Trail summary
Hike overview
The Mawson Spriggina Walk is an 8-kilometre loop trail within Arkaroola Wilderness Sanctuary, South Australia. Considered the easiest of the three main hikes offered, it takes approximately four hours to complete. This scenic route traverses the Mawson Valley before ascending Spriggina Ridge, rewarding walkers with panoramic views of the surrounding landscape.
Beginning near the village, the trail follows a gentle incline along the foothills, eventually reaching The Pinnacles. These fascinating rock formations, estimated to be 450 million years old, are composed of exposed granite. The path then winds between The Pinnacles, offering captivating views from various angles.
Continuing from the car park, the trail delves into natural bushland before climbing a slight rise to reach the Spriggina Lookout. The namesake "Spriggina" refers to a fossilized flatworm that thrived here millions of years ago when the area was an inland sea. A large replica Spriggina positioned near the lookout provides visitors with a visual representation of this ancient creature.
The descent from the lookout offers views of the Arkaroola Observatory in the distance. Upon reaching the camping area, a short circuit around the village completes the loop and brings you back to your starting point.

About the region
The Arkaroola Wilderness Sanctuary, in South Australia's remote northeast, is a haven for geology enthusiasts. Established by the Sprigg family, the sanctuary honours the legacy of the late Reg Sprigg, a distinguished South Australian geologist. His work included significant geological discoveries in the northern Flinders Ranges and Cooper Basin, and he played a key role in founding Santos and Beach Petroleum.
Arkaroola boasts a remarkable geological tapestry. Rugged mountains, towering granite peaks, and magnificent gorges characterise this ancient landscape. Mysterious waterholes dot the terrain, providing habitat for a diverse range of Australian wildlife. Birdwatchers will be delighted by the variety of avian species, while reptile and mammal enthusiasts can search for creatures including the shy and endangered Yellow-footed Rock-wallaby. Notably, Arkaroola is considered one of the best places in Australia to observe these rare marsupials in their natural environment.
Visitors can explore this extraordinary landscape on foot, following in the footsteps of early explorers. The sanctuary offers a network of well-marked walking trails suitable for most ages and abilities. The latter section of Griselda Hill presents the most challenging terrain. Brochures detailing the trails are available for purchase at the Arkaroola Resort Village.
