Tropical Fish Florida Keys

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.

Most dive sites are equipped with convenient mooring buoys to save the reef from anchors and make it easy for boaters to tie off. Most sites are a short boat ride from our islands, where dozens of highly professional dive operators are ready to cater to you.

Once you visit the Keys, you'll see why some of the some of the most renowned dive photographers and writers in the world make this their home base.

Tips for Your Next Florida Keys Scuba or Snorkeling Vacation

Tips for your dive or snorkel trip dedicated to the protection of coral reefs

  • Ask about the weather conditions. Poor visibility, strong winds & surge from waves reduce safe interaction at the reef.
  • Remember that even the lightest touch with hands, fins or other dive and snorkel equipment can damage sensitive coral polyps, the small living animals that make up the hard and soft corals at the reef.
  • Snorkelers should wear buoyancy control or snorkel vests to allow gear adjustments without standing on the coral.
  • Avoid contact with the ocean bottom; properly weighted divers should practice proper buoyancy control. Sandy areas that appear barren may support new growth if left undisturbed.
  • Please don't feed the fish; it destroys their natural feeding habits, and avoids any potential injury to you or the marine life.
  • Remember, it's illegal to harvest coral in Florida.
  • If you dive or snorkel on your own, be aware of reef mooring buoys to use instead of anchoring a boat; many dive and snorkel sites are located within the Florida Keys National Marine Sanctuary, and anchoring in these Sanctuary Preservation Areas (SPA) is prohibited.
  • Whether freediving or on scuba, spearfishing enthusiasts (also referred to as "spearos") can find many spots for spearfishing opportunities, although there are regional zones that are protected from fishing within the Florida Keys National Marine Sanctuary.
