In 2008, Unesco classified the Swiss Rhaetian Railway as a world heritage site because takes riders way up high in the Alps.

The narrow-gauge journey of about four hours from Saint Moritz in Switzerland is a favorite tourist attraction. The train chugs at a mile and a half high along the Bernina Pass into downtown Tirano, Italy. For schedules and ticket prices, go to www.myswissalps.com/berninaexpress/packages
