It is easy to understand why the Indians viewed this land as sacred. Puerto Rico offers astonishing variety. Lying 1,000 miles southeast of Miami, between the Atlantic Ocean and the Caribbean Sea, Puerto Rico is the eastern most and smallest of the Greater Antilles islands.
Numerous rivers flow down from the mountains to distinct coastal plains.
Towards the northwest, haystack hills, caves and sink-holes characterize the unusual terrain. In fact, one of the Western world's largest cave systems, the Camuy, stretches out below the surface and is of unending fascination to spelunkers, who still have not discovered all the cave's dimensions. In the southwest, mangroves have created a unique canal system. The island of Puerto Rico is almost rectangular in shape, and is the smallest and the most eastern island of the Greater Antilles. Its coasts measure approximately 580 km, and if the adjacent islands Vieques and Culebra are including the coast measures approximately to 700 km.
