Dry Tortugas National Park Fort Jefferson

Last Updated on

During a vacation to the Florida Keys, I took a day trip from Key West to Dry Tortugas National Park on Garden Key, about 70 miles from Key West. With its white sand beaches and a secluded location, Dry Tortugas feels like a hidden paradise. But by far the best part of visiting here is that it’s the best snorkeling spot in Key West!

Haphazard Rating for Dry Tortugas National Park: (2 of 5).  Some areas recommended for experienced snorkelers; jellyfish spotted in the swimming area; bring Dramamine for the boat ride.
To See: A 19th-century fort, amazing beaches, snorkeling, primitive camping, a million nighttime stars
To Eat: Breakfast and lunch provided onboard the ferry or bring a picnic/cooler.  There are no restaurants on the island
When to Visit: All year, but be sure to book in advance; and be aware of the Florida hurricane season June – October

History of Dry Tortugas

The Dry Tortugas National Park encompasses 7 islands known for being the site of the 19th century Fort Jefferson.  It’s also home to clear blue water, many species of birds, and some of the least-disturbed coral reefs in the Keys.  This is due in part to its UNESCO designation as part of the Everglades and Dry Tortugas Biosphere Reserve.  And it turns out they got their name when Juan Ponce de Leon, the first known European to see the islands, visited in 1513.  He caught so many sea turtles that he then referred to the islands just as “Tortugas.”  The “dry” part was added because of the lack of fresh surface water on the islands.

Arriving at Dry Tortugas is awe-inspiring! The white beaches and blue waters are nothing short of spectacular.

Getting to Dry Tortugas

Dry Tortugas is accessible only by boat or seaplane. The cheapest way to get to the Dry Tortugas is by The Yankee Freedom Ferry, an authorized concessionaire of the park. Daily ferry trips to Dry Tortugas can be booked from Key West .  The trip includes a buffet breakfast and lunch onboard, bathroom facilities, and showers where you can rinse off. Also included is snorkeling equipment and a guided tour of the fort.  

It takes 2 hours each way to get to and from the island via ferry, which leaves about 5 hours of time at the island.  

Getting the Most Out Of Your Trip

To get the most out of your Dry Tortugas trip, I recommend camping! While the facilities are very basic, the gorgeous scenery far outweighs any negatives. During our day trip, we just didn’t have enough time to enjoy all the amazing snorkeling or take a tour of Fort Jefferson with the park rangers.

To camp, you must bring everything needed for your stay.   There is no food service, water, fuel or charcoal and only portable toilets after the ferry departs.   In short, you’ll have crunchy beach hair, but one of the most beautiful and remote beaches in the U.S. almost to yourself.

Unfortunately, you need to plan months in advance for the best availability at Dry Tortugas for camping: the Park actually recommends 8-12 months. If this doesn’t fit your schedule, still go for the day trip – and for your camping fix, out these other beach campgrounds in Florida.

Fort Jefferson History

Fort Jefferson is the largest masonry structure in the Americas, which is no small feat if you imagine that all of its 16 million bricks had to be hauled in by boat.  The U.S. purchased the land from Spain around 1820 and eventually built a fort there.  During the Civil War it was used a a prison for court-martialed soldiers and others, which later included four of the men convicted of Lincoln’s assassination.  In 1935 it was named a national monument, and in 1992 the fort and Dry Tortugas were designated as a national park.

A Day at Try Tortugas

Upon your arrival at Dry Tortugas, the park rangers give guided tours of the fort (included in the ferry trip).  

We wanted to spend our time in the water, so instead we walked the perimeter via walkways which separate the fort’s moat from the open water, and then headed to the beach.  The ferry provides a map of the best snorkeling spots.  We stayed along the fort wall of the south swim beach and the south coaling dock ruins, where the pilings of the old dock are overgrown with corals.  To reach the pilings, you need to swim out from the beach and around large rocks.  I’d recommend that area for experienced snorkelers.  It’s a little bit of a swim, and the waves were stronger than in the more protected beach cove.

Beware the tarpon, but only because you might mistake the largest ones for small sharks.  (I only inhaled a teensy bit of water via my snorkel!)  We saw some jellyfish as well.  Bring dramamine if boats give you trouble, and of course reef-safe sunscreen and a towel.

Dry Tortugas Camping

If you camp, you will need to bring everything you need for your stay.  I’ve included the checklist from Yankee Freedom below in the resource list.  The ferry will drop you off with all of your gear.  Depending on how long you book a campsite, you’ll then return on one of their subsequent trips.  The campers I saw returning looked sunburnt, grizzled and a little wild!  But it’s still on my bucket list to camp at least one night.

Visiting Dry Tortugas was one of my favorite days in the Keys, with easy beach-access snorkeling and a pristine setting.  Be sure to book early, as even the day trips sell out weeks in advance.  And consider camping to have the park and beach nearly to yourself.
