• Swimming for strong swimmers: the city recommends swimming here only for experienced swimmers, so younger kids are better off on the lawns and playground
• Nude bathing at the tip: naturist bathing is allowed at the Inselspitz, the island's far end, worth knowing before you pick a picnic spot
• Grill spots and a restaurant on the island, so a picnic dinner by the water takes little planning

Werdinsel is an island of about eight hectares in the Limmat, between the river and a power-station canal. Once a parking lot and a car scrapyard, it is now open lawns with a playground, a soccer field, public grill spots, a restaurant and an accessible toilet.

The Flussbad Au-Höngg river bath sits here, using the old Strickler spinning mill from 1817 as its changing rooms.
