Diving and Snorkeling

As home to the only living coral barrier reef in the continental United States, Florida Keys National Marine Sanctuary is an ideal destination for snorkeling and scuba diving. From shallow coral reefs to historical shipwrecks, there's something for every diver, from beginner to technical level.
Every year more than 700,000 divers and snorkelers take to the water to discover the wonder and beauty of coral reefs in Florida Keys National Marine Sanctuary. This much activity can take a toll on the environment, but the dive and snorkel communities are among the most environmentally-conscious in the world, proactive in their belief that to whom much is given, much is required.
