|Glacier Express Train, St Moritz to Zermatt|
|Connecting St Moritz and Zermatt, this may be the world's most spectacular train ride.|
For a whole day's worth of breathtaking alpine scenery, nothing beats the Glacier Express, the excursion train that travels for 7-1/2 hours from Zermatt in southwestern Switzerland via Davos to St Moritz in the southeast (and vice-versa).
The Glacier Express makes one run in each direction daily in winter, twice daily in summer (when longer hours of daylight make it worthwhile to have a second train).
The train's route is an engineering marvel, with 91 viaducts, 291 bridges, and a 13-km (8-mile)-long tunnel drilled right through Furka Mountain.
Better take it while we still have glaciers....
