Time Out says
Hart's Mill is part of a historic colonial industrial precinct in Port Adelaide that has been transformed into a community and cultural hub. In the area surrounding the mill you'll find an elaborate playground featuring geometric climbing frames, a rocket slide, mouse wheel, sandpit and interactive equipment designed to teach kids about the area's history as 19th-century working port. There are lawn areas for waterfront picnics, public barbecues, and space for markets. Nearby, the Folklore Café juts out over the water; you can tour street art along the Wonderwalls outdoor gallery; and burn off some steam along the 3.5km Anna Rennie Loop bike and walking path.
