Coffins Patch is a shallow offshore patch reef in the Middle Keys where boat access, moorings, and protected coral habitat make it a classic snorkel and dive stop. The reef is shallow enough for relaxed exploration, but it still has enough structure and marine life to reward careful buoyancy and a measured pace. It rewards patience on calm days.
