There are, of course, faster ways to cross Switzerland. But none is guaranteed to be as beautiful as the ride on the Glacier Express. The train runs between St. Moritz and Zermatt, taking around eight hours for the 291-kilometre route. With an average speed of 40 kilometres per hour, this is not a record-breaking time, but that is not the point of the world's slowest express train. On their day's journey, the wagons rattle through three cantons, cross seven valleys, roll over 291 bridges and through 91 tunnels. And in front of the panorama windows, a grandiose nature film is playing the whole time, with spectacular views that simply make you happy. The red and white train passes deep blue mountain lakes, winds through alpine high valleys, crosses passes and gorges and offers new, magnificent images with every kilometre of track.

If you have some time, you can also cover the route in stages with overnight stays. The first recommended stop is Chur, Switzerland's oldest town with a settlement history of over 5,000 years. The Bishop's Court with its 800-year-old cathedral towers over the fantastically preserved, car-free old town. It is one of the most important cultural monuments in Switzerland. In Tschiertschen, just seven kilometres away at an altitude of 1350 metres, traditional wooden houses characterise the old village centre. 20 kilometres west of Chur, a unique landscape awaits visitors in Flims - the Rhine Gorge, also known as the 'Swiss Grand Canyon'. Hiking trails lead along the Rhine past rugged cliffs, forests and wide meadows. Sports enthusiasts can enjoy thrilling rafting tours or bike excursions, and wonderful selfies can be taken from the viewing platforms with the gorge in the back.
