Dry Tortugas National Park

Almost 70 miles (113 km) west of Key West lies a cluster of seven islands, composed of coral reefs and sand, called the Dry Tortugas. Along with the surrounding shoals and waters, they make up Dry Tortugas National Park.

Accessible only by private boat, commercial ferry, or seaplane, the park is known the world over as the home of magnificent Fort Jefferson, picturesque blue waters, superlative coral reefs and marine life, and the vast assortment of bird life that frequents the area.

Fort Jefferson was built to protect one of the most strategic deepwater anchorages in North America. By fortifying this spacious harbor, the United States maintained a critical “advance post” for ships patrolling the Gulf of Mexico and the Straits of Florida. Nestled within the islands and shoals that make up the Dry Tortugas, the harbor offered ships the chance to resupply, refit, or seek refuge from storms.

The location of the Tortugas along one the world’s busiest shipping lanes was its most significant military asset. Though passing ships could easily avoid the largest of Fort Jefferson’s guns, they could not avoid the warships that used its harbor.

In enemy hands, the Tortugas would have threatened the heavy ship traffic that passed between the Gulf Coast (including New Orleans, Mobile, and Pensacola) and the eastern seaboard of the United States. It could also serve as a potential staging area, or “springboard” for enemy forces. From here they could launch an attack virtually anywhere along the Gulf Coast.

A powerful deterrent

Poised to protect this valuable harbor was one of the largest forts ever built. Nearly thirty years in the making (1846-1875), Fort Jefferson was never finished nor fully armed. It was a vital link in a chain of coastal forts that stretched from Maine to California. Fort Jefferson, the most sophisticated of these, was a brilliant and undeniable symbol that the United States wanted to be left alone. Though never attacked, the fort fulfilled its intended role. It helped to protect the peace and prosperity of a young nation.

During the Civil War, Union warships used the harbor in their campaign to blockade Southern shipping. The fort was also used as a prison, mainly for Union deserters. Its most famous prisoner was Dr. Samuel Mudd, the physician who set the broken leg of John Wilkes Booth.

Abandoned by the Army in 1874, the fort was later used as a coaling station for warships. In 1898, the USS Maine sailed into history, departing the Tortugas on its fateful mission to Havana, Cuba. Though used briefly during both world wars, the fort’s final chapter as “Guardian of the Gulf” had long since closed.

The ferry and seaplane drop off visitors at Garden Key and do not provide transportation to other areas of the park. Due to time constraints, Ferry and seaplane day visitors will not have time to visit Loggerhead Key.

To visit other areas of the park you must have your own mode of transportation and file a free boat permit with the park when you arrive.

Bringing your own boat to the Dry Tortugas National Park will provide you with the most opportunities to explore this remarkable national treasure.

If you plan on camping consider bringing a kayak or canoe. This will provide you with access to other areas of the park such as Loggerhead Key and great snorkeling sites. If you plan to take the Yankee Freedom Ferry, all camping plans including bringing a kayak must be coordinated through the ferry.

There are no boat rental services of any kind available in the park.

Depending on how you plan to visit Dry Tortugas National Park you may be required to obtain a permit. The following links provide additional information about the required permits at the park.

Boat Permits are required for all private boaters recreating in the park. Obtain a free boat permit at Park Headquarters on Garden Key. This must be done before recreating within the park (i.e. fishing, snorkeling, diving etc.)

Special Use Permits are required for special events such as weddings, first-amendment activities, privately owned (not for hire) seaplanes, meetings, group activities of 20 or more and non-profit organization activities, require special use permits.

Filming Permits are required for all commercial filming within the Dry Tortugas National Park.

Camping Reservations

The National Park Service does not take camping reservations for individual campsites. Designated campsites are on a first come first served basis with an overflow area available if needed. We do not turn away any campers when they arrive at Garden Key.
Parties of 10 or more wishing to reserve the group campsite are required to coordinate in advance.
Ferry passengers wishing to camp at Dry Tortugas National Park must coordinate and book their camping through the Yankee Freedom Ferry. The Ferry has a limited number of campers they can carry daily, so book early.
The seaplane concessionaire will not transport camping gear.

Boat Permits and Mooring Buoys

Boat permits are now required for all vessels in the park, including within the RNA. The only vessels exempt from this rule are those transiting the area without interruption. Vessels may only anchor overnight on sandy bottom within one nautical mile of the Garden Key Harbor Light. Within the RNA, vessels may use one of seven recreational mooring buoys for day use only. See information below on how to obtain a permit and how to use a Dry Tortugas mooring buoy.

Why are Boat Permits Necessary?

Permits are necessary to provide increased protection to the visitor, the Research Natural Area (RNA), and other marine resources outside of the RNA.
They also allow park staff to provide reliable information to the public about appropriate RNA visitation, provide park managers with reliable information about public use, increase the safety of the boating public by providing increased staff contact, and assist in monitoring recreational mooring buoy use to evaluate carrying capacity.
Boating permits are required for all recreational vessels including kayaks, paddleboards, dinghies, vessels operating under a Commercial Use Authorization (CUA), and commercial fishing vessels.
Vessels greater than 50 meters are required to obtain a Special Use Authorization in addition to the boating permit. Please contact Dry Tortugas National Park for more information.
NOTE: A permit is not necessary for vessels merely transiting through the park.

How and Where to Obtain a Boat Permit

Boating Permits are free and can be obtained in person at the Garden Key Visitor Center or Dry Tortugas National Park Headquarters Office, both located within Fort Jefferson.
Visitors will receive information about park rules and regulations, as well as information about things to do at the park.

How to Properly and Safely Use Mooring Buoys

Approach slowly from downwind/current.
To secure your boat to the mooring, run your line from a cleat on your boat through the loop in the end of the mooring pick up line and back to a cleat on your boat.
Use sufficient scope (rope length) to minimize pull on the anchor. Rule of thumb, if the buoy is being pulled underwater increase the scope.
If there is an upward pull on the mooring, increase the scope.
Sailboats should not leave sails up when they are tied to a mooring.
You are responsible for your vessel, inspecting the buoy, and checking that the buoy is holding as intended. Report any problems to NPS staff.
It is recommended to leave someone on the vessel at all times.
The mooring is designed to hold up to a 100-foot recreational vessel. It is intended to be used when weather and sea conditions are appropriate for the intended recreational use such as diving or snorkeling. It is not intended for use in all weather and sea conditions nor as a long-term mooring.

Mooring Balls

The mooring is designed to hold up to a 100 foot recreational vessel. You are responsible for your vessel, inspecting the buoy, and checking that the buoy is holding as intended. Report any problems to NPS staff. It is intended to be used when weather and sea conditions are appropriate for the intended recreational use such as diving or snorkeling. It is not intended for use in all weather and sea conditions nor as a long term mooring.

The Dry Tortugas National Park has much to offer. To reach this remote ocean wilderness one must travel by boat or plane over 68 miles of open sea. Visiting such an isolated place means that you need to be prepared, not only for rough seas, but for primitive conditions. There are no public phones, restrooms or snack bars.

Make sure you bring anything that you may need, such as protective clothing, sunscreen, or medication (especially for motion sickness). You will not be able to purchase these items in the park.


A designated snorkel area is located near the campground. Snorkeling along the outside of the moat wall or around the pilings of the south coaling dock is recommended.
Before snorkeling, make sure that all equipment fits properly. There are no guards on duty, so swim at your own risk. No swimming or snorkeling is permitted inside the moat.
An approved dive flag must be displayed at all times when snorkeling outside of the designated snorkel area.
For your safety never snorkel alone – always use the “buddy system”
If you need to stand up, stand on the sand. Never stand on coral or seagrass, as standing can kill these valuable resources.
Shipwrecks and all historic artifacts are protected by law.
Do not disturb coral or shells. All coral, living and dead, is protected from collection.


Questions to ask yourself:

Have you left your trip plans with a fellow camper?
Do you have a VHF radio?
What is your plan for self rescue?
How will you call for help if you need it?
How will you identify your location if you are able to contact searchers?
How will you signal searchers?
Do you have an anchor or sufficient line to tie off to buoys or markers to minimize drift?
Is the weather forecast for winds less than 10 mph and calm seas for the duration of the open water kayak trip?
What are the tides and currents? Are they favorable for your planned trip?
Does everyone in your group have open water kayak experience?
Are the kayaks sit-on-top self bailing kayaks?
Are the kayaks brightly colored?
Are you aware of landing areas and swim areas on Loggerhead Key?
Kayakers must be able to self rescue and reenter their kayaks. If you are unable to re-enter your boat you must be able to immediately call for help. If you call for help you must know or be able to describe your location. You must have a way to signal a searcher. Signals must be visible at night, in daylight, from a plane, or a boat.


Be cautious while recreating at the park. Do not approach marine life such as sharks, and jellyfish. These are wild animals that could actively or unknowingly cause harm.

Dry Tortugas National Park has three visitor centers.

Eco-Discovery Center

Due to the remoteness of this park the National Park Service has partnered with the National Oceanic and Atmospheric Administration (NOAA) at a visitor center in Key West.
Admission to the Visitor center is always FREE and open to the public Tuesday through Saturday 9am – 4pm.
The Eco-Discovery center is in the heart of Key West and easily accessible by bicycle or walking from downtown. If you drive parking is available as well.
Enter the Florida Keys Eco-Discovery Center and take a journey into the world of the native plants and animals of the Keys, both on land and underwater. Leave with an increased awareness and appreciation of the need to protect and conserve the ecosystem of South Florida.
The Center features over 6,000 square feet of interactive and dynamic exhibits including a mock-up of Aquarius, the world’s only underwater ocean laboratory.
Colorful marine artwork depicting the deep sea, coral reef, and mangrove shoreline decorates the outside wall of the Center, guiding you toward the main entrance.
Once inside, you can explore exhibits interpreting the ecology of Keys’ habitats, from the upland pine lands through the hardwood hammock and beach dune. From there, you’ll travel down to the mangrove shoreline, where you can enter the sea to learn about the seagrass flats, hard bottom, coral reef, and deep-shelf communities. Stop in to the Center’s theater to catch “Reflections of the Florida Keys,” a short film on the diverse ecosystem of the Florida Keys by renowned filmmaker Bob Talbot.
Be sure to check out the Mote Marine Laboratory Living Reef exhibit, which includes a 2,500-gallon reef tank with living corals and tropical fish, a live Reef Cam, and other displays that highlight the coral reef environment.
A walk through the Aquarius exhibit offers glimpses of the beautiful marine life at the reef and shows how scientists live beneath the sea during research expeditions.
And before you head out, stop by the on-site gift shop featuring fun and unique items such as books, games, and videos. Net proceeds from the sale of products are returned to the Center to support educational programs.
The Center is sponsored and operated by Florida Keys National Marine Sanctuary, NOAA, the South Florida Water Management District, Everglades and Dry Tortugas National Parks, and the National Wildlife Refuges of the Florida Keys.
Admission to the Florida Keys Eco-Discovery Center is free. Contact the Center at 305-809-4750 or FKEDC@noaa.gov.

The Bight Visitor Center

The Center is a free attraction managed by the Dry Tortugas NPS official Ferry Concession located in Key West Historic Seaport, known as the “Bight.”
Exhibits include an 11-foot diameter scale model of Fort Jefferson, an interactive photo mural that explores the history of the Bight and a Junior Ranger Exploration Station that allows children to get hands-on with and learn about the natural resources of the Dry Tortugas.
By touring the Center the Key West visitor will learn about one of our nation’s most unusual National Parks and Key West’s unique nautical heritage, whether they decide to visit the Park or not.

The Florida National Parks Association Bookstore

The Florida National Parks Association features books, videos, and related products about the flora, fauna, and history of Everglades, Biscayne, and Dry Tortugas National Parks and Big Cypress National Preserve. Net proceeds from the sale of products are returned to the National Parks to support park educational and visitor service programs.

Regardless of the time of year you choose to visit the park, it is highly stressed that you be informed of the weather. This is especially true for those traveling to the park in their own vessels. To see the National Weather Service offshore forecast for the area of the Dry Tortugas.

Winter Season

The Dry Tortugas experiences essentially two seasons. The winter season typically begins in November and runs through April. During these months, the predominate weather pattern is influenced by strong cold fronts from the North and West that generate large swells and windy conditions. Consecutive days of 20+ knot winds and seas of greater than 5 feet are not uncommon. For the visitor experience, this translates in to rough seas and poor visibility for snorkeling. The positive side is cooler weather, fewer crowds, and the opportunity to see many species of birds blown in with the passing fronts.

Summer Season

The summer season begins around May and runs through October. This period also encompasses the Atlantic hurricane season (June 1- November 30). Weather conditions are generally idealistic with little to no wind, and excellent visibility for snorkeling and viewing of marine life. Visitors are strongly encouraged to stay informed of the tropical weather state prior to scheduling a trip. Hurricanes can have a lasting effect on the park even if there is no direct impact. Information regarding park closures and other effects from severe weather will be posted on the park’s webpage.
