Tuna Alley

Tuna Alley is a famous reef and channel dive on the western side of Bimini, named for the migrating tuna that historically passed through the area. The site features a coral-lined corridor between sand patches and ridges in 15 to 30 meters of water, with a mix of dense hard-coral mounds, gorgonians, and large barrel sponges. Currents can be moderate, providing a comfortable drift experience that brings pelagic action in close. Caribbean reef sharks, large jacks, and the occasional schooling barracuda patrol the corridor, while resident grouper, snapper, and triggerfish populate the reef structure. The site is part of the Bimini Marine Reserve and benefits from protections that have kept fish populations strong. Visibility is typically very good thanks to Bimini's proximity to the Gulf Stream, and the action-oriented nature of the dive makes it a long-standing favorite for intermediate divers comfortable with currents and pelagic encounters. Operators such as Neal Watson's Bimini Scuba Center include Tuna Alley as a staple in their rotation, often paired with shark-feed sites or with the more colorful patch reefs shoreward. Photography rewards wide-angle setups for capturing the corridor's depth and the schooling fish moving through it.
