Two thirds of South Australia is almost empty, occupied by just one percent of the population. There are four deserts: the Simpson, the Great Victorian, the Sturt Stony and the Strzelecki. Although the Nullarbor Plain is featureless of thousands of kilometres there are some walks of note:

Heysen Trail is the longest constructed walking track in the country (with the exception of the Bicentennial National Trail). It runs for 1500km from the Flinders Ranges, Wilpena Pound, Aroona Valley, the Barossa Valley, Mt Lofty Ranges and down the Fleurieu Peninsula via the wine region of McLaren Vale, all the way to the Kangaroo Island Ferry at Cape Jervis.

The Trail was named after Sir Hans Heysen who made frequent trips to the Flinders and whose house can be visited at Hahndorf in the Adelaide Hills where his daughter still paints.

Kangaroo Island (K.I.) is the third largest island off the coast of Australia – 155km long and 55km wide. It really is a must see and a must walk:
Cape Gantheaume Wilderness Trail Walk on the south eastern side of K.I. is 34km long and will take a couple days. Flinders Chase National Park at the other end has lots of short walks – Admirals Arch (home to Australian and New Zealand Fur Seals &, Remarkable Rocks (location for some scenes from the movie “December Boys” starring Daniel Radcliffe aka Harry Potter). One of the most stunning walks you can do is amongst the Sea Lions at Seal Bay – A MUST DO!
