May 12, 2026, Noarlunga Downs Wetland Trail

The Noarlunga Downs Wetland Trail is the perfect track for experiencing wetland habitats teeming with life. This flat dirt track is not very long and is surrounded with aquatic plants and grassland, where you will hear birds chirping, water of the river flowing and maybe even the faint sounds of the rail line passing in the distance. Enjoy this track during low tide and during a non-rainy day.

The Onkaparinga River flows through southern Adelaide and is popular with kayaking, fishing, and bushwalking on riverside tracks. The river valley has lush plants and marshlands here, and on the rest of its 88-kilometre course it flows through sandy shorelines and rocky canyons. It eventually terminates in Port Noarlunga.

A.S. Perry Reserve is a patchwork of marshland, native bushland, and open grassy areas along the banks of the Onkaparinga River. The reserve has restrooms, a playground, and picnic areas near its parking lot, but venture out on the bushwalking tracks to see the natural beauty of the area.

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.

This is where the Gorge hike comes to the Onkaparinga River. From Sundew lookout it’s a steep descent and often quite a rough path. From here, you can follow the river to the right or left.

Best accessible from Gate 11. It’s an easy walk here. If you dare, keep on going down to the Onkaparinga River via Gorge hike.

It’s a nice walk from the car park via the lookout. The last section down to the Onkaparinga river is quite steep but well worth it. To overseas visitors: the water looks dirty as everywhere here, but it’s safe to have a swim. So bring your swimmers!

Great spot for a swim, fairly challenging hike to get to it but worth it. Looking up at the cliffs from the pool is awesome.
