This artificial lake near Linate airport was originally built in 1930 as a hydro-plane airport; it’s now effectively part of Milan’s parks, but more of a mini Riviera. Spread over 8km2, this leisure park is half in the woods and half on the lake, measuring 2.5km long and 5km wide and filled with clean, cold Lombardy spring water lined with sandy beaches. From the beginning of April till the end of October, Idropark Fila (or Idroscalo as it is still known, pre-Fila sponsorship) is Milan’s summer playground, with watersports (canoeing, rowing, water- skiing, swimming and sailing – on rare breezy days), mountain biking, blading, tennis, climbing and cross country running. By night, it’s packed out with cool kids (and mosquitoes) as Milan’s nightlife migrates from the city centre to Idroscalo’s bars, restaurants, clubs and big-name concerts. Clubs of note are Cafe? Solaire, Papaya Beach Club and Punta dell’Est. Thanks to Linate’s air traffic, there are plenty of plane-spotting opportunities. Ice skating is available in the winter.
