Cerro de Punta or Cerro Punta is the highest peak in Puerto Rico, rising to 1,338 meters (4,390 ft) above sea level. The mountain is part of the Cordillera Central and is located on the town boundary between the municipalities of Ponce and Jayuya in the central region of the main island of Puerto Rico.
The Cordillera Central is the only mountain range in the main island of Puerto Rico, consisting of three subranges: the western-central Cordillera Central, the southeastern Sierra de Cayey, and the northeastern Sierra de Luquillo. Bordered by the Northern Karst Belt to the northwest and costal plains to the north and south, the numerous ridges and foothills of the three subranges combined extend throughout the island. Concentrated in the western to central region of the island, the eponymous main subrange of Cordillera Central originates in the municipality of Mayagüez and merges with the Sierra de Cayey subrange on the town boundary between the municipalities of Barranquitas and Aibonito. At 1,338 meters on the town line between Ponce and Jayuya, Cerro de Punta is the summit of the Cordillera Central and the highest point in Puerto Rico.
