A long walk along an empty beach on Yorke Peninsula will eradicate those mental cobwebs. In the rural hinterland, fields of ripening grains glisten like Vincent van Gogh landscapes. The peninsula's boot-like shape juts out between Spencer Gulf and Gulf St Vincent and calm, shallow waters and sheltered coves make for carefree family beach holidays, especially the safe swimming to be had at charming Marion Bay.
The Copper Coast towns Moonta, Wallaroo and Kadina, owe their distinct character to the Cornish 'Cousin Jacks' who, in the 19th century, came to work the mines. Walk through the Moonta Mines State Heritage area and drop in to the Moonta Mines Model School, built 1875, now a museum.
At the foot of the peninsula - the toe, literally - lies Innes National Park, 9,200 ha rugged hectares of mallee woodland, coastal heath and stable dunes.
