The Grand Train Tour of Switzerland: Chasing the Alps from a Panoramic Window

There is a particular kind of stillness that settles over a carriage when the Eiger first appears through a curtain of larch trees, or when the Landwasser Viaduct swallows the train whole into its own tunnel mid-arc, 65 metres above the valley floor. No steering wheel, no parking search, no eyes torn between the road and the view. For a country built on vertical terrain, Switzerland solved the traveller’s oldest dilemma — drive or look — by simply removing the choice. You sit back, and the Alps do the rest.

The Grand Train Tour of Switzerland is not a single train but a curated 1,280-kilometre loop stitched together from the country’s most celebrated panoramic routes: the Glacier Express, the Bernina Express, the GoldenPass Line, and several connecting regional services. Officially signposted since 2015, it links eight of Switzerland’s UNESCO World Heritage sites and both cultural capitals, Geneva and Zurich, into one continuous, bookable journey. You can ride it in eight days or in three; you can do it entirely by rail pass, hopping trains at will, or reserve specific panoramic services for the marquee legs.

The Big Three: Glacier Express, Bernina Express, GoldenPass

The Glacier Express, running between Zermatt and St. Moritz, is the one every list opens with, and for good reason. At roughly 7.5 hours and 291 bridges, it is less a transfer than a ceremony — floor-to-ceiling windows, a dining car serving a genuinely good three-course lunch, and a soundtrack of nothing but wheels on rail as you cross the Oberalp Pass at 2,033 metres. It’s the slowest way to cover that distance in Switzerland, and that’s precisely the point.

The Bernina Express does something no other train in the Alps does: it connects a glacier to a palm tree. Departing Chur or St. Moritz, it crosses the Bernina Pass at 2,253 metres — the highest point reached by any adhesion railway in Europe, no cog-wheel assistance required — past the Morteratsch Glacier, then descends through the spiralling Brusio viaduct into the Italian-speaking, palm-lined streets of Tirano. Two climate zones, one ticket.

The GoldenPass Line, the newest of the trio to run as a single seamless service (since 2022), links Lucerne to Montreux via Interlaken and the Simmental valley, closing what was for decades an awkward three-train transfer with track-gauge changes. It trades high-altitude drama for something gentler: green pastures, timber chalets, and a final glide along Lake Geneva with the Château de Chillon rising from the water.

Beyond the Headliners

Skip the Bernina and GoldenPass at your peril, but the tour’s quieter legs reward patience. The Voralpen Express between St. Gallen and Lucerne threads through rolling pre-Alpine hills that feel almost Irish in their green. The Centovalli Railway, connecting Locarno to Domodossola in Italy, crosses more than 80 bridges and tunnels through granite gorges thick with chestnut forest — a route locals rate above some of the famous ones precisely because so few tourists know it.

Planning It Right

A few things separate a good Grand Train Tour experience from a merely fine one:

• Book panoramic seats early, especially in summer. The Glacier Express and Bernina Express require seat reservations even with a valid rail pass, and the best window seats — right-hand side heading from Zermatt, for what it’s worth — sell out weeks ahead in July and August.
• Shoulder season has an edge. Late September and October bring golden larches against still-white peaks, thinner crowds, and clearer light for photography than the hazier summer months.
• A Swiss Travel Pass changes the calculus. It covers most GoldenPass and Voralpen Express travel outright and gives meaningful discounts on the Glacier Express and Bernina Express seat reservations, which is where the real cost sits.
• Don’t try to do it in one push. The tour is designed as a loop you dip in and out of. Basing yourself in Zermatt, Lucerne, and St. Moritz for two or three nights each — rather than living out of a suitcase on trains daily — leaves room for the hikes, lifts, and viewpoints that the train only ever shows you from a distance.

Why It Works

What makes the Grand Train Tour more than a scenic gimmick is Swiss rail’s underlying precision: connections are built to actual minutes, not approximate windows, and the infrastructure — those viaducts, spiral tunnels, and rack railways carved into the rock over a century of engineering — was built to last, not to impress. The theatre is a side effect of function.

For a traveller planning an Alpine itinerary, the tour is also a useful spine to plan around: pick two or three legs, anchor your stays at the towns along the route, and build day trips — a lift up to a viewpoint, a lakeside afternoon, a mountain restaurant — into the gaps between train days. The window seat, as it turns out, is only half the story. The other half is what you do when you finally step off.
