australia comprises the dry hot north and the greener, more-temperate south. The green belt includes Adelaide and its surrounding hills and orchards, the Barossa Region and Clare Valley vineyards, the beautiful Fleurieu Peninsula, and the cliffs and lagoons of the mighty Murray, Australia's longest river. Offshore, residents of Kangaroo Island live at a delightfully old-fashioned pace, savoring their domestic nature haven.
The best way to experience this diverse state is by road. In general, driving conditions are excellent, although minor lanes are unpaved. It's two hours from Adelaide to the wine regions, the southern coast, and most other major sights. The most direct route to the Flinders Ranges is via the Princes Highway and Port Augusta, but a more-interesting route takes you through the Clare Valley vineyards. Two classic train journeys also wind through this state: the Ghan, which runs north via Alice Springs to Darwin, and the Indian Pacific, which crosses the Nullarbor Plain to reach Perth.
