Recognised as one of the country's most evident geological sites, Glacial Hike takes you to significant points of interest such as the Sugarloaf and Amphitheatre which offer uniquely beautiful photo opportunities. The many interpretive signs along this three-kilometre loop trail describe the geological story of the area.
Resembling a mass of hard refined sugar, the Sugarloaf is shaped by rain and wind over a few thousand years. Its layers though were deposited when an ice cap melted during the so-called Permian time. The lower red layers are boulders and sediment while the brown cap is clay. The white is sand.
Similarly, the Amphitheatre is also produced by erosion. Its layers of sediments are from various periods of deposition. The top white band of soil limestone is calcrete while the bottom thin hard white layer is sandstone. In between are red purple mottled sediments and beneath are glacial sediments.
Glacial Hike is located within the Hallett Cove Conservation Park approximately 20 kilometres south of Adelaide. It features a combination of bitumen path, natural surface trail, track and boardwalk. So, do be mindful that some parts can get quite muddy after a downpour.
