In Onkaparinga River Recreation Park, the river spills onto the plains, creating wetland ponds and flood plains. The area conserves important fish breeding habitat and hundreds of native plant and animal species, many of which are rare. The Onkaparinga River estuary also provides habitat for endangered migratory birds. You can go fishing in the river, wander along the wetland boardwalks, ride a bicycle on the shared use trails, walk your dog (on a lead), kayak the calm waters or just be at peace with nature.
Just next door, to the east of the recreation park, Onkaparinga River National Park boasts cliff top views, and deep gorges.
