Bimini is surrounded by shallow reefs near shore - but the depth then increases to 80 to 100 feet before dropping into the abyss of the Gulf Stream. To the west, the Gulf Stream current flows north through the deep water between Miami and Bimini, where the ocean is over 6,000 feet deep. The Gulf Stream brings hundreds of marine animals near to the shores of Bimini.
Bimini is only 50 miles east of Miami Beach, Florida.
Bimini has three main islands: North Bimini, East Bimini and South Bimini. These coral islands are small, only 7 miles long and only 200 yards wide at their narrowest. Perched at the west end of the Bahamas Bank, Bimini is surrounded by shallow water (only 20 to 30 feet deep) to the north, south, and east.
