The Coral Lichen Circuit is a short, 1.1km loop trail within Aldinga Conservation Park, South Australia. Suitable for most walkers and taking around 45 minutes to complete, the trail offers a chance to discover the park's unique flora.
Beginning at the Dover Street carpark, the well-marked path winds through diverse vegetation zones. You'll encounter Tall Shrubland, stands of Mallee Box trees, and finally, the dominant Pink Gum eucalypts. A highlight of the circuit is a viewing platform overlooking a colony of the rare Lacy Coral Lichen, a spectacular Australian lichen species. From this platform, you can also enjoy scenic views eastward towards the Willunga Hills.
Starting at the Dover Street carpark, the initial section traverses Tall Shrubland with occasional Mallee Box trees. These soon give way to Pink Gums, the most common eucalypt in this area. The path continues towards a viewing platform, offering a glimpse of the rare Lacy Coral Lichen colony. Following the platform, the trail heads south, roughly parallel to the vegetated coastal dunes. Keep an eye out for markers that help identify prominent local plant species.
At Marker 11, turn east (left) and ascend to a lookout point built on the secondary dune ridge. This vantage point provides scenic views towards the Willunga Hills to the east. After enjoying the panorama, retrace your steps back to Marker 15 and turn north (right) to return to the carpark via the main north-south trail and the dune ridge.

Aldinga Conservation Park, established in January 2022, safeguards a diverse range of rare plants and animals. It incorporates the former Aldinga Scrub Conservation Park and the adjoining Aldinga Washpool, encompassing roughly 340 hectares of significant habitat.
The Willunga sub-basin landscape provides a dramatic backdrop for the park, featuring sand dunes, mobile dunes, and remnants of coastal vegetation. The Aldinga Washpool area is particularly noteworthy, containing a threatened coastal saltmarsh listed as a nationally vulnerable ecological community.
Lacy coral lichen, nardoo, hairy sedge, and several orchid species are just a few of the park's botanical treasures. Look out for short-beaked echidnas, lizards, bats, and the park's rich birdlife, which includes over 166 species. Spring brings a vibrant display of wildflowers, transforming the landscape into a colourful spectacle.
The Kaurna people have a deep connection to this land. They traditionally used the area during summer months, finding an abundance of food and materials for tools. Shellfish, fish, marsupials, reptiles, birds, and various plant foods were plentiful. Notably, the Aldinga Washpool held particular significance for the Kaurna people as a site for curing and drying possum skins. It remains a culturally significant location as part of the Tjilbruke Dreaming Trail and contains registered Aboriginal heritage sites.
