One of the most fabulous places on the North American continent is Copper Canyon located in the northwestern part of Mexico. It is in fact, a group of six canyons that make up the breathtaking landscape. The canyons are carved by rivers that flow from the west side of the Sierra Madre Occidental mountain range and form the Rio Fuerte River, which flows into the Gulf of California. The Copper Canyon is one of the most commonly used sets for 20th-century western movies. One of the favorite ways to tour this canyon is the Ferrocarril Chihuahua al Pacífico railway line, better known as El Chepe, which is the last long passenger line in Mexico, and which connects the port of Los Mochis on the Gulf Coast and Chihuahua City.
