Is It Safe To Go Snorkeling In The Florida Keys?

Any water sport comes with some level of danger, and snorkeling is no different. The coral reefs are living, and house dangerous sea creatures, as well as other dangers can be in that environment. But overall, snorkeling while in the Florida Keys is fairly safe. Here are some dangers to be aware of when Florida Keys reef snorkeling.

Fire Coral 

Fire coral is common on and around the reefs and is sharp enough to cause small cuts. They are yellow or brown in color and attach themselves to rocks, seaweed, and other coral.

When you brush up against fire coral it can cause mild stinging and can develop into a rash. You can find suggested treatment here, if you happen to come in contact with fire coral during your snorkeling adventure.


Jellyfish can sting – when I was growing up we often went waterskiing. And I usually fell off – and usually always got a jellyfish sting or three. But there are two varieties of jellyfish that are dangerous – the box jellyfish and the Portuguese man-of-war jellyfish.

Both the box jellyfish and the Portuguese man-of-war can be fatal to humans, however, if stung multiple times by a Portuguese man-of-war it can be fatal.

I love to snorkel, but I am truly petrified of sharks. When snorkeling Dry Rocks in John Pennekamp I came face to face with that fear and overcame it. There are lots of sharks in the Keys, but shark attacks are rare.

The most common sharks in the Keys are nurse sharks. They are docile, harmless sharks that spend time close to the sea floor. You're more than likely to spot them while snorkeling many feet above in the coral reefs.

Caribbean reef sharks are everywhere in the Keys, but they are relatively harmless. However, the bull shark is a very aggressive shark, and they can also be found in waters of the Florida Keys. If you keep your distance and don't mess with them they will rarely mess with you.

Snorkel & Dive with Professionals 

Unless you intimately know the waters where you'll be snorkeling and have snorkeled there many times, our suggestion is to always go with a professional snorkel company .

If you want to learn to dive on your vacation, try a dive resort like Amy Slate's Amoray Dive Resort, or for a more luxury stay,  Hawks Cay Resort on Duck Key is fabulous. For an immersive experience, Looe Key Reef Resort is a great choice and is one of the most affordable motels in the Florida Keys.

All of these resorts offer snorkeling trips as well, giving you double the experience if you want to learn to dive while you're snorkeling in the Keys.

Alligator Reef Lighthouse in Islamorada

The Alligator Reef Lighthouse is widely regarded as one of the most desirable spots in all of the Keys for scuba diving and snorkeling. The United States Ship Alligator went down in shallow water in 1825 when it was engaged in a mission to combat pirates off the coast of Islamorada.

The crew decided to blow up the ship, which resulted in it breaking in half and sinking to the bottom of the water. This was done to prevent the pirates from reclaiming the 86-foot-long vessel. This marked the birth of the massive coral reef that is now home to more than 500 different types of marine life.

Sombrero Reef in Marathon

In the vicinity of Marathon, Florida, Sombrero Reef is one of the most well-known spots for Florida Keys snorkeling and scuba diving, and it has been recognized as a Special Protected Area (SPA).The arch is a massive limestone structure that is covered with countless colorful stony and gorgonian coral and sea sponges.

Key Largo Dry Rocks in Key Largo

The “Christ of the Deep” monument is located in Key Largo Dry Rocks. It is a bronze figure that measures nine feet in height and lies in a sand channel on the offshore side of Key Largo Dry Rocks in water that is less than twenty-five feet deep.

Looe Key National Marine Sanctuary, Big Pine Key

Looe Key is a good SCUBA and snorkeling spot for visitors of all skill levels who are interested in visiting Florida Keys Parks. The key's rich history, as well as its distinctive form and changing depths, contribute to the key's appeal. The water clarity is almost universally superb, and the waves are often of a moderate intensity.

When is the Best Time to Snorkel in the Florida Keys

The best all-around month to visit the Florida Keys is May (prior to Memorial Day). The weather is warm, the waters are calm and clear, it is not as crowded, and the prices are reasonable. September is also a good time to visit the Florida Keys, but it is hurricane season, which is a bit of a risk.

Summer in the Keys means great snorkeling but it also means gobs of people and higher prices. The conditions, however, mirror May – calm, clear water but oppressively hot. However, jumping into the cool water of the Keys is a great getaway from the hot sun!
