Great Isaac Cay is a small Bahamian island located about 20 miles NNE of the Bimini Islands. It is accessible only by boat. And it is so small that it’s not visible on google map or google earth. The most prominent feature of the island is its lighthouse, which was erected in 1859.
In the late 19th century local lore tells of a ship wreck on the island with one survivor, an infant. The child’s distraught mother, known as the Grey Lady, is said to haunt the island to this very day, wailing in sorrow during the full moon.
On August 4, 1969, the station was discovered to have been abandoned by its two keepers, who were never found. The keepers’ house, cistern, and assorted buildings are crumbling into ruins. The Lighthouse looks abandoned but is actually still in use, fully automated.
It is also claimed to be haunted!
