Florida Keys National Marine Sanctuary, located in the waters surrounding the Florida Keys in Florida, encompasses 4,539 square miles of diverse marine habitats, including North America's only coral barrier reef and the largest contiguous seagrass beds in the Northern Hemisphere. Established in 1990 and managed by NOAA in partnership with the state of Florida, the sanctuary protects over 6,000 species of marine life as well as significant cultural and historical resources such as shipwrecks. Its unique ecosystem, characterized by turquoise waters and vibrant biodiversity, makes it a premier destination for marine conservation and recreation. The sanctuary’s extensive experience in marine protection and research, supported by facilities in Key West and Key Largo, ensures the preservation of this fragile environment for future generations. The sanctuary offers a wide range of activities including world-class diving, snorkeling, fishing, boating, and wildlife viewing, attracting both residents and millions of annual visitors. The Florida Keys Eco-Discovery Center in Key West provides an immersive educational experience with interactive exhibits on coral reefs, mangroves, seagrass habitats, and maritime history, allowing visitors to explore the sanctuary’s wonders without entering the water. The sanctuary also engages the public through coral restoration programs and volunteer opportunities, fostering stewardship and awareness. With a strong emphasis on sustainable use and protection, the sanctuary balances recreational access with regulations designed to safeguard its natural and cultural resources.
