Hallett Cove Conservation Park

Hallett Cove Conservation Park is a protected area in the Australian state of South Australia located in the suburb of Hallett Cove on the coast of Gulf St Vincent about 22 kilometres (14 miles) south of the centre of the state capital of Adelaide.

Hallett Cove is one of the best known geological sites in Australia and is known for its international significance. The area has been declared a Geological Monument by the Geological Society of Australia and placed on the South Australian Heritage Register for its educational and scientific significance. It is also a site of great archaeological significance, with evidence of some of the earliest Aboriginal settlement documented in Australia, dated at 40,000 years ago. Some of the features in the park are Waterfall Creek, Black Cliff and the Amphitheatre. A freshwater spring near Waterfall Creek is one of the features of the Tjilbruke Dreaming Track. As of 2021 the park is included in the Glenthorne Precinct of protected areas.
