This train from Swiss Chur to Italian Tirano may be one of the greatest memories of your Swiss vacation. During a 4-hour trip, you'll pass 55 tunnels and almost 200 bridges. The highlight of the journey is the 65-meter-high Landwasser Viaduct. You can also see mountain lakes, glaciers, and gorgeous canyons.
The best season to take this train is spring for the combination of snow-capped mountains, spring flowers, and lush green valleys. Moreover, the trains go more frequently during May-October, so you can choose a better scheduled ride.
