Escaping Adelaide for a day or two is easy and enjoyable. Close at hand are the Adelaide Hills, southeast of the city, which are popular for weekend outings and have numerous small national and conservation parks. To the south, the Fleurieu Peninsula extends towards Cape Jervis and has plenty of fine beaches and around fifty wineries at McLaren Vale.
If wine is your priority, head for McLaren Vale first, then the Barossa Valley, Australia’s premier wine-producing region, with another sixty or so excellent wineries within 50km of Adelaide. The valley is easily visited in a day from the city, but is also a great place to chill out for a few days. The Yorke Peninsula, across the gulf from Adelaide, is often ignored by foreigners, though many locals holiday here: as well as the wonderful beaches, it’s home to the remains of an old copper-mining industry and an excellent national park.
