The Chihuahua al Pacífico Railroa, known as ChP or Chepe, is a major rail line in northwest Mexico, linking the city of Chihuahua, Chihuahua, to the town of Los Mochis, Sinaloa, near the Pacific coast. It runs 650 km (400 miles), traversing the Copper Canyon, a beautiful and rugged series of canyons that have led some to call this the most scenic railroad trip on the continent. It is both an important transportation system for locals and a draw for tourists.
