Flam Railway, Norway
Climb aboard a train on the Flam Line and watch dramatic views of Norway's countryside roll by as you travel up emerald green mountains. Keep an eye out for a rare 15th-century wooden church, the large Rjoandefossen waterfall and mountain farms with herds of wild goats. As you continue to ascend one of the world's steepest railways, you'll see incredible Norwegian vistas -- blue fjords and silver rivers thousands of feet below -- as a guide explains the history of the region over a loudspeaker (this service is available in several languages). The Flam Railway is a major Norwegian tourist attraction that hosts more than 500,000 passengers annually, and many who have taken the ride claim that it travels through the most beautiful scenery in the country.
