Bernina Express · Tirano to St Moritz
The Bernina line climbs from palm-lined Tirano to a glacier pass at 2,253 metres and down to St Moritz — the highest railway crossing of the Alps, and one of the steepest that runs on plain wheel-to-rail adhesion, no cogwheel. It's a UNESCO World Heritage railway, and from Milan it makes a long, spectacular day. Here's how to do it.
The Alps, climbed without a cog
Most railways that climb high mountains cheat gravity with a rack — a toothed rail the train grips like a cog. The Bernina line doesn't. It crests the Alps at 2,253 metres and holds gradients up to seven percent on plain wheel-to-rail adhesion, making it the highest transalpine railway crossing and one of the steepest adhesion railways in the world. That engineering nerve — climbing the Alps on grip alone — is why the line, opened in 1910, still feels audacious, and part of why UNESCO listed it.
In 2008 UNESCO inscribed the Rhaetian Railway's Albula and Bernina lines as a World Heritage Site — recognition not of scenery alone but of how boldly the railway was built into an unforgiving landscape. The full Chur-to-Tirano Bernina Express route crosses, by the railway's own count, 196 bridges and 55 tunnels; the Bernina line itself, the part this day trip rides, has 52 viaducts and bridges and 13 tunnels and galleries, including the open 360-degree spiral of the Brusio viaduct, a stone loop built in 1908 purely to tame the gradient where the valley fell away too steeply.
The line's signature is its sheer range. In a single ride it drops from the ice of the Bernina Pass — past the Morteratsch and Palü glaciers and the turquoise, glacier-fed Lago Bianco — down through the Italian-speaking Val Poschiavo to palm-dotted, Mediterranean-flavoured Tirano, falling roughly 1,800 metres from the pass down to Tirano, which lies at about 430 metres. Glaciers to palm trees, in one afternoon, through the panoramic windows of a slow red train.
The climb
Nearly 1,800 metres of height gained on grip alone — no rack, no cogwheel — then the descent into the Engadine.
How the day runs
The day starts at a meeting point in central Milan; the booking calendar and your confirmation show the departure time. From there a coach drives north, over the border and up to St Moritz, so the first part of the day is road, not rail. The coach leg is long, so this is a day that starts before it feels finished.
In the afternoon you board the Bernina Express at St Moritz and ride south. The line climbs to the Bernina Pass, then descends past Alp Grüm and through the Val Poschiavo, dropping roughly 1,800 metres to Tirano by way of the Brusio spiral. The panoramic option guarantees a seat in a panoramic carriage, though seats are not assigned in advance.
The train crests the Bernina Pass at Ospizio Bernina, 2,253 metres, beside Lago Bianco, then passes Alp Grüm, where the Palü glacier stands above the valley. From there it descends into the Italian-speaking Val Poschiavo on its way to Tirano. Behind you is St Moritz, the resort credited with starting winter tourism in the Alps.
At Tirano the train ends, there is a short stop, and a coach takes you back to Milan, with a scheduled arrival in the late evening. Your free time in St Moritz comes earlier in the day, before the train, and meals and personal expenses in St Moritz or Tirano are not included. Some options replace the free time with a lunch at Diavolezza.
What passes the window
The Bernina line strings together a sequence of set-pieces between Tirano and St Moritz. Here's what to watch for.
Just above Tirano the line loops a full 360 degrees over its own tracks on a nine-arch stone viaduct, built in 1908 to hold the gradient where the valley dropped too fast for a straight climb. It's one of the most photographed pieces of railway in the Alps, and a flourish near the end of the ride — a graceful, open-air corkscrew rather than a hidden tunnel.
At the pass lies Lago Bianco, a turquoise, glacier-fed reservoir beside the summit station, sitting on the continental divide: water on one side drains to the Adriatic, on the other to the Black Sea. Its intense milky-blue colour comes from glacial rock flour, and it's the visual high point of the crossing, framed by peaks.
On the climb the line runs within sight of the Morteratsch glacier — one of the most accessible large glaciers in the Alps — and, from the celebrated Alp Grüm terrace at 2,091 metres, looks directly onto the Palü glacier and down the Val Poschiavo. These are the views that fog can steal, and that a clear day makes unforgettable.
Below the pass the line drops through the Val Poschiavo, an Italian-speaking Swiss valley of stone villages, terraced fields and the long Lago di Poschiavo, before reaching the border. This is the 'palm trees' end of the ride: in a single long descent the landscape falls from alpine ice to an almost Mediterranean warmth.
The Engadine resort at the line's northern end, on a lake at around 1,850 metres, is where alpine winter tourism was invented — on a hotelier's 1864 wager that summer guests would love the snow — and went on to host the Winter Olympics in 1928 and 1948. Glamorous, high and sunny, it's the day's turnaround point and its one real town.
The Italian rail town where the train ends, in the Valtellina wine valley. Its Italian and Swiss stations face each other across a single piazza — you walk from one country's railway to the other's — beside the Renaissance basilica of the Madonna di Tirano, built from 1505. The improbable meeting point of a Lombard valley and an Alpine railway.
A long day, told straight
From Milan the day runs about 12.5 hours, with several hours of coach each way before and after the train. The scenery is the point, not leisure time — you'll spend far more of the day moving than stopping. Come for the ride and the windows; if you want lingering time in St Moritz or the mountains, this is better as part of a longer Alpine trip than as a single dash from Milan.
The branded panoramic Bernina Express runs on compulsory seat reservations, separate from any rail ticket or pass — a detail that catches out independent travellers every day. On this Milan day trip the panoramic option includes a guaranteed seat in a panoramic carriage, though not a seat number assigned in advance. If you go independently, reserve well ahead, especially in peak season.
The line runs from Italy into Switzerland, so carry a valid passport or ID — passports are checked, and there's a small Italian police office at the Tirano station. Switzerland is in the Schengen area but not the EU and not the eurozone: it uses the Swiss franc, so bring francs or a card for spending in St Moritz, where change comes in CHF even if euros are accepted.
The train runs in all weather, but low cloud or fog at the pass can hide the glaciers and Lago Bianco, and a clear day is dramatically better than a grey one. You can't control the mountain forecast, so choose a flexible booking, and if your dates allow, favour a settled-weather day. Winter and summer both deliver — but a socked-in pass in any season is the one real disappointment to guard against.
Bernina or Glacier Express?
Reading the line
Two distinctions decide whether you end up on the ride you pictured. Both are easy to get right once you know them.
There's no direct scenic train from Milan itself — the day trip runs a coach up to St Moritz and then rides the Bernina Express down over the pass to Tirano, where a coach takes you back. Travellers occasionally expect to board the famous red train in Milan; you don't. What the packaged day gives you is the transfer to the line, a guaranteed panoramic carriage seat if you pick the panoramic option, and the border logistics handled, all in one booking.
The same scenic track is served both by the reservation-only branded Bernina Express, with its panoramic roof windows, and by ordinary regional trains with opening windows and no reservation. The scenery is identical; the experience and price differ. This Milan tour guarantees a panoramic carriage seat only if you pick the panoramic option — worth checking so you get the glass-roofed carriage you're picturing.
Winter or summer?
The postcard: a red train threading a white world, Lago Bianco and the pass under deep snow, the whole Engadine a fairy-tale of ice — and the small feat that the line stays open all winter at all. Days are short, so an early start matters, and snow can flatten the light; but for the classic 'red train in the snow' image, winter is the one. Dress for real cold at the pass.
The other face of the line: glaciers at their most exposed and dramatic, Lago Bianco a vivid turquoise, alpine meadows in flower, green valleys and palm-lined Tirano. It's the busiest season, so reserve well ahead, and the longer daylight gives you more scenery for your day. For glaciers-and-green contrast and the fullest views, summer is the pick.
A quieter shoulder: golden larches on the slopes, thinner crowds and easier booking, with the glaciers still visible before the deep snow arrives. Weather grows less settled, but a clear autumn day pairs the drama of the high peaks with the calm of the off-season — a fine time for travellers who'd rather not share the panoramic car.
The in-between season: melting snow high up, greening valleys below, and the fewest crowds of the year. Views can be mixed as the pass shakes off winter, and some settled-weather luck helps, but prices and demand are lower and the contrast between the still-white heights and the waking valleys is its own reward. A quiet, changeable, underrated time to ride.

Planning your day
Go in knowing this is a 12.5-hour day with real transit at each end, and the day becomes a pleasure rather than a surprise. Eat before the early start, bring snacks and water, and treat the coach legs as part of the journey. The reward for the long day is a stretch of the Alps you simply can't see any other way — settle in and let the windows do the work.
You cross from Italy into Switzerland, so bring a valid passport or ID — it's checked at the border. Switzerland isn't in the eurozone, so carry Swiss francs or a card for anything you buy in St Moritz; euros are sometimes accepted but change comes in francs. A little cash in CHF saves hassle for a coffee or lunch at altitude.
On this tour the panoramic seat is guaranteed only with the panoramic option, so check the option you pick to confirm you're on the branded Bernina Express or a reserved panoramic seat rather than a regional service. Reservations are mandatory on the branded train and sell out in peak periods, so book ahead — the whole convenience of the package is that this is handled for you.
It can be warm in Tirano and cold at 2,253 metres on the same afternoon, so bring layers and something warm even in summer — the pass and any photo stops are properly alpine. In winter, dress for real cold. Good footwear helps for the St Moritz free time, and sunglasses are worth having: high-altitude snow and glare are intense.
The single biggest variable is the mountain weather, which can hide the glaciers and Lago Bianco behind cloud. You can't book sunshine, but you can book flexibly: choose a tour with free cancellation, keep an eye on the Engadine forecast, and if you have any choice of dates, favour a settled one. A clear day on the Bernina line is worth arranging your plans around.

About 12.5 hours. The tour starts at a central Milan meeting point (your confirmation shows the time), takes a coach to St Moritz, gives you free time, then rides the Bernina Express over the Bernina Pass down to Tirano before the coach back. It's a genuinely long day where the scenery, not leisure time, is the point; you spend much of it moving. If you want more time in the mountains, it's better as part of a longer Alpine trip.
Yes — the route crosses from Italy into Switzerland and passports are checked, so bring a valid passport or ID. Switzerland is in the Schengen area but not the EU and not the eurozone: it uses the Swiss franc. Bring francs or a card for anything you buy in St Moritz — euros are sometimes accepted, but you'll get change in Swiss francs.
On the branded panoramic Bernina Express the seat reservation is mandatory and separate from any rail ticket or pass — a detail that catches out independent travellers. On this Milan day trip the panoramic option includes a guaranteed seat in a panoramic carriage; seats are not assigned in advance. If you travel independently, reserve well ahead, especially in peak summer and over the winter holidays.
No — they're different trains and routes on the same Rhaetian Railway network. The Bernina Express runs Chur or St Moritz to Tirano in Italy, crossing the high Bernina Pass on adhesion; the Glacier Express runs Zermatt to St Moritz, a full day's ride, and does not enter Italy. They meet near St Moritz, which is why people combine them, but only the Bernina Express is the one reachable from Milan via Tirano.
Both are spectacular and it runs year-round. Winter gives you the classic red-train-in-snow scene, deep snow at the pass and a fairy-tale Engadine, with short days. Summer gives you exposed glaciers, turquoise Lago Bianco, green valleys and long daylight, but the biggest crowds — book ahead. Autumn brings golden larches and calm; spring is quiet and changeable. Choose winter for snow, summer for glaciers and green.
The train runs in all weather, but low cloud or fog at the pass can hide the glaciers and Lago Bianco, and a clear day is far better than a grey one. You can't control the mountain forecast, so book a tour with free cancellation, watch the Engadine weather, and favour a settled-looking day if your dates allow. A socked-in pass is the one real disappointment to plan against.
