Dry Tortugas National Park is one of America’s most remote and captivating destinations, accessible only by boat or seaplane, and home to a mix of history, crystal-clear waters, and rare wildlife. Located about 70 miles west of Key West, Florida, the park is spread across seven small islands and covers 100 square miles, most of it open water. It’s best known for Fort Jefferson, one of the largest masonry forts in the world, and its turquoise waters that make snorkelling and diving an unforgettable experience.
According to the National Park Service, only around 80,000 people visit Dry Tortugas each year, making it one of the least-visited but most exclusive national parks in the United States. The limited access and pristine environment make every trip feel like a private adventure.
1. Explore Fort Jefferson
Standing on Garden Key, Fort Jefferson is a massive coastal fortress built in the mid-1800s. With over 16 million bricks, it’s one of the largest forts ever constructed in the U.S. Despite never being fully completed or engaged in battle, it played an important role as a Union outpost during the Civil War. Walking through its arched corridors, you’ll find everything from massive cannon mounts to old prison cells. Admission to the park includes fort access, and ranger-led tours offer in-depth stories about its history.
2. Snorkel in Pristine Coral Reefs
Dry Tortugas is a snorkelling paradise, with coral gardens just steps from the shore. The waters are so clear that visibility often exceeds 50 feet, letting you spot parrotfish, angelfish, and even hawksbill sea turtles. Popular spots include the Moat Wall and the South Coaling Dock Ruins, both offering easy access from Garden Key. Equipment rental in Key West typically costs around $15–$20 per day before your ferry ride.
3. Go Birdwatching in a Migratory Hotspot
This island chain is a vital stopover for migratory birds traveling between North and South America. From March to May, you can see thousands of sooty terns nesting on Bush Key—the only place in the U.S. where they breed. Other rare species like the magnificent frigatebird and brown noddy also make appearances. Birdwatching here is free with your park ticket, but binoculars are a good investment if you want to catch the details.
4. Kayak Through Clear Waters
While the park doesn’t rent kayaks onsite, bringing your own (or booking a guided tour from Key West) opens up a whole new way to experience Dry Tortugas. Paddling through the shallow turquoise waters lets you explore hidden coves and spot rays gliding just below the surface. It’s one of the best ways to get a personal, peaceful perspective of the islands. Be aware of weather forecasts, winds and currents can be strong.
5. Dive Into History with Shipwrecks
Beneath the waves around Dry Tortugas lies a treasure trove of shipwrecks. The most famous is the Windjammer, a 261-foot, three-masted ship that sank in 1901. The site is perfect for intermediate divers and is rich with marine life, from lobsters to barracuda. Diving tours from Key West range from $150 to $200 per person and include equipment.
6. Camp Under the Stars
For the truly adventurous, camping on Garden Key offers one of the most unique overnight experiences in America’s national parks. With only 11 campsites, reservations are scarce and book months in advance.

Camping costs $15 per night, in addition to ferry or seaplane fees.
