Serranilla Bank

Serranilla Bank spans over 1,200 square kilometers underwater and features three small cays and two rocks rising above the water surface.

The reef first appeared on Spanish naval maps in 1510 and later became subject to territorial claims from multiple Caribbean nations.

Colombian naval personnel maintain a rotating garrison presence on Beacon Cay, operating essential navigation facilities for maritime traffic.

Access to Serranilla Bank requires specialized nautical equipment and navigation skills due to its remote location 350 kilometers northeast of Nicaragua.

The location marked the final recorded sighting of the Caribbean monk seal in 1952, before the species became extinct.
