About Banana Patch Reef
Banana Patch Reef is the southern end of the Grecian Rocks reef system in Key Largo, where a long sloping ledge curves out from a shallow coral top into sandier water. It is a relaxed boat-run reef that is best on calm days, with bright coral color, patchwork habitat, and Thunderball film remnants that add a little history to the dive.
