Beginning in the mountaintop town of Creel, the Chihuahua Pacifico Express - or El Chepe for short - winds its way through the Tarahumara Mountains, home to the reclusive Raramuri people. Divisadero, Mexico's most panoramic station, offers the first glimpse of Copper Canyon. Created by six separate yet conjoined gorges, it is four times the size of the Grand Canyon. The train continues on to the Urique Canyon, which at 6,200ft deep it is the deepest in North America. The final leg crosses the state of Sinaloa, Mexico's breadbasket, before reaching Los Mochis and the gateway to the Pacific Ocean.
