Since leading our first tour to Switzerland in 1977, Great Rail Journeys has become the experts in Swiss travel. This spellbinding country is full of majestic mountains, vast glaciers, turquoise lakes and iconic railways that make Switzerland one of our most popular destinations. That said, I'd never been.
In January 2026, I got the opportunity to experience some of the greatest Swiss rail journeys that are highlights of many of our tours, including our GoldenPass, Mont Blanc & Jungfrau Express.
The standout moment for me was being on the "Top of Europe," Jungfraujoch, which overshadows the nearby Eiger. On a clear winter's day, I was at peace in my own world, looking out over what felt like the whole of Europe.
Climbing to the "Top of Europe"
An unforgettable alpine journey unfolds en route to the celebrated "Top of Europe," Jungfraujoch. We travel on incredible Swiss railways and utilize cutting-edge cableway engineering to reach this location high above the Bernese Oberland, where we enjoy some of the most dramatic high-mountain scenery in Europe.
Interlaken to Grindelwald
The day begins with a leisurely train ride from Interlaken into the nearby mountains, following the valley as steep slopes and dense forests close in around the line. Snow-topped traditional chalets with bells hung up for grazing cattle and frozen waterfalls create an increasingly alpine atmosphere as the train climbs toward the historic mountain resort of Grindelwald, framed by the imposing north face of the Eiger.
Eiger Express to Eigergletscher
At Grindelwald, the journey switches from rails to cable as we board the Eiger Express, a state-of-the-art tri-cable gondola designed to bring the high Alps dramatically closer. Over the 20-minute, four-mile ascent, the gondola's panoramic windows deliver uninterrupted views of the Eiger's sheer north wall, glaciers clinging to its flanks and the deep valley dropping away beneath our feet.
Jungfrau Railway to the summit
From Eigergletscher station, the famous Jungfrau Railway takes over, climbing through the heart of the mountains to Jungfraujoch, the highest railway station in Europe. Much of the route runs in the tunnel, but the train pauses at viewing windows carved into the rock, offering surreal glimpses out over the ice fields and cliffs that surround the line. I got the chance to stand at the front of the train, traveling through the tunnel as it climbs to the top at a gradient of up to 1 in 4.
Jungfraujoch and the Aletsch Glacier
Stepping off at Jungfraujoch, you enter a world of year-round snow and ice, with crisp air and far-reaching views across a vast sea of peaks. Walking through ice tunnels is an incredible experience; I could see a thin layer of black marbling that I was informed was put down decades ago to slow the ice from melting. A short walk brings you to the famous Sphinx Observatory, where outdoor terraces look directly onto the Aletsch Glacier, a UNESCO World Heritage site that flows in a broad, frozen river of ice as far as the eye can see. Tame alpine choughs that look like crows wander around the platform with a backdrop of glaciers.
Descent via Kleine Scheidegg and Lauterbrunnen
After time to explore the summit complex, visit ice exhibits and enjoy a trip into the Ice Bar, the descent begins by retracing the Jungfrau Railway back to Eigergletscher. Downhill trains on this line use regenerative braking and typically recover about half the energy that was needed for the uphill climb. From Eigergletscher, the train winds down to Kleine Scheidegg, a classic mountain pass station ringed by frozen pastures and dominated by the Eiger, Mönch, and Jungfrau above. We then continue via the Lauterbrunnen Valley, with the line threading between towering cliffs and icy waterfalls before emerging onto snow-covered plains near Interlaken.
GoldenPass Express from Interlaken to Montreux
Many moons ago, I traveled on Amtrak across the Appalachian Mountains - the only time I've had the opportunity to be in a viewing cabin onboard a train.
Switzerland's GoldenPass Express is a highlight in itself, with ultra‑modern panoramic carriages that give you front‑row views of Swiss chalets, glittering lakes and soaring peaks as it weaves from Interlaken to Montreux. It is a true "windows‑wide‑open" introduction to Switzerland at its scenic best and a favorite feature for many of our customers.
From Interlaken toward Lake Thun
Leaving Interlaken Ost, the GoldenPass Express first follows the Aare River before reaching the deep blue expanse of Lake Thun, with classic views of pyramid‑shaped Mount Niesen rising above the shore.
On this stretch, the landscape feels open and airy. Water, wide skies and boats on the lake set against the Bernese Alps give a great introduction to the journey.
Through Simmental and alpine villages
Beyond Spiez, the route turns into the Simmen Valley, where the character shifts from glistening lake views to a narrow green valley, with wooden chalets and neatly kept farms framed by rugged peaks.
Here, the train criss-crosses the River Simme, passing small villages and traditional houses with carved façades, before climbing toward Zweisimmen at the heart of the Bernese Oberland. In January, most of this route was blanketed by snow.
Changing gauge at Zweisimmen
Zweisimmen is where the line historically split between standard‑gauge (Interlaken-Zweisimmen) and meter‑gauge (Zweisimmen-Montreux). It's now the scene of a remarkable piece of railway engineering.
Instead of asking passengers to change trains, the GoldenPass Express uses variable‑gauge bogies and a special ramp. As the coaches roll slowly (around 9 miles per hour) over the installation, the wheels slide from 3.2 feet to 4.7 feet apart, and the coach body is lifted to match the different platform height. The locomotives are also switched to suit the change in voltage and network.
Into the high Alps toward Gstaad
After Zweisimmen, the meter‑gauge section climbs to the highest point of the route, at more than 4,100 feet above sea level. The scenery changes into classic high‑alpine pastures, barns and distant snow‑covered summits.
As the mountains begin to encroach closer to the track, the GoldenPass Express weaves through the famous resort of Gstaad and neighboring villages, where church spires and chalet roofs sit in a bowl of frozen meadows and snow-laden forested slopes.
Descent to Montreux beside Lake Geneva
Beyond Gstaad and Château-d'Œx, the line begins its long descent through the Gruyère region, where the scenery softens into rolling hills, forests and increasingly frequent glimpses of vineyards.
On the final approach, the train twists through vine-clad terraces high above Lake Geneva before suddenly revealing Montreux and the Swiss Riviera below. This contrast of sunshine, palm‑lined promenades and vine‑covered slopes feels a world away from glacial lakes and towering peaks where the journey began.
Exploring chocolate-box Swiss towns
Tracing a number of our tours, I stayed in Interlaken, Grindelwald, Montreux, and Vevey - each offering a distinct flavor of Switzerland, from high‑alpine drama to lakeside elegance. All are perfect stops on any of our Swiss rail itineraries, with hotels conveniently located near super-efficient and integrated transport hubs.
Interlaken
Interlaken sits on the flat plain between Lake Thun and Lake Brienz, with the Jungfrau massif perfectly framed at the end of the main promenade, the Höheweg. It feels like a classic resort town and a natural base for excursions into the Bernese Oberland, from lake cruises to funiculars.
Grindelwald
Grindelwald is an alpine village tucked beneath the north face of the Eiger, where traditional chalets, grazing pastures and easy access to high‑level cableways create a quintessential mountain resort - one of the oldest in Europe.
In summer, it is all about hiking, cliff walks and glacier gorges; while in winter, it shifts seamlessly into a busy ski and snow sports center.
Montreux
Montreux stretches along the sunny "Swiss Riviera" shore of Lake Geneva, backed by steep, vineyard‑covered slopes and sheltered by surrounding mountains that give it a mild, almost Mediterranean feel.
Its flower‑lined lakeside promenade, grand Belle Époque hotels and proximity to Château de Chillon make it a stop with a strong cultural and musical pedigree.
Vevey
Just along the lake from Montreux, Vevey has a more intimate small‑town atmosphere, with a handsome old town, lakeside quays and views across to the French Alps.
It is known for its links to Charlie Chaplin and for being at the heart of the Lavaux and Chablais wine‑growing region, where terraced vineyards tumble down toward the water. Look for the giant fork!
