Once the liquid landing strip for seaplanes, this artificial lake is now a summer playground. Concerts regularly take place here, including indie-leaning festivals, and there’s swimming and water sports including wakeboarding and kitesurfing. Check the website for details and a weekly calendar of events. Like its fellow little ‘waterfront’, Navigli, mosquitoes come to play, too – make sure you have good insect repellent.

To get to Idroscalo, take bus 73 from Via Gonzaga to Linate Airport.
