Causeway Islands

The Causeway Islands (Spanish: Islas Calzada de Amador) are four small islands by the Pacific entrance to the Panama Canal. They are linked to the mainland via a causeway, made from rock extracted during the excavations from the Panama Canal. In part the causeway was meant to serve as a breakwater for the entrance. A four-lane road runs along the causeway to each island, and there is a bicycle/jogging path as well. The islands are as follows: Naos - home to a research lab run by the Smithsonian Tropical Research Institute (STRI).
