Prepare for an engineering marvel that feels more like a roller coaster than a traditional railway as you reach the village of Brusio.
Because the Bernina Red operates without a rack-and-pinion system, it relies on ingenious loops to gain and lose altitude. The Brusio Spiral Viaduct is the crown jewel of this design, a 360-degree open-air stone corkscrew that allows the train to descend into the valley in a tight, elegant circle.
As a passenger on the regional red train, you have the unique advantage of being able to drop the windows and lean out to capture the perfect photograph of the engine passing directly beneath your own carriage. It is a moment of pure mechanical grace set against a backdrop of Italian-style vineyards.
Feel the atmosphere thin and the landscape transform into a lunar wilderness as you arrive at the highest station on the line, Ospizio Bernina.
Standing at 2,253 metres above sea level, this stop sits on the shores of Lago Bianco, a striking milky-white reservoir fed by glacial silt. This is the "Roof of the Railway," where the tracks skirt the continental divide; to the north, waters flow toward the Danube and the Black Sea, while to the south, they rush toward the Po and the Adriatic.
Surrounded by the towering Piz Bernina and the massive Cambrena Glacier, the view here is one of raw, high-alpine power, offering a stark contrast to the lush green forests you traversed just an hour earlier.
For a truly immersive encounter with the ice, keep your eyes peeled for the Morteratsch Glacier, the largest glacier in the Bernina Range.
As the red train winds its way through the Morteratsch Valley, the massive tongue of the glacier comes into full view, framed by the jagged peaks of the Bernina Massif. Unlike many other rail lines that view glaciers from a great distance, the Bernina Red brings you close enough to see the deep blue crevasses and the ancient moraines left behind by the retreating ice.
The Morteratsch station is a "request stop," meaning you can signal the driver, step off onto the gravel platform, and take a short walk to the very edge of the glacier's path—an experience that highlights the raw, changing nature of the Swiss wilderness.
