The train journey from Milan to Zurich is considered one of the most stunning rail routes in Europe, especially if you opt for the scenic detour. The standard high-speed route via the Gotthard Base Tunnel is the fastest (around 3 hours and 15 minutes) but spends a large portion of time in darkness inside the world's longest railway tunnel. For true scenery, you should take the Gotthard Panorama Express or a regional train on the "mountain route" that goes over the Alps rather than through them, offering views of the iconic Wassen Church and dramatic loops. Alternatively, for the ultimate bucket-list experience, travelers take a train from Milan to Tirano to board the Bernina Express. This UNESCO World Heritage route climbs to the Ospizio Bernina at 2,253 meters, passing the Morteratsch Glacier and crossing the famous circular viaduct at Brusio before descending into the Swiss heartland. Even on the direct route, the stretch passing through the Italian Lake District and the approach to Lake Zurich provides breathtaking vistas of crystal-clear water and snow-capped peaks.
