Dry Tortugas National Park: Florida’s Remote Island Fortress

Pirate-era shipwrecks. Spectacular coral reefs. A massive Civil War fort. These are just a few of the things that call a small cluster of tropical islands home. This is Dry Tortugas National Park, one of the most unique national parks in the United States. It is only reached by boat or seaplane. It is definitely worth the trip.

The park is located 70 miles west of Key West, Florida. It sits in the middle of the Gulf of Mexico. Seven small islands make up the park. The largest island, Garden Key, holds the massive Fort Jefferson. The surrounding waters contain shipwrecks, coral reefs, and abundant marine life.

Getting There: Key West First

The journey to Dry Tortugas starts in Key West, Florida. Key West is the southernmost place in the continental United States. It is a laid-back island city surrounded by turquoise blue waters. The weather is warm year round. The atmosphere is relaxed.

Visitors can fly directly into Key West. But the drive down from Miami or Fort Lauderdale is well worth it. Each key or island along the way offers something different. The views of the ocean from the Seven Mile Bridge are absolutely incredible.

For anyone planning to visit Dry Tortugas, booking a few nights in Key West is highly recommended. The city offers unique bars, restaurants, shops, and a famous sunset celebration.

Getting to the Park: Ferry or Seaplane

Dry Tortugas National Park is reached by either ferry or seaplane. The distance is 70 miles over open ocean. Neither option is cheap. Both have advantages.

The ferry is less expensive than the seaplane. It takes about two and a half hours each way. The ferry ticket includes meals, guided tours, and free snorkeling equipment. The boat plays almost exclusively Jimmy Buffett music. The ride can be long, so bringing a book or something to keep occupied is wise. There is no cell service once the boat leaves the dock.

The seaplane is more expensive but much faster. It gets visitors to the park in less than an hour. The aerial views of the park from the plane are amazing. The islands, the fort, and the surrounding waters look completely different from above.

Whichever option is chosen, arriving early is essential. Check-in for the ferry is at 7:00 AM sharp.

Fort Jefferson: The Center of the Park

Fort Jefferson dominates Garden Key. The seaplanes land here. The ferry docks here. The fort is the center of the park, despite occupying only a fraction of the total land area.

Construction on the fort began in 1846. The purpose was to protect American vessels from piracy and protect other U.S. interests in the Gulf of Mexico. The fort was never fully completed. Advances in weaponry made its massive walls less effective. Instead of a military installation, it was used as a prison for Union deserters during the Civil War.

The most famous inmate was Dr. Samuel Mudd. He was convicted of treating Abraham Lincoln’s assassin, John Wilkes Booth. Despite receiving a life sentence, Mudd was pardoned after four years. His medical skills during an outbreak of yellow fever within the fort earned him his freedom.

Exploring the Fort

Once the ferry docks and visitors disembark, there are many options. Heading straight to the beach is one choice. There are actually two white sand beaches on Garden Key.

Exploring the fort is another option. Visitors are free to go through most of it. Each turn reveals something new. The symmetry of the archways is striking. Walking the moat wall provides different perspectives. Dr. Mudd’s cell is marked for those interested in history. The top of the fort offers 360-degree views of the entire park.

It is easy to lose track of time here. The fort is massive. The history is deep. The views are spectacular.

Why the Name Dry Tortugas?

The name Dry Tortugas has an interesting origin. “Dry” refers to the lack of fresh water. There is no fresh water on any of the islands. Early residents had to rely entirely on collecting rainwater. “Tortugas” is Spanish for turtles. When Ponce de Leon came through the area in 1513, he named the islands “Las Tortugas” for the abundance of sea turtles.

Dry Tortugas. No fresh water. Many turtles. The name stuck for over 500 years.

Loggerhead Key: The Other Island

Garden Key is not the only island in the park. Loggerhead Key is visible from the fort. It has a massive lighthouse, a few trails, an underwater shipwreck that can be explored, one of the best reefs in the park, and is a popular nesting ground for sea turtles.

Loggerhead Key is open to visitors. But it does not see many people. Getting there requires a private boat or paddling over in a kayak or canoe. The open water can be dangerously choppy during winter months.

The ferry allows visitors to bring a kayak or small canoe for an extra fee. For day visitors, heading to Loggerhead Key is not recommended. The distance is three miles each way over open water. It takes longer than expected. Time in the park is limited for day trippers.

Camping: The Best Way to Experience the Park

The best way to get more time in the park is by camping. There is a two-night minimum. The best part is that once the ferry leaves, campers have the park almost entirely to themselves.

Campers are free to wander the fort until sundown. They can kayak, snorkel, hang out at the beach, and get an amazing view of the crystal clear night sky. The stars here are unlike anything visible from the mainland. Light pollution is nonexistent.

Camping at Dry Tortugas requires planning. All supplies must be brought in. There is no fresh water, no food, and no services. Everything needed must fit on the ferry. But for those who prepare properly, the reward is an unforgettable night in one of America’s most remote national parks.

Snorkeling and Marine Life

The waters around Dry Tortugas are spectacular. Coral reefs surround the islands. The visibility is often excellent. Snorkelers can see colorful fish, sea turtles, and even shipwrecks.

The ferry includes free snorkeling equipment. Visitors can snorkel right off the beach on Garden Key. For more adventurous snorkelers, the reefs around Loggerhead Key are even better. Getting there requires a kayak or private boat.

The marine life is abundant. Sea turtles are common. Tropical fish in every color of the rainbow swim among the corals. The park protects one of the healthiest reef systems in the Florida Keys.

History Beneath the Waves

The waters around Dry Tortugas hold more than just coral and fish. Pirate-era shipwrecks rest on the ocean floor. Ships carrying treasure, supplies, and people sank here over centuries. Some wrecks have been explored. Others remain undiscovered.

The most accessible wreck is near Loggerhead Key. It lies in shallow water and can be seen by snorkelers. The remains of the ship are encrusted with coral. Fish swim through the wreckage. It is a glimpse into a dangerous past when these waters were traveled by sailing ships and pirates.

What to Bring

For a day trip, the essentials are simple. Sunscreen is critical. The Florida sun is intense. A hat and sunglasses provide additional protection. Swimwear and a towel are necessary for snorkeling or beach time. A camera captures the fort and the views. Cash is useful for the ferry bar.

For camping, much more is needed. Water is the most important item. There is no fresh water on the islands. Campers must bring all the water they will need for the duration of their stay. Food must also be brought in. Cooking equipment, sleeping gear, and lighting are essential. Snorkeling gear can be brought or rented on the ferry.

Best Time to Visit

Winter and spring offer the best weather in Dry Tortugas. Temperatures are mild. Humidity is low. The water is still warm enough for swimming and snorkeling. Winter crowds are smaller than summer.

Summer is hot and humid. Afternoon thunderstorms are common. Hurricane season runs from June through November. However, summer also offers the calmest seas for kayaking to Loggerhead Key.

Fall is hurricane season. Trips during this time are risky. Storms can cancel ferry and seaplane trips with little notice.

Back in Key West: Sunset at Mallory Square

The ferry returns to Key West before sunset, depending on the time of year. Unless in a hurry, heading to Mallory Square is highly recommended. This is the home of the daily sunset celebration. A wide variety of street artists perform as the sun sets behind the Gulf of Mexico. Jugglers, musicians, magicians, and other performers entertain the crowd. It is a Key West tradition.

Duval Street is also worth visiting. It is the busiest and most touristy place in all of Key West. But for good reason. Unique bars, restaurants, and shops line the street. After the long ferry ride, Duval Street offers plenty of dining options. Trying key lime pie straight from the source is also recommended.

Adding the Everglades

Many visitors combine Dry Tortugas with a stop at Everglades National Park. The two parks are relatively close. The drive from Key West back to the mainland passes right by the Everglades.

Even with only a couple of hours, the Everglades offers excellent wildlife viewing. The Anhinga Trail is a boardwalk through a wetland environment. Alligators, turtles, birds, and other animals are easily spotted. It is a quick and easy way to experience a completely different Florida ecosystem.

Conclusion

Dry Tortugas delivers on its tropical desert island promise. And it does so without the crowds of a lot of other national parks. Fort Jefferson is massive and full of history. The waters are clear and full of life. The skies are dark and full of stars.

Adding the laid-back atmosphere of Key West on top of the park experience makes for a perfect trip. A little adventure. A little relaxation. There is nothing wrong with that.

The park is not the easiest to reach. The ferry is expensive and takes time. The seaplane is even more expensive. Camping requires carrying everything in. But for those who make the effort, the reward is one of the most unique national park experiences in America.

Pirate-era shipwrecks. Spectacular coral reefs. A Civil War fort. Tropical islands. Crystal clear water. Dark night skies. Dry Tortugas has it all. And it is waiting for those willing to travel 70 miles over open ocean to find it.
