The 120-mile Florida Keys island chain is home to the continental United States' only living-coral barrier reef. This teeming backbone of marine life runs the length of the Keys about five miles offshore and offers Florida Keys scuba diving vacation memories that last a lifetime.
Our coral formations are famous for their abundance of fish, from impressive schools of blue-striped grunts to toothy green moray eels. The U.S. government established the Florida Keys National Marine Sanctuary to protect our marine habitat.
Preserving the reef is a top priority for a good reason. There is no more versatile marine destination in the world. We have coral-encrusted ship wrecks and intricate natural coral formations. We have shallow reefs for snorkelers, and a range of deeper reefs for experienced divers.
