7. Ferrocarril Chihuahua al Pacifico (Copper Canyon Railway), Mexico
Mexico’s Copper Canyon is four times larger than the Grand Canyon, and one of the best ways to take in all in is by train. Construction on this railway line began in 1898, a pretty ambitious project considering the rugged terrain and limited technology of the day. The Copper Canyon Railway chugs along the 400 miles (655km) between Los Mochis and Chihuahua, passing over 36 bridges and through 87 tunnels. The sheer cliff walls, cascading waterfalls, desert plains and cactus-strewn mountain scenery will make you say ay, Chihuahua!
