Snorkeling On Sombrero Beach: What To Expect

sombrero beach

Sombrero Beach in the Florida Keys is a great holiday destination, especially if you love water sports such as swimming and snorkeling. Not only is the beach itself gorgeous, but it has a beautiful park area that includes volleyball courts, picnic places, restrooms, and even showers.

One of the things that makes the beach so special is that it’s a turtle-nesting beach. From April until October loggerhead turtles, among other types, visit the beach at night to lay their eggs. Although these nesting areas typically only take up 10% of the beach area, it’s still good to be aware of them because the city is determined to preserve the nesting population.

Sombrero Beach vs Sombrero Reef

Sombrero Beach is officially located in the city of Marathon, Florida. In addition to diving and other water-based sports, you can also go snorkeling in the area if you like. Of course, the most delightful snorkeling venues are a few miles away in an area known as “Sombrero Reef”. Although you can snorkel on Sombrero Beach, the water tends to be a bit murky most of the time. For this reason, most people choose Sombrero Reef instead. Another reason why snorkeling isn’t the best on this beach is that the water tends to be a little too shallow.

In other words, if possible, try to visit Sombrero Reef for the ultimate snorkel experience.

The Large Area

The reef is a mere 4 miles from Sombrero Beach, and there are many different companies that sponsor all types of snorkeling tours. Most of them provide daily trips to both Sombrero Reef and nearby Pirate’s Cove, which is located on the Florida Bay. Sombrero Reef is the third largest coral reef in the world and therefore a very popular tourist attraction.

Possible Winds

There is one thing you need to be aware of when you wish to snorkel on Sombrero Reef: The area often experiences strong winds. In fact, most of the companies that sponsor these tours recommend that you call them in the morning prior to your excursion. Depending on when your excursion is scheduled, they’ll be able to tell you whether or not your trip will be taking place on that specific day.

Biologically Diverse Ecosystem

Not only is this third-largest barrier reef in the world an amazing place to visit, but it’s a full 30 acres in size. It offers waters from 2 to 30 feet deep to enjoy. This water has thousands of tropical fish in it to delight snorkelers. Furthermore, the coral reefs are some of the most biologically diverse ecosystems on the planet. When it comes to the available species, they’re second only to the tropical rain forests.


Of all the sites to see in the Florida Keys, Sombrero Reef is certainly one of the most amazing. There’s even a lighthouse that still helps mariners navigate the Keys today. It was built before the Civil War, so if you’d like to tour a piece of history in between your snorkeling adventures while you’re there, you have some great options.

Marine Life

Of course, most people come to Sombrero Reef for the underwater activities. Not only will you find tons of tropical fish species, but also underwater plant life, lobsters, and even seahorses for your viewing pleasure. It’s shallow enough to accommodate snorkelers without being too shallow, which is why these companies don’t usually allow scuba divers on their tours.

What else can you expect to see on one of these snorkeling expeditions? More than you think! In fact, the underwater plants and animals are usually more than most people bargained for. A handful of the many things you can enjoy while snorkeling on Sombrero Reef include:

  • Green turtles
  • Hogfish
  • Moray eels
  • Nurse sharks
  • Parrot fish
  • Spiny lobsters
  • Sponges and coral

Most of the time you’ll even be able to see an observant barracuda standing at the base of the lighthouse. It’ll look like it’s not interested in you at all, but the truth is that you will be interested in it! Snorkeling on Sombrero Reef truly offers something for everyone, so the sooner you visit the area, the sooner you’ll be able to enjoy this truly awesome experience.
