About Murphy's Haystacks
Murphy's Haystacks are ancient pink granite inselberg formations located on private farmland near Mortana, about 33 kilometres southeast of Streaky Bay on South Australia's Eyre Peninsula. Formed around 1,500 million years ago from Hiltaba granite, the weathered pillars rise abruptly from flat agricultural land. Named after traveller Dennis Murphy who mistook them for haystacks from a distance, they are a significant geological attraction and popular photography stop.
Visitors guide
Visitors can expect a field of large, weathered pink granite boulders and pillars scattered across flat farmland. The formations vary in size and shape, with some standing several metres high, creating a maze-like landscape to walk between and photograph. The site is in an open, exposed rural setting with unsealed access, information signage, and parking. There are no built structures beyond fencing and signage, with wide views of surrounding farmland and Eyre Peninsula countryside.
