Dry Tortugas National Park Trip: Ferry, Fort and Camping
Seventy miles west of Key West, with no road and no scheduled boat other than one ferry. The Yankee Freedom crosses in about two and a quarter hours, leaves in the morning and returns late afternoon, and includes breakfast, lunch, snorkel gear and the park entry fee in the fare. That buys roughly four and a half hours on Garden Key, which is enough for Fort Jefferson and a long snorkel. Seaplanes take 40 minutes and cost more. Camping is the best version of this trip and the hardest to book, with only a handful of primitive sites and no water on the island.
Getting there
- The ferry. One operator, one sailing a day, out of the Key West Historic Seaport. Two and a quarter hours each way, and the fare covers breakfast, lunch, snorkel gear, a fort tour and the park fee. It sells out weeks ahead in winter and spring, and it cancels outright when the seas are up. Book directly and book early.
- The seaplane. Forty minutes over the flats, with a view of shipwrecks on the way. Half day trips give you about two and a half hours on the island, full day trips around six. It costs roughly double the ferry and it is the only option if you are prone to seasickness.
- Your own boat or a charter. Possible, and the only way to reach Loggerhead Key, which has the best snorkelling in the park and no day visitors.
There is no way to visit Dry Tortugas from mainland Florida in a day. Key West itself is four hours from Miami by road, so plan two nights there around the crossing.
What you do with the day
- Fort Jefferson, the largest brick masonry structure in the Americas, built from roughly 16 million bricks between 1846 and 1875 and never finished. Walk the top tier for the full circuit view, and see the cell where Dr Samuel Mudd was held after the Lincoln assassination.
- Snorkel the moat wall, which is the easiest entry and full of fish within 20 feet of the sand.
- Snorkel the south coaling dock ruins, the better site: pilings in 15 feet of water with barracuda, tarpon and sometimes a nurse shark under them. It is a short swim and the current is real, so watch it.
- Walk the beaches, which takes 20 minutes, because Garden Key is 14 acres.
- Birding, if it is April. Bush Key next door holds a nesting colony of sooty terns and closes to visitors for the season, roughly February to September, and spring migration drops exhausted songbirds onto the fort in numbers that draw birders from across the country.
Camping, which is the real trip
There are only a handful of primitive sites on Garden Key and they are the best national park campsites in Florida. You get the fort at sunset, a night sky 70 miles from the nearest streetlight, and the island to yourself between the afternoon ferry leaving and the next one arriving.
The rules are strict because they have to be.
- Reserve online through recreation.gov. Sites are limited, the window opens months ahead, and they go quickly.
- Carry every drop of water. There is none on the island, and a gallon per person per day is the floor in that heat.
- Carry all your food, fuel and shade. Bring a tarp, because the sites have little of their own and the sun is relentless.
- Pack out everything, including waste you would normally bin.
- The ferry limits camper numbers per sailing and charges extra for camping gear, so coordinate the boat and the campsite together rather than in sequence.
When to go
- March to May: the best window. Warm water, lighter winds than winter, and April for the bird migration.
- December to February: pleasant on land, but cold fronts bring wind that cancels sailings. If your trip has no spare day, this is the risk.
- June to August: calmest seas and clearest water, and brutal heat with no shade.
- September to November: hurricane season, and the ferry stands down for named storms.
Whatever the month, build a spare day into your Key West stay. A cancelled crossing with no flexibility means the trip does not happen at all.
What to bring
Reef safe sunscreen, a rash vest or long sleeved shirt for the water, water shoes for the coaling dock rocks, more water than the ferry provides, and a dry bag. The ferry supplies mask, snorkel and fins, but bring your own mask if you have a prescription one. There is no shop, no cafe and no phone signal on the island.
Where it fits in a Florida trip
Dry Tortugas pairs naturally with the Everglades and Biscayne, which puts three national parks in one week out of Miami. Our East Coast national parks road trip has the full line, and the Everglades kayaking weekend covers the paddling half.
