GetYourGuide highlights the Duomo, The Last Supper, La Scala, Sforza Castle, Brera and Navigli — two days can link them without racing.
Day 1: centre
Start at the Duomo, walk through the Galleria toward La Scala and Brera, and keep the evening flexible.
Day 2: art and neighbourhoods
If The Last Supper is available, build the morning around the confirmed slot. Continue to Sforza Castle, the park and Navigli.
When to visit Como
Lake Como deserves its own day rather than a short add-on. Make it day three if Milan gets two days.
