Topography

About 75% of Puerto Rico's land area consists of hills or mountains. The higher mountains in Puerto Rico are: Cerro Punta (4, 389 ft), Rosa (4,156 ft), and Guilarte (3,952 ft).  The Cordillera Central range, separating the northern coast from the semiarid south, has the island's highest peak, Cerro Punta. Puerto Rico has 50 waterways large enough to be classified as rivers, but none is navigable by large vessels. The longest river is the Rio de la Plata, extending 46 mi (74 km) from Cayey to Dorado, where it empties into the Atlantic.
