Cordillera Central (English: Central Mountains range) is the main mountain range in Puerto Rico. The range crosses the island from west to east and divides the island into northern and southern coastal plains. Cordillera Central runs eastward from Maricao in the west to Aibonito in the central eastern Puerto Rico region and on to the outskirts of the Sierra de Cayey. Sierra de Cayey is an extension of Cordillera Central that begins in the town of Cayey and runs eastwardly to Humacao.
