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.
