Top 5 Things to Do in the Florida Keys: Extraordinary Experiences Beyond the Beaches

The south of the Sunshine State is famous for its turquoise waters, vibrant coral reefs and spectacular sunsets. But beyond its familiar tropical image lies a world of extraordinary stories, unexpected discoveries and countless things to do in the Florida Keys.

An Italian-inspired bronze statue stands beneath the sea near Key Largo. Key West once declared independence from the United States. And on a remote island west of the Keys, an enormous 19th-century fortress became the prison of a doctor connected with Abraham Lincoln’s assassination. These are just some of the discoveries that make the Florida Keys much more than a beautiful holiday destination.

Stretching from Key Largo to Key West, this remarkable island chain combines unusual history, fascinating characters, natural wonders and experiences you won’t find in many other parts of Florida. Here are five ways to discover a different side of the Florida Keys.

1. Discover Christ of the Abyss in America’s First Undersea Park

Imagine descending beneath the water near Key Largo and finding a nine-foot bronze statue standing on the ocean floor, its arms extended towards the surface. This is Christ of the Abyss, one of the most unusual underwater attractions in Florida.

The sculpture depicts Jesus Christ and is based on an original work created by Italian artist Guido Galletti in 1954. The original was placed beneath the Mediterranean Sea near Genoa, Italy. Several castings were subsequently produced, including the one installed in the Florida Keys.

The Florida statue was lowered into position on August 25, 1965, and formally dedicated the following year. Its installation was connected with the efforts of Italian diving enthusiast Egidio Cressi, the Underwater Society of America and Florida Senator Spessard Holland.

Its location is particularly appropriate. John Pennekamp Coral Reef State Park, established in 1963, was the first undersea park in the United States. It protects approximately 70 nautical square miles of coral reefs, seagrass beds and mangrove habitats.

Visitors can explore the park through snorkeling, scuba diving, kayaking and glass-bottom boat excursions. The statue itself is a destination for snorkelers and divers, rather than a regular stop on the glass-bottom boat tours. Even without getting into the water, the park provides an excellent introduction to the extraordinary marine environment surrounding the Keys.

Where to visit: John Pennekamp Coral Reef State Park, Key Largo, Mile Marker 102.5 on the Overseas Highway.

Visitor information: Check the official park website for current admission, tours and conditions.

2. Discover the Conch Republic: The Florida Keys’ Extraordinary Independence Story

In April 1982, Key West did something that sounds almost unbelievable. It declared independence from the United States. The story began when the US Border Patrol established a roadblock on US Highway 1 near Florida City, stopping and searching vehicles traveling between the mainland and the Florida Keys.

The resulting traffic delays caused considerable disruption. Local businesses feared that visitors would avoid the Keys, damaging an economy heavily dependent on tourism. After attempts to have the roadblock removed failed, Key West Mayor Dennis Wardlow announced that the Florida Keys would secede from the Union. On April 23, 1982, the Conch Republic was proclaimed.

What followed was an extraordinary piece of political theatre. A symbolic rebellion involved an attack on a Coast Guard vessel using water balloons, Cuban bread and conch fritters. The new republic promptly surrendered and demanded one billion dollars in foreign aid. Although the roadblock eventually disappeared, the Conch Republic identity survived.

Today, it has become an enduring part of Key West‘s independent-minded personality, complete with its own flag, humorous government titles and annual Independence celebrations around April 23. What makes the story particularly interesting is that it began with a genuine local dispute about the difficulties of living in a geographically isolated community.

The Conch Republic may be deliberately theatrical, but its origins reveal how important access and tourism are to the Florida Keys.

Where to visit: Explore historic Old Town Key West, particularly the waterfront around Mallory Square.

Visitor information: The annual Conch Republic Independence Celebration takes place around April 23, with individual events varying each year.

3. Visit the Remote Fortress Where Lincoln’s Assassin’s Doctor Was Imprisoned

Approximately 70 miles west of Key West, surrounded by the waters of the Gulf of America, stands one of America’s most extraordinary historic fortifications. Fort Jefferson occupies Garden Key within Dry Tortugas National Park. Its enormous brick walls and isolated location make it an unforgettable destination.

Construction began in 1846, when the United States wanted to protect important shipping routes through the Gulf of America. Thousands of workers contributed to the project, including enslaved labourers during its early construction. Despite decades of work, the fortress was never completed. Transporting materials to such a remote location, along with financial difficulties, disease and changing military technology, made the undertaking exceptionally challenging.

Its most famous historical connection came after the Civil War. Fort Jefferson became a federal military prison, and among its prisoners was Dr. Samuel Mudd, who treated John Wilkes Booth after Booth assassinated President Abraham Lincoln in 1865. Mudd was convicted of conspiracy in connection with the assassination and sentenced to imprisonment at Fort Jefferson.

His story took another remarkable turn in 1867, when yellow fever swept through the isolated fort. Mudd assisted with treating the sick during the epidemic, helping to establish the medical contribution that later became important in the campaign for his release. President Andrew Johnson pardoned him in 1869.

Today, visitors can explore the fortress, walk along its impressive brick walls and discover the history of the soldiers and prisoners who once lived there. The surrounding islands also offer exceptional opportunities for snorkeling, swimming and birdwatching.

Where to visit: Fort Jefferson, Dry Tortugas National Park.

Visitor information: The park is accessible only by authorized ferry or seaplane services from Key West. Reservations are essential, and the excursion requires a full day. Check the National Park Service website before traveling.

4. Meet the Sea Turtles Being Rescued at Marathon’s Turtle Hospital

Not every extraordinary Florida Keys experience involves unusual history or spectacular underwater scenery. In Marathon, visitors can discover an organization devoted to rescuing and rehabilitating injured sea turtles.

Established in 1986, the Turtle Hospital is a nonprofit rehabilitation facility treating turtles affected by boat strikes, fishing equipment, marine debris and disease. Some animals arrive with serious injuries requiring surgery and months of specialist care. Others need prolonged rehabilitation before they can safely return to the ocean. The hospital offers visitors an opportunity to see the practical side of marine conservation.

Educational guided tours introduce different sea turtle species, explain common injuries and demonstrate the veterinary work involved in rehabilitation. Visitors can also observe some of the turtles in their rehabilitation tanks.

Not every turtle can return to the wild. Some suffer permanent injuries or conditions that make independent survival impossible. Understanding this is an important part of the experience. For families and wildlife enthusiasts, the hospital provides a fascinating insight into the work involved in protecting the Florida Keys‘ marine environment.

Where to visit: The Turtle Hospital, Marathon.

Visitor information: Tours operate by reservation. Check the official website for current schedules, admission and accessibility information.

5. Discover the History Behind Mallory Square’s Famous Sunsets

Every evening, visitors gather at Mallory Square in Key West to watch the sun disappear over the Gulf of America. Street performers, musicians, artists and food vendors create a lively atmosphere around one of the most famous sunset celebrations in Florida.

But this waterfront has a much older story. In 1823, Commodore David Porter established an American naval base in Key West as part of efforts to suppress piracy in the Caribbean and surrounding waters. As Key West developed into an important maritime centre, another industry helped make the island prosperous: wrecking.

The dangerous reefs surrounding the Florida Keys presented a constant threat to passing ships. When vessels ran aground, local wreckers raced to rescue crews and recover valuable cargo. The recovered merchandise was brought to Key West, stored in waterfront warehouses and sold at auction. Wrecking became an important source of wealth for the island and helped establish its position as one of Florida’s most prosperous communities during the 19th century. 

Today, the waterfront has a very different personality. The modern Sunset Celebration developed during the late 1960s, bringing artists, performers and visitors together to enjoy the evening spectacle. Arrive before sunset to explore the waterfront, watch the performers and enjoy the views. It is a wonderful way to experience the atmosphere of historic Key West.

Where to visit: Mallory Square, historic downtown Key West.

Visitor information: The public Sunset Celebration takes place daily, with activities generally beginning about two hours before sunset. Admission is free, although food and purchases from vendors are extra.

Planning Your Florida Keys Adventure

The Overseas Highway connects the islands through a remarkable sequence of bridges and causeways, making the journey an attraction in its own right. Key Largo is the natural starting point for exploring John Pennekamp Coral Reef State Park. Islamorada offers fishing and boating, while Marathon provides access to the Turtle Hospital.

The Lower Keys offer quieter surroundings, while Key West combines maritime history, distinctive architecture and lively entertainment. Fort Jefferson requires a separate excursion from Key West, so allow an additional day if you want to explore the Dry Tortugas.

Winter and spring are popular visiting seasons, although summer offers warm water and opportunities for outdoor activities. Florida’s hurricane season runs from June through November, so check weather forecasts and travel arrangements when planning your trip.

Explore Things To Do in the Florida Keys Beyond the Beaches

The Florida Keys are much more than a collection of beautiful tropical islands. They are a place where an Italian-inspired sculpture stands beneath the sea, a community once declared independence from the United States and an enormous island fortress became the prison of a man connected with one of America’s most notorious historical events. They are also home to people working to protect endangered marine animals and a waterfront where centuries of maritime history meet a famous sunset tradition.

The next time you travel along the Overseas Highway, remember that there is much more to discover than the beautiful scenery. Sometimes the most extraordinary Florida stories are hiding in plain sight.
