Copper Canyon is really a set of at least seven major canyons in northwest Mexico. There is a famous train route that leads from the coast at Los Mochis, up into and above the canyons, ending in the city of Chihuahua. I took the train from Los Mochis to the town of Creel, where I got off and did all my travels from.
