Great Harbour Cay is the major island in the north Berry Islands. The Islands are a stirrup shaped chain of thirty large cays and numerous small cays of about thirty-two miles in length. The islands are located to the south of Great Abaco and about forty miles north-northwest of Nassau.
The natural beauty of the Berry Islands is extraordinary. It has seven miles (11 km) of ocean front beaches that include isolated enclaves, caverns, and open expanses. Haines Cay has 3.5 miles (5.6 km) of beaches. At the point of closest approach of Haines, Great Harbour, and Hawksnest, there are 10–15 acres (40,000–61,000 m2) of white sand shallows with starfish, sand dollars and other shallow water creatures.
The island was substantially damaged by Hurricane Andrew in 1992, but has fully recovered since. The Hurricane made landfall twice while moving through the Bahamas, crossing Eleuthera with 160 mph (260 km/h) winds and passing through the Berry Islands with sustained winds of 150 mph (240 km/h).
