Murphys Haystacks, Granite rock formation in Mortana, South Australia, Australia

Murphy's Haystacks are a collection of pink granite rock formations scattered across the landscape of Eyre Peninsula, rising up to 10 meters high in places. These boulders were shaped over millions of years through natural erosion and weathering processes.

A traveller in a coach saw the formation from a distance and asked how a farmer could produce so much hay. The farm belonged to a man named Murphy, so the rocks became known as Murphy's Haystacks. The site is listed on the South Australian Heritage Register.

The name comes from a coach traveller who saw the outcrops from a distance and asked how a farmer could produce so much hay; the property belonged to a man named Murphy. The site is listed on the South Australian Heritage Register.

The formations stand in paddocks at Mortana, roughly midway between Streaky Bay and Port Kenny; the turn-off is from the Flinders Highway, not the Eyre Highway. Access is through private farmland, so visitors should use the marked track and leave gates as they find them. There is no shade among the granite pillars, so bring water and sun protection.
