Onkaparinga River National Park protects a rugged section of the Onkaparinga Gorge about 30–35 kilometres south of Adelaide, where steep ridgelines, a narrow river valley, and permanent rock pools create one of the region’s most dramatic landscapes. The park includes a network of walking trails that lead to clifftop lookouts and down into the gorge, with abundant wildlife, including kangaroos, koalas, birdlife, and echidnas. The park also reflects a layer of history, with heritage-listed huts and 1880s ruins scattered among areas once used for farming.
