How long does the Glacier Express take?

The exact duration varies by timetable and season, so check current schedules with Matterhorn Gotthard Bahn. It's a long journey by design, running the full distance between St. Moritz and Zermatt at a deliberately unhurried pace.

Do I need to book in advance?

It's strongly advisable, particularly in busier periods, since seats can fill up. Book through Matterhorn Gotthard Bahn rather than assuming availability on the day.

Which class should I choose?

It depends on whether you want extra comfort and onboard service included, or a simpler experience at lower cost. Both classes share the same panoramic windows and the same route, so the scenery isn't the differentiator, the comfort level is.

Is there a best side of the train to sit on?

Not really, because the route curves through valleys on both sides over the course of the journey. Panoramic windows mean you see plenty from either side, and swapping seats partway through is a good way to cover both.

What's the best time of year to travel?

It depends what you want from the Alps. Winter gives dramatic snow-covered scenery, summer offers greener valleys and longer daylight, and spring/autumn tend to be quieter with their own particular light on the mountains.

Glacier Express, Switzerland — train travel guide

Overview

Call it the world's slowest express and you're not being unkind, you're describing the entire point. The Glacier Express doesn't hurry between St. Moritz and Zermatt, and it has no interest in pretending otherwise. This is a train built around the view out of the window, not the clock on the wall.

It crosses the Swiss Alps from one celebrated resort to another, threading valleys, gorges and high passes that most travellers would otherwise only see from a car park or a hiking trail. You sit still, the landscape does the work.

It's not a budget option and it's not a quick way to get anywhere. It's a journey sold entirely on its own terms, and for the right traveller that's exactly the appeal.

The route: St. Moritz to Zermatt

The line runs across Switzerland's alpine spine, connecting the smart, high-altitude resort of St. Moritz in the east with Zermatt, home of the Matterhorn, in the south-west. Between the two lies a long, unbroken stretch of proper mountain terrain: valleys, forested slopes, high open ground and villages that only make sense once you've seen how remote they are from the train window.

The character of the journey changes as it goes. There are sections where the train climbs steadily through switchback terrain, stretches where it runs along valley floors flanked by peaks, and moments where the scale of the landscape simply dwarfs the train itself. It's less a single view than a slowly unfolding sequence, which is exactly why the journey takes as long as it does.

Timetable and booking

Services operate seasonally, and frequency, timing and availability all shift across the year, so there's no substitute for checking directly with Matterhorn Gotthard Bahn before you plan anything else around this trip. Don't assume a service you took one year runs at the same time or even at all the next.

Because the route is popular with both leisure travellers and photographers chasing the scenery, seats can be tight in peak periods. Booking ahead through the operator is the sensible approach rather than turning up and hoping. If you're building a wider Swiss itinerary around this train, treat the Glacier Express timings as the fixed point and build everything else around them, not the other way round.

Fares and classes

The Glacier Express typically offers a choice of classes, and the difference is really about comfort and inclusions rather than the view itself, since the panoramic windows run the length of the carriage regardless of where you're sitting. The higher class of travel generally means a roomier, quieter cabin experience and often bundles in onboard service such as at-seat dining, so you're not queuing or juggling trays on a moving train through mountain terrain.

The other class trades some of that extra comfort for a lower cost, while still giving you the same enormous windows and the same scenery outside them. Neither class changes the route or the pace, so the choice really comes down to how much you value being looked after versus keeping costs down. For exact fares and what's included, that's one for Matterhorn Gotthard Bahn directly, not for guesswork.

Which side to sit for the best views

On a journey this long, side of the train matters, but it's not a simple one-side-fits-all answer, because the line curves through so many valleys that the best outlook swaps from left to right and back again over the course of the trip. The honest advice is to accept that neither side is wrong: you'll get spectacular views from both, just at different points in the journey.

If you're travelling with a companion, it's worth swapping seats partway through, or simply standing in the vestibule area for a few minutes at the points where the train slows for tighter curves, which tends to happen at the most dramatic stretches of track. Panoramic windows mean you lose very little by being on the 'wrong' side anyway, so don't spend the whole journey anxious about it.

The onboard experience

The signature feature is the panoramic glazing: large windows, often extending up into the roofline, designed specifically so passengers can take in the scale of the mountains without craning their necks. This is a train built for looking outward, and everything about the carriage layout supports that.

Catering is part of the experience rather than an afterthought, with food and drink service available on board so you can eat while watching the landscape pass rather than breaking off the journey to find something to eat at a stop. It suits the pace of the whole trip: unhurried, scenic, and designed to be enjoyed from your seat rather than rushed through.

Best time to travel

The Alps look entirely different depending on the season, and the Glacier Express experience shifts with them. Winter brings snow-covered peaks and a crisp, dramatic look to the high passes, which suits the route's reputation as a proper alpine adventure, though weather can affect conditions and visibility.

Summer opens up greener valleys, more daylight for the journey, and generally more settled conditions for enjoying the views in comfort. Spring and autumn sit between the two, often with fewer crowds than the height of summer or the ski season, and their own particular light on the mountains. There's no single 'right' season, more a choice of which version of the Alps you want to see.

Onward travel from Zermatt

Zermatt itself is a car-free resort, so onward travel is generally by rail or by the local means the town itself provides, and it's well used to visitors arriving specifically off the Glacier Express and needing onward connections. It functions as a natural end point for a mountain crossing rather than just a through-station.

From Zermatt, travellers typically continue their Swiss or wider European rail journey by connecting onward through the regular Swiss rail network, so it's worth checking Matterhorn Gotthard Bahn or the wider Swiss rail operators for how your onward leg fits with your Glacier Express arrival time.

A little history

The Glacier Express grew out of Switzerland's long-standing tradition of alpine railway engineering, at a time when connecting remote mountain resorts by rail was as much a feat of ambition as of practical transport. It has since become one of the country's signature named trains, run by Matterhorn Gotthard Bahn as a showcase for the scenery rather than a fast point-to-point service.

Over time it has shifted from a functional link between two resort towns into something closer to a journey in its own right, the kind of train people book specifically to be on, rather than simply a way of getting from St. Moritz to Zermatt. That reputation is now central to how it's marketed and experienced today.
