Top Snorkeling Spots In Florida Keys

by | Jul 29, 2022

Snorkeling cruises off the coast of the Florida Keys are an absolute necessity for anyone who takes pleasure in the sea and the natural world. These trips cover a distance of around 120 miles and include more than 1700 islands. The coral reefs in the Florida Keys are home to an abundance of marine life, including tropical fish, sea turtles, rays, and even sharks. It is a unique and wonderful experience to observe them in the natural setting in which they live.

The Keys are divided into 5 regions: Key Largo, Islamorada, Marathon, Big Pine, the Lower Keys, and Key West. Key Largo is referred to as the Dive Capital of the World and is home to the amazing John Pennekamp Coral Reef State Park, and Christ of the Abyss. The Florida reef system is the only living coral barrier reef in the continental United States.

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 that 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 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 it can also be found in the waters of the Florida Keys. If you keep your distance and don’t mess with them they will rarely mess with you.

Other Sea Life

While snorkeling you’ll see many other forms of vibrant sea life, many not as dangerous as the marine animals listed above. Some examples of what you might see are:

Sea turtles

Star and Brain corals

Tropical fish

Sea urchins




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.

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.

When is the Best Time to Snorkel in the Florida Keys

The best time for snorkeling in Florida depends on what you are looking for. 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- perfect for a visit to the tropical coral reefs.

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!

How to Book a Florida Keys Snorkel Tour

Research is key here and reading the reviews of the various options for a snorkel tour. If you are taking young children you’ll want to choose a tour that caters to families and doesn’t take you way out. 

If you are an adventurous sort, you may want to look for snorkel companies that head out to Sombrero Reef or Alligator Reef. 

Call the companies that you’ve targeted and get more information on their tours. Once you arrive in the Keys, stop in, and visit them.

  1. Florida is an excellent destination for me. My family and I love to go to beaches when we have birthdays. So we planned to vacation on my birthday and tried snorkeling and scuba diving this time. I am scared, yet I hope I can try to experience it.

    • I can’t wait to hear how your vacation went!!

  2. Yes I snorkeled Look Key twice, about 10 years apart. Bahia Honda State Park runs a snorkel boat to Look Key twice a day. Great experience, and the 2nd trip was my first experience swimming with a shark nearby.

    • Cool!
