About this sanctuary

Once you set foot in Florida Keys waters, you have entered Florida Keys National Marine Sanctuary. This marine sanctuary protects 4,539 square miles of waters surrounding the Florida Keys, from south of Miami westward to the Dry Tortugas (excluding the National Park). It is home to North America’s only living barrier coral reef (and the third largest in the world), one of the world’s largest contiguous seagrass habitats and extensive mangrove forests, more than 6,000 species of marine life, and over a thousand shipwrecks and other submerged maritime heritage and cultural resources. Florida Keys National Marine Sanctuary is an international destination for scuba diving, fishing, and boating.

In national marine sanctuaries, America’s marine heritage is appreciated by current and future generations.
