The Trezona Circuit is a Grade 3 (Moderate) hike located in the stunning Ikara-Flinders Ranges National Park, South Australia. Spanning 8.2 km, the trail takes roughly 4 hours to complete, offering a rewarding experience for hikers. As you walk, you'll encounter the park's rich wildlife, with kangaroos and emus frequently spotted along the way. The circuit also takes you through sections of the Heysen Trail, passing by the historic Camp Hut, a key landmark along the route.
The hike offers a chance to explore the Heysen Range’s open grassland country, providing expansive views of the surrounding landscape. Along the trail, you’ll also have the opportunity to discover the Trezona geological formation, which is home to some of the oldest life forms on Earth. Historically, this area was heavily grazed when the park was still a pastoral property, adding a layer of history to the natural beauty you’ll experience.
Flyers with info for interesting points along the hike are located at the trailhead, as well as at one of the checkpoints.

The total distance of a Grade 3 walk can be up to 20 kilometers.

Ancient and rugged mountain landscapes, peaceful tree-lined gorges, and a seasonal wealth of wildlife combine to make Ikara-Flinders Ranges National Park one of South Australia's iconic destinations. Covering approximately 95,000 hectares, the park includes the Heysen Range, Brachina and Bunyeroo Gorges, and the vast amphitheatre of mountains known as Wilpena Pound. Visitors can experience native wildlife, rich cultural heritage, impressive geological features, and a range of activities including bushwalking, four-wheel driving, birdwatching, photography, and mountain biking. Mild temperatures from April to October make this period the most comfortable for bushwalking and cycling, while summer temperatures can range from 30ºC to 45ºC.
Ikara-Flinders Ranges National Park has a rich and complex cultural heritage, combining Aboriginal and pastoral history. The park is co-managed by a board consisting of Adnyamathanha and Department for Environment and Water representatives. The Adnyamathanha people, meaning "hills or rock people," are the traditional custodians of the park, with a connection to the land that stretches back thousands of years. Visitors can view ancient rock paintings and engravings at Arkaroo Rock, Sacred Canyon, and Perawurtina Cultural Heritage Site.
Rugged mountain ranges, dramatic gorges, peaceful creeks lined with river red gums, and abundant wildlife are just the beginning of what awaits at one of South Australia's most popular tourist destinations.
