The Cordillera is a massive mountain range situated in the northern central part of the Philippines. Several provinces bound it, namely Benguet, Abra, Kalinga, Apayao, Mountain, Ifugao, and a city located entirely within it, which is Baguio City. It links with the Sierra Madre through the Caraballo mountains in Nueva Vizcaya province. The whole range was formerly termed as Nueva Provincia, or New Province, during the Spanish times. Its inhabitants are presently Ilocanos, and the Igorot, a loosely-connected federation of tribes belonging to the mountains. Most of them speak English, due to the presence of a former American base in the mountain ranges, Camp John Hay.
