Causeway Islands (Naos, Perico, Flamenco)
Panamá
The Causeway Islands, known locally as Islas Calzada de Amador, consist of four small islands-Naos, Culebra, Perico, and Flamenco-situated at the Pacific entrance to the Panama Canal. These islands are connected to the mainland by a causeway built from rock excavated during the canal's construction, which also serves as a breakwater. A four-lane road and a bicycle/jogging path run along the causeway, making the islands accessible and popular for recreation. Naos Island hosts a research laboratory operated by the Smithsonian Tropical Research Institute, emphasizing the area's ecological significance. Historically, during World War II, the islands were fortified to protect the canal; although these defenses were never used, remnants like gun emplacements remain visible. The islands have seen significant development since Panama regained control from the Canal Zone, featuring port facilities, marinas, shopping areas, and restaurants. Despite this, much of the islands' interior remains covered by isolated maritime jungle, though ongoing development poses environmental threats. The Causeway Islands offer a unique blend of natural beauty, historical intrigue, and modern amenities, making them a notable destination near Panama City.

History
The Causeway Islands were formed and connected by a causeway constructed using rock excavated during the Panama Canal's construction in the early 20th century.
During World War II, the islands were fortified to protect the canal, although these fortifications were never engaged in combat and were later dismantled.
After the Canal Zone reverted to Panamanian control, the islands underwent significant development, transforming from strategic military sites to hubs for tourism, research, and recreation.
Manuel Noriega once had a private residence on one of the islands, which was destroyed during his ouster in the late 20th century.
