The Bernina Express is Switzerland’s UNESCO-listed panoramic train linking St. Moritz/Chur and Tirano across the high Bernina Pass. Expect floor-to-ceiling windows, close-up glacier scenery at Morteratsch and Ospizio Bernina, turquoise Lago Bianco, the dramatic terraces of Alp Grüm, and the photogenic Brusio spiral viaduct. It runs year-round—snow-globe winters and high-alpine summers—so it slots into ski breaks and warm-weather itineraries alike. For a refined day out, book First Class in the panorama cars, time lunch at Alp Grüm or in Tirano, and pair the ride with an Engadin spa evening back in St. Moritz. Seat reservations are required for Bernina Express panorama coaches (you still need a ticket or rail pass); regional trains on the same line deliver similar views with more flexibility. For standout vistas, sit on the right-hand side traveling St. Moritz/Chur → Tirano.
