Bimini Barge is a deep wreck and artificial reef on the edge of the drop-off off Bimini, dived for its open steel structure, blue-water setting and frequent pelagic traffic. Divers usually work around the barge exterior first, then inspect the superstructure and its tighter passageways where sponge, coral and fire coral have taken hold. Planning matters here: it is boat-only, starts deep, and often comes with medium to strong current that makes it a better fit for advanced divers.
