The Ikara-Flinders Ranges National Park is situated approximately 400 km north of Adelaide in the northern central part of South Australia's largest mountain range, the Flinders Ranges. The park covers an area of 912 km², northeast of the small town of Hawker. The Heysen Trail and Mawson Trails pass through the park.
The park's most characteristic landmark is Wilpena Pound, a large, sickle-shaped, natural amphitheatre covering nearly 80 km², containing the range's highest peak, St Mary Peak. On 12 February 2016 the park was renamed to include the Adnyamathanha word, Ikara, "meeting place", referring to the traditional name for Wilpena Pound.
The park centre at Wilpena Pound is accessible by sealed road from Hawker. Other areas in the park can be reached by un-sealed roads, which are mostly accessible by two-wheel drive vehicles except in bad weather or after heavy rain. There are many lookouts, scenic vistas, small canyons and unusual rock formations located in the park. These include Wilpena Pound, Wilkawillina Gorge, Hucks Lookout, Brachina Gorge, Bunyeroo Gorge and Arkaroo Rock. The park has some stone ruins from early European settlement and Aboriginal rock art sites.
