Starting from the Gate 12 car park on River Road, Noarlunga Downs, this walk explores the Onkaparinga River Estuary via the Noarlunga Downs Wetland Trail. This trail showcases a significant environmental restoration project that involved planting thousands of native seedlings from locally-sourced species, transforming the area from a sludge lagoon into a thriving wetland sanctuary for native plants, animals and birds. The site consists of a series of interconnected ponds that treat stormwater before it enters the Onkaparinga River. Along the trail, walkers can learn about the significance of the estuary to its traditional owners via the interpretive signs that feature artwork by contemporary Aboriginal artist Paul Herzich. This walk consists of flat, compacted gravel paths and boardwalks, suitable for walkers and cyclists of all fitness levels, as well as prams and wheelchairs. The trail is accessible either from the main car park, which has picnic facilities, barbecues and toilets, or from the car park at the western end of the boardwalk, which shortens the walk. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
