Beaches in Marathon Florida

Ahh. The Florida Keys. Heaven on Earth. Palm trees. Blue-green water. White beaches.

If you have not visited the Florida Keys yet, start planning. It’s amazing. Every island in the Florida Keys has amazing beaches, but I love the beaches in Marathon Florida.

Once you leave Miami, you will literally find the stress leave your body as soon as you enter the top of the Keys. From Key Largo following the Overseas Highway to Key West, the views are out of this world.

You will drive over several bridges including the 3-mile bridge and 7-mile bridge. I was so focused on looking at the water, I did not notice how long the bridges were. All I could see were the views!

The top key, Key Largo, is where the magic begins. But you will not want to stop there. The Florida Keys actually includes over 800 islands.

There are 882 charted Key islands, 30 of which are inhabited. The 204 kilometer (close to 127 miles) Overseas Highway connects the main islands from Key Largo to Key West.

The largest island is Key Largo which is roughly an hour drive from Miami International Airport. Key West is only 113 miles from Key Largo but be sure to enjoy every key as you make your way to the southernmost point in the USA.

It isn’t easy writing about only one Florida Key. I love all the islands. But this article is about the best beaches in Marathon Florida.

What is there to do in Marathon?

There are so many fun things to do on this island. I always have a tough time leaving because I haven’t done everything I wanted to!

My favorite things to do? They are:

  • Dolphin Research Center. I just can’t get enough of the dolphins!
  • Turtle Hospital. The Turtle Hospital (Hidden Harbor Marine Environmental Project, Inc.) is a sea turtle rescue and rehabilitation center. They offer guided tours and the chance to meet current turtles in house.
  • Sombrero Beach (which we will dig into below) as well as Sombrero Reef. This reef is located on the outer banks offshore of Vaca Key, and best known for the large fingers of coral. Absolutely breathtaking to snorkel over.
  • Curry Hammock State Park. This beautiful state park is known for its seclusion. Undeveloped parcel of pristine sanctuary located between Key Largo and Big Pine Key.
  • San Pablo Catholic Church. This church does offer a regular mass schedule, but it’s the gardens behind the church you must visit. Located at mile marker 53.5
  • Florida Keys Aquarium Encounters. This aquarium offers interaction with many marine animals including tropical fish, rays and even sharks!
  • Seven Mile Bridge. You will have no choice but to see this bridge as you drive over it. Be sure to also check out the old seven-mile bridge.
  • Crane Point Hammock, home to Crane Point Museum, Nature Center and Historic Site. Finally, be sure to save time to visit Crane Point Hammock. Perfect for nature lovers as they explore the tree canopies, boardwalks and wildlife along the trails. Bird centers, gift shop and even a fish pedicure all await your visit.

Best Beaches in Marathon Florida

There are some amazing beaches in the Florida Keys. Marathon has some of the best beaches making this city a great place for families, couples, girls trips and more.

Sombrero Beach. First on the list is Sombrero Beach. Sombrero Beach is located near mile marker 50 roughly a mile off US 1. (You’ll get used to the Keys speak in mile markers.)

Marathon Beaches Sombrero Beach

Sombrero Beach with its beautiful sand and shallow waters is a wonderful beach for beach lovers of all ages. This beach offers covered picnic pavilions and picnic tables, restroom facilities, and outdoor showers.

There are picnic tables conveniently located near the playground as well. Volleyball anyone? You will find sand volleyball courts at this beach. Look for Sombrero Beach Road located off US 1. This is a free beach.

Coco Plum Beach. I’m going to be honest. Coco Plum Beach can be hit or miss. I’ve visited this beach when it was covered in seaweed one day, and it was completely clear of any debris on the next day.

One of the things Coco Plum Beach is known for however, are the sea turtles and turtle tracks. Plenty of parking and toilets are available. This beach is located on Coco Plum Drive.

Calusa Beach located in Bahia Honda State Park. (Caloosa Beach is located on Islamorada.) In my opinion, this is probably one of the best beaches in the Keys and a great place to spend the day.

Crystal clear water and white sand awaits you in one of Florida’s prettiest state parks. From the beach, you can also see the Old Bahia Honda Bridge.

Bahia Honda Railroad Bridge

There is a fee to enter all Florida State Parks, but here it is only $8 per vehicle, up to 8 people in the vehicle. Shallow water and mild currents makes Bahia Honda State Park one of the best for swimming.

Loggerhead Beach located in Bahia Honda State Park. This is my top beach pick for snorkeling!

Tip: Bring your own snorkel gear. Equipment is expensive to rent in the Florida Keys. Plenty of parking, clean restrooms and showers makes this a top spot for nature lovers and marine life.

Sandspur Beach. The final beach in Bahia Honda State Park I must mention is Sandspur Beach.

Marathon Florida Reef Snorkeling

Sandspur Beach has been described by many as the prettiest beach in the world. Unfortunately Hurricane Irma did a bit of damage in 2019, but the beach is open for you to enjoy.

You will find a concession stand that offers a nice gift shop, snack bar, kayak rentals and daily snorkeling tours to the fabulous Looe Key National Marine Sanctuary. This beach is a definitely a must-visit.

Curry Hammock State Park. This Florida State Park is located on both sides of US 1 at mile marker 56.2.

One of the nicest beaches on the Atlantic Ocean side of the island. A sanctuary for wildlife including peregrine falcons that return each fall.

Smathers Beach. Before you leave the keys, take a drive south to Smathers Beach. This beach is also known as Smathers & Higgs Beach is one of the best in the keys. It is located in Key West.
