Dry Tortugas National Park lies about 70 miles west of Key West in the Gulf of Mexico. Its seven small islands are surrounded by reefs and open water, and the park can be reached only by boat or seaplane. On Garden Key, explore Fort Jefferson, a vast, unfinished 19th-century coastal fort. In the water, look for coral and tropical fish while snorkeling, or spend time on the sandy beaches. Getting there takes planning: book transport well ahead and allow a full day for the trip.
Reaching the islands from Key West
Dry Tortugas National Park is about 70 miles west of Key West, beyond the end of the Florida Keys. The park covers around 100 square miles, most of it water, and includes seven small islands. There is no road connection: visitors reach the park by boat or seaplane.
For a boat trip, the journey from Key West takes roughly two to two and a half hours each way. That travel time makes this a full-day outing, not a quick stop between other Key West plans. Book your transport well in advance, since places can sell out months ahead. If you are considering standby travel, get there early. The open-water crossing can be bumpy, so prepare for the ride.
Fort Jefferson on Garden Key
Fort Jefferson occupies Garden Key and is the park’s central historic site. Construction began in the 19th century, but the six-sided coastal fortress was never completed. Its brick walls and broad scale give a sense of the military project built on this remote island.
You can explore the fort independently or join a guided tour. A guide can add context about the fort’s history and military role. On-site signs are limited, so print background information before leaving Key West if you plan to look around on your own. Allow time for the fort as well as the beaches and water; doing all three in a single day requires some planning.
Snorkeling, beaches and wildlife
The park’s shallow coastal waters, coral reefs and sandy shores are a draw in their own right. Snorkeling gives you a chance to see reef fish and coral, while swimming and beach time offer a slower way to spend part of the visit. Marine life in the surrounding waters includes a variety of fish, and the park is also known for its birdlife.
Garden Key has several beaches, including North and South Swim Beach. The reef and marine environment extend beyond the shoreline, so the park’s appeal is not limited to the fort or to land-based sightseeing. Plan your day around how much time you want in the water, especially if you also intend to take a fort tour.
What to plan before departure
There are no restaurants to rely on during your time in the park, and food on board may not be to everyone’s taste. Bring food for the day. Print useful information about Fort Jefferson in advance, and book your transport early rather than assuming a place will be available close to departure.
March and April are suggested as a time to visit before summer heat and stormier fall weather. Conditions on the crossing can still be rough, so be ready for open water. For a day trip, set aside time for the boat journey in both directions as well as the fort, snorkeling or swimming, and a meal.
