Onkaparinga River National Park
A dramatic gorge just 35km south of Adelaide
A stunning river gorge and surrounding bushland just 35km south of Adelaide, with clifftop lookouts, riverside walks and rock pools teeming with wildlife.
An easy wilderness escape
Onkaparinga River National Park protects the dramatic gorge where the Onkaparinga River cuts through the Willunga escarpment before meeting the sea. Located just 35km south of Adelaide (before you reach McLaren Vale proper), it is one of the most accessible national parks in South Australia.
Walking highlights
- Punchbowl Lookout (2km): A short woodland trail to a spectacular lookout over the gorge
- Sundews Ridge Hike (4km, 2 hours): A moderate ridge walk from Sundews carpark
- Echidna Trail: Features heritage-listed 1880s huts and ruins
- Gorge Hike (6km, half day): A challenging descent into the gorge, along the river, and back up the ridge
- Chapel Hill Lookout Loop: An easier option near Old Noarlunga with views over the lower gorge
Wildlife
The park is home to kangaroos, koalas, possums, echidnas and over 100 bird species. The riverside rock pools support native fish, frogs and water birds.
Access
The main northern side walks are accessed from Piggott Range Road near Old Noarlunga. Free entry. No camping is available.
