Andros
Bahamas · Atlantic Ocean
Andros is the largest island in the Bahamas and home to the third longest barrier reef in the world, stretching over 190 km along its eastern shore. It is legendary for its blue holes — both inland freshwater caves and ocean-connected shafts — and for reliable shark encounters along its deep-water channels.
