Milan has the most useful metro in Italy and a reputation as the country’s least interesting city. The first is true. The second comes from people who spent four hours between the Duomo and the station.
Five lines — M1 red, M2 green, M3 yellow, M4 blue and M5 lilac — and a compact city. After Rome the feeling is relief: almost everything you will want to see has a stop less than ten minutes’ walk away.
The centre is organised in rings around the Duomo. Inside the first is almost all of the postcard; the second is where the city gets genuinely interesting — Navigli, Isola, Porta Venezia — and there the metro is what decides whether you see two neighbourhoods or five.
The only trap is financial: in Milan you have to tap out as well if you pay contactless. If you do not, the system charges you the maximum fare.

The Duomo included, because skipping it would be odd, but not first.
Everything above you can do on your own with this page open. This other thing we build for you: the same idea as always — you do not know what you got until the day before — applied to Milan.
You choose where you fly from and where you are going, and we tell you what the adventure costs and roughly what getting there would cost. Flights and accommodation you book yourself: we are not a travel agency and we do not want to be.
The whole city sits in the same fare zone (Mi1–Mi3), so the urban ticket covers any journey inside Milan.
With the €7.60 daily cap on card, the three-day pass (€15.50) only pays off if you make more than two journeys a day on all three days. We ended up paying per journey.
If you want it line by line — which stations each one has, what is around every stop and how to work out a specific journey — we have all of it at our guide to the Milan metro. It is one of the sites we publish ourselves, and it is free.
Milan has three airports and the usual one for international flights is Malpensa, which is genuinely far out: 50 km.
It is worth two days. The boring reputation comes from most people only seeing the Duomo and the Galleria, which is the least interesting part. Navigli, Brera, the Cimitero Monumentale and Fondazione Prada change the impression a good deal.
€2.20 for the urban ticket, valid 90 minutes. Paying contactless is the same price per journey and never goes above €7.60 a day. You have to tap out as well.
Practically not. Thirty-five people per slot and tickets sell out months ahead. The odd last-minute space is released on the official site, but counting on it is risky.
Regional train from Cadorna (to Como Nord Lago, which leaves you on the promenade) or from Centrale (to Como San Giovanni). About 40–60 minutes depending on the train. It is the easiest day trip from the city.
This is what we do when we travel. The other thing we do is build adventures where you do not know which activity you got until the day before.
