No, the trams in Milan are not free. They are part of the ATM (Azienda Trasporti Milanesi) integrated transport system, which also includes the Metro and city buses. To ride a tram, you must have a valid ticket or use a contactless payment method. In 2026, the most convenient way to pay is by tapping your contactless credit card or smartphone on the readers found on board the newer trams or at the station platforms for older ones. A single ticket typically costs around €2.20 and is valid for 90 minutes of travel across the entire network, allowing you to switch between trams and the Metro. You can also purchase 24-hour or 48-hour passes if you plan on doing extensive sightseeing. It is a common mistake for tourists to think the vintage 1920s-style "Class 1500" trams (like those on Line 1) are free museum pieces—they are active commuter vehicles, and fare inspectors frequently board to check for tickets. Getting caught without a validated ticket results in a hefty on-the-spot fine, so always ensure you have "tapped in" correctly before the tram starts moving.
