Milan rewards visitors who move fast, and the open-top hop-on hop-off bus is built exactly for that pace. In a single day you can loop past the Duomo, Castello Sforzesco, the Navigli canals and San Siro Stadium without ever hunting for a tram stop.
City Sightseeing Milano runs the city’s main hop-on hop-off network, with buses covering four separate routes from a shared handful of central stops. It is the kind of ticket that suits a tight itinerary far better than working out Milan’s tram map from scratch.
The appeal is simple: you buy one ticket, hop on near the Duomo or Castello, and hop off wherever something catches your eye. An onboard audio guide fills in the history of each landmark while you ride the open top deck between stops.
It will not replace the metro for a week-long stay, and it will not get you closer to the Last Supper than the pavement outside Santa Maria delle Grazie. But for a first full day in the city, it is a genuinely efficient way to see the skyline, the stadium and the canal district in one loop.
This guide covers the actual routes and stops, current ticket pricing across the 24, 48 and 72 hour options, who the bus genuinely suits, and the practical details that make the difference between a smooth ride and a wasted morning. We have checked prices and stop lists against both operators directly, so nothing here is guesswork.
Whether you are flying in for a long weekend or building a longer Milan itinerary around day trips to Lake Como or the ski resorts, the hop-on hop-off bus works best as a first-day orientation tool rather than your only way of getting around. Read on for the detail before you decide whether to buy.
| Line | Nickname | Key Stops | Approx. Loop Time |
|---|---|---|---|
| Line A | Red | Castello Sforzesco, Duomo, Teatro alla Scala, Moscova | ~50 minutes |
| Line B | Blue | Duomo, Teatro alla Scala, Stazione Centrale, Porta Venezia | ~50 minutes |
| Line C | Green | Castello Sforzesco, San Siro Stadium, Parco Sempione | ~80 minutes |
| Line D | Yellow | Castello Sforzesco, Navigli, Brera, Duomo, Teatro alla Scala | ~75 minutes |
City Sightseeing Milano: How the Hop-On Hop-Off Network Works
City Sightseeing Milano operates the city’s established open-top bus network, running four numbered lines out from a cluster of central stops near the Duomo and Castello Sforzesco. Buy one ticket and it covers every line for the duration you choose, not just the route you board first, with the current timetable, route map and full ticket pricing covered in detail below.
Each bus has an open upper deck for photos and a covered lower deck for when the weather turns, plus a recorded commentary piped through onboard speakers or earphones. The operator currently advertises commentary in ten languages, with additional child-friendly commentary on board, so check the current language list if that matters for your group.
The core idea is flexibility rather than a fixed tour time. You get off at Castello Sforzesco, spend an hour in the park, then simply board the next bus on the same line when it comes round. There is no need to finish a loop in one sitting, which is the entire point of the format.
Buses run at fairly frequent intervals, typically every 20 to 30 minutes depending on the line, so waiting times are usually short. Between April and September, City Sightseeing also runs a separate seasonal night tour, a single fixed loop departing in the early evening from Largo Cairoli.
Tickets can be bought online in advance or directly from the driver or a kiosk on the day, though buying ahead avoids any queue at the main stops in peak season.
Line A (Red): Castello Sforzesco, Duomo and Teatro alla Scala
Line A, the red route, is the closest thing to a greatest-hits loop. It links Castello Sforzesco, the Duomo and Teatro alla Scala before swinging north through Moscova, and at around 50 minutes it is the quickest full circuit to complete. Because it touches the three most photographed stops in the centre, it tends to be the line most first-time visitors ride first.
Best for a short trip. Compare rooms by neighbourhood, price and guest rating before you book.
Compare hotelsBest for longer stays. Whole apartments and houses, so you are not eating out three times a day.
View rentalsBest for double-checking. Runs the same Milan search across several booking sites so you are not leaving money behind.
Compare pricesLine B (Blue): Stazione Centrale and Porta Venezia
Line B, the blue route, shares the Duomo and La Scala stops with Line A but heads east instead, passing Stazione Centrale and the leafy Porta Venezia district. It is the better choice if you are arriving by train and want to start sightseeing straight from the station, since it picks passengers up close to the platforms rather than requiring a walk into the centre first.
Line C (Green): San Siro Stadium and Parco Sempione
Line C, the green route, is the one football fans should track down, since it is the only line running out to San Siro Stadium via Parco Sempione. At roughly 80 minutes it is the longest loop, reflecting the extra distance out to the stadium and back, so anyone with a match or stadium tour booked should build that extra time into their day.
Line D (Yellow): Navigli and Brera
Line D, the yellow route, is arguably the most rewarding for a first-timer with a full day free, since it is the only line that reaches both the Navigli canal district and the Brera art quarter before looping back through Duomo and La Scala. Because all four lines share stops at Castello Sforzesco and the Duomo, switching between routes mid-visit is straightforward, and most visitors end up mixing two or three lines across a day depending on where the mood takes them.
City Sightseeing Milan: Ticket Options and Pricing
City Sightseeing Milano sells tickets in 24, 48 and 72 hour blocks, with the clock starting from first use rather than from purchase. A 24 hour adult ticket typically starts from around €24 (£21/$26), which is enough time to comfortably ride two lines in one day.
Stepping up to 48 hours generally costs in the region of €28 to €30 (£24 to £26/$30 to $32), and a 72 hour pass usually runs to roughly €32 to €35 (£28 to £30/$34 to $38). The longer passes make far more sense if San Siro, Navigli and the Duomo area are all on your list, since covering all four lines properly rarely fits into a single day.
Children between around 5 and 15 years old typically pay a flat reduced rate of about €10 (£9/$11) regardless of which duration the accompanying adult chooses, and younger children usually ride free. Every ticket includes the multilingual audio guide and disposable earphones, plus onboard Wi-Fi and USB charging points on most buses.
Booking online in advance locks in the current rate and, in many cases, a modest discount over the walk-up price. The easiest way to book directly is through the ticket below:
Gray Line Milan: A Second Hop-On Hop-Off Network
Gray Line runs Milan’s second hop-on hop-off network, a simpler two-line service built around the historic centre rather than the wider four-line spread City Sightseeing covers. Both routes start and finish at Piazza del Duomo, and a full loop on either line takes roughly 1 hour 50 minutes door to door.
Gray Line’s Red Route: Duomo and Galleria Vittorio Emanuele II
The Red Line sticks closest to the postcard sights, threading past the Duomo and the Galleria Vittorio Emanuele II before working its way through the surrounding streets of the historic core and back to Piazza del Duomo. It is the more obvious pick for a first-time rider who wants the classic view of the centre in one loop.

Book a transferGray Line’s Blue Route: A Second Loop of the Historic Core
The Blue Line covers a second slice of the centre from the same starting point, giving riders a different look at the streets around the Duomo without needing to buy a separate ticket or plan a connection between routes. It suits anyone who has already ridden the Red Line and wants to see more of the historic core on the same pass.
Onboard commentary runs to roughly ten languages, including English, Italian, French, Spanish, German, Portuguese, Russian, Chinese, Japanese and Arabic, with dedicated children’s commentary available in English, Spanish and Italian.
Gray Line advertises buses roughly every 25 to 45 minutes, though it is worth being honest about the gap between marketing copy and the road. Independent traveller reviews on TripAdvisor commonly report longer real-world waits, sometimes 30 minutes to over two hours at busy times, along with occasional route deviations, so build in some slack rather than timing a tight itinerary around the advertised interval.
Pricing starts from around €26 (£23/$29) for a single ticket, making it one of the cheaper hop-on hop-off options in the city centre. Book the Gray Line ticket directly below:
City Sightseeing or Gray Line: Which Milan Bus Suits You
| Operator | Lines | Coverage | Loop Time | Starting Price |
|---|---|---|---|---|
| City Sightseeing | 4 (A, B, C, D) | Duomo, Castello Sforzesco, San Siro Stadium (Line C), Navigli and Brera (Line D) | ~50 to 80 minutes per line | €24 (£21/$26) |
| Gray Line | 2 (Red, Blue) | Duomo, Galleria Vittorio Emanuele II and the surrounding historic core | ~1 hour 50 minutes per line | €26 (£23/$29) |
The honest answer depends on what is actually on your list. City Sightseeing’s four lines are the better fit if San Siro Stadium or the Navigli canals are part of your plan, since Gray Line’s two routes stay centred on the Duomo and never reach either. Gray Line, in turn, suits anyone who wants a simpler, shorter loop of the historic core without paying for stops they will not use, though it is worth weighing that against the longer real-world waits some riders report.
Hop-On Hop-Off Versus Walking or the Metro
Milan’s historic centre is genuinely walkable, and the stretch between the Duomo, La Scala and Castello Sforzesco takes barely 15 minutes on foot. For that inner core alone, walking or the metro’s efficient network, run by ATM Milano, will usually get you there faster than waiting for a bus.
Where the hop-on hop-off format earns its ticket price is distance and orientation rather than raw speed. Getting to San Siro Stadium or looping through the Navigli canals on foot eats up a chunk of the day, while the bus covers both without you needing to work out tram routes or ticket zones.
There is also a genuine comfort factor for anyone dealing with tired legs, small children or hot weather. Sitting down on an open-top deck between stops is a different experience to standing on a crowded tram, even if the tram itself is cheaper and often quicker point to point.
The honest comparison is cost versus convenience. A single ATM metro or tram ticket costs a couple of euros, so anyone confident navigating public transport for a few days will save money doing exactly that, particularly if they are staying in Milan longer than 48 hours.
For a first morning spent getting oriented before switching to the metro for the rest of the trip, though, the bus does a genuinely useful job that a map alone cannot replicate.
Who a Milan Hop-On Hop-Off Bus Suits (and Who Should Skip It)
The hop-on hop-off bus is at its best for time-pressed visitors on a short stopover, families juggling small children, and anyone visiting Milan for the very first time who wants a low-effort way to see the main sights in a day or two.
It also suits football fans making a dedicated trip out to San Siro, since Line C removes the guesswork of connecting buses or trams to reach the stadium from the centre. Same goes for anyone keen to see Navigli and Brera without spending an afternoon working out the walking route between them.
Where it makes less sense is for anyone staying a week or longer who plans to explore at a slower pace, since the daily ticket cost adds up fast against a handful of cheap metro fares. Confident independent travellers who enjoy figuring out a city’s transport network on foot will likely find the bus more restrictive than helpful.
It is also not the right choice for anyone whose priority is getting inside specific sights rather than seeing them from the road. The bus passes Santa Maria delle Grazie and San Siro but does not include entry tickets, so Cenacolo Vinciano viewings and stadium tours still need booking separately.
In short: brilliant for orientation and covering ground on day one, less useful once you already know where you are going.
Practical Tips for Getting the Most From Your Ticket
Board earlier in the day if possible. Mid-morning departures tend to be less crowded than the after-lunch rush, and you will get first pick of upper deck seating for photos of the Duomo’s spires.
Check the weather before committing to the open top deck. Milan’s summers can be genuinely hot with little shade up top, while spring and autumn showers make the covered lower deck the more comfortable option on a damp day.
Buying online in advance is generally quicker than queuing at a kiosk, especially around the main Duomo stop in high season, and it lets you start the clock on your ticket exactly when you plan to begin sightseeing rather than losing time at the ticket window.
If San Siro Stadium is a priority, check the current timetable for Line C before you set off, since it runs less frequently than the central loops and skipping the stop you wanted can cost the best part of an hour waiting for the next bus.
Finally, pair the bus with some walking rather than relying on it exclusively. Hopping off at Castello Sforzesco or Navigli and wandering for half an hour before rejoining the route tends to make for a far more memorable day than staying seated for the whole loop.
Rupert’s Handy Travel Tips
I have watched plenty of visitors climb aboard the Milan open-top bus looking a little unsure where to start, so here is what I would tell them before they buy a ticket.
- Sit upstairs early: the front rows on the open deck fill up fast once a tour group boards, so get there before the queue builds.
- Bring a layer: the open top deck feels breezier once the bus is moving, even on a warm Milan afternoon.
- Match the line to your plan: only Line C reaches San Siro and only Line D reaches Navigli, so check the map before you commit a whole afternoon.
- Charge your phone first: onboard USB ports exist but are not guaranteed to be free, and you will want battery for photos from the top deck.
- Keep your ticket handy: you will need to show it each time you re-board, even on the same line you started on.
