Site description Great Isaac Cay is located about 18 nautical miles north-north-east of the Bimini Islands in the Northern Bahamas, and is only accessible by boat. The most prominent feature on the cay is the lighthouse which stands approximately 151 feet (46 metres) high. It was built in 1859, standing at the intersection of the NW Providence Channel, the Great Bahama Bank and the Straits of Florida. The lighthouse is still functioning although it has been abandoned since 1969 when the two keepers mysteriously vanished.

Protection status This site has conservation, historical and cultural heritage potential. From the point of view of both diversity of seabirds and for the protection of one of the nation’s largest Bridled Tern colonies there is a strong case for the establishment of a national park or other protected area encompassing Great Isaac Cay.
Access/Land-Owner requests Accessible only by boat.
