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. The Sierra de Cayey "extension" ends in a fork with two lower ranges: Sierra Guardarraya and Cuchillas de Panduras which run eastward to Yabucoa and Patillas respectively.
Another Cordillera Central eastern branch, Sierra de Luquillo, runs northeastwardly from Gurabo to Fajardo and includes several high peaks, including Toro Hill, at 3,524 ft (1,074 m), El Yunque at 3,494 ft (1,065 m) and El Pico Oeste at 3,446 ft (1,056 m).
