Dry Tortugas National Park, Florida: Best Things to Do – Top Picks

Did you know that 99% of Dry Tortugas National Park lies underwater? This remote paradise, located 70 miles west of Key West, is one of America’s least visited yet most spectacular national parks. With crystal-clear waters, vibrant coral reefs, and the massive 19th-century Fort Jefferson, Dry Tortugas offers an unparalleled adventure for those willing to make the journey.

Introduction to Dry Tortugas National Park

Dry Tortugas National Park encompasses 100 square miles, with only 1% above water. The park consists of seven small islands, with Garden Key being home to the impressive Fort Jefferson, the largest masonry structure in the Americas. The name “Tortugas” comes from the abundant sea turtles that Spanish explorer Ponce de León encountered in 1513, while “Dry” was added to warn sailors that the islands lacked fresh water.

This remote national park offers a unique blend of history, natural beauty, and marine adventure. From exploring the historic fort to snorkeling among colorful coral reefs, Dry Tortugas provides experiences you won’t find anywhere else in the United States.

Getting to Dry Tortugas National Park

Due to its remote location, reaching Dry Tortugas requires some planning. There are only two main ways to access the park: by ferry or by seaplane. Both options depart from Key West, so you’ll need to get there first.

By Ferry: The Yankee Freedom III

The Yankee Freedom III is a high-speed catamaran that makes daily trips to Dry Tortugas. The journey takes approximately 2.5 hours each way, giving you about 4.5 hours to explore the park. The ferry includes breakfast, lunch, snorkeling equipment, and a guided tour of Fort Jefferson in the ticket price.

• Departure: 8:00 AM from Key West
• Return: 5:15 PM to Key West
• Cost: Approximately $180-$200 for adults, $125-$140 for children
• Includes: National Park entrance fee, breakfast, lunch, snorkeling gear, and guided tour

By Seaplane: Key West Seaplane Adventures

For a faster and more scenic journey, seaplanes operated by Key West Seaplane Adventures make the trip in just 40 minutes. This option offers more flexibility with half-day or full-day excursions and provides spectacular aerial views of the Florida Keys and surrounding waters.

• Flight time: 40 minutes each way
• Options: Half-day (4 hours total) or full-day excursions
• Cost: $350-$650 per person depending on tour length
• Advantages: Less travel time, aerial views, smaller crowds
• Booking: Reserve several months in advance

Exploring Fort Jefferson

The centerpiece of Dry Tortugas National Park is the massive Fort Jefferson, one of the largest coastal forts ever built. Construction began in 1846 but was never completed despite 30 years of work. Built with over 16 million bricks, this impressive structure stands as a testament to 19th-century engineering and military architecture.

Self-Guided vs. Guided Tours

Visitors can explore Fort Jefferson through either a self-guided tour or by joining the guided tour included with the ferry ticket. The guided tour lasts approximately 45-90 minutes and provides fascinating insights into the fort’s history, including its role during the Civil War and its time as a prison that once held Dr. Samuel Mudd, who was convicted for aiding John Wilkes Booth after the assassination of President Lincoln.

Whether you choose to explore independently or with a guide, don’t miss the panoramic views from the top level of the fort. The vistas of turquoise waters stretching to the horizon are breathtaking, though be cautious as there are no railings along the edges.

Snorkeling and Beach Adventures

Dry Tortugas National Park is home to the third-largest coral reef system in the world, making it a premier snorkeling destination. The crystal-clear waters offer visibility up to 100 feet on calm days, allowing snorkelers to observe a vibrant underwater ecosystem teeming with marine life.

Best Snorkeling Spots

Several excellent snorkeling locations are accessible from Garden Key, each offering unique underwater experiences:

Dry Tortugas National Park serves as a crucial habitat for numerous bird species, making it a paradise for birdwatchers. The remote location of the islands provides an important rest stop for migratory birds crossing the Gulf of Mexico, especially during spring migration from April to May.

Bird Species to Watch For

Over 300 bird species have been documented in the park, with several rare species that can’t be found nesting anywhere else in the United States. Bush Key, adjacent to Garden Key, hosts one of the country’s only nesting colonies of sooty terns and brown noddies.

• Magnificent Frigatebirds – with their distinctive 7-8 foot wingspan
• Sooty Terns – nesting in colonies of up to 80,000 birds
• Brown Noddies – the only noddy species regularly found in the US
• Masked Boobies – graceful seabirds with precise diving abilities
• Roseate Terns – endangered species with pale plumage and black caps

Marine Wildlife

The waters surrounding Dry Tortugas are home to diverse marine life. While snorkeling or from the ferry, you might spot:

• Sea turtles – including loggerhead, green, and hawksbill turtles
• Nurse sharks – docile bottom-dwellers often seen resting under coral ledges
• Southern stingrays – gliding gracefully across sandy bottoms
• Goliath grouper – massive fish that can reach sizes of up to 800 pounds
• Colorful reef fish – parrotfish, angelfish, butterflyfish, and many more

The best time to spot sea turtles is during the summer nesting season when females come ashore to lay eggs on the beaches. Remember to maintain a respectful distance from all wildlife and never disturb nesting birds or turtles.
