National Park · Florida
A 70-mile boat or seaplane ride west of Key West to a Civil War fort ringed by coral reefs and turquoise water.
Field briefing
Dry Tortugas starts with access, not mileage.
Before you go
Go in the milder, calmer window from December to April; summer is hot and stormy, and fall carries hurricane-season cancellation risk. Most people come for a single day to tour Fort Jefferson and snorkel the reefs off Garden Key, but the eight first-come campsites turn it into a remarkable overnight under dark skies. There is no fresh water, food, or shade for sale out here, so pack everything: sun protection, plenty of water, reef-safe sunscreen, a snorkel set, and a windbreaker for the open-water crossing.

Conditions, crowds, and what each season asks you to pack.
80-85F
Highs around 80-85F, warm water, generally calmer seas than summer
Pack Reef-safe sunscreen, swimsuit, and a snorkel set, plus a windbreaker for the boat ride.
90F
Hot and humid, highs near 90F, midday sun is intense and afternoon thunderstorms build
Pack Sun shirt, hat, and far more water than you think you need (there is none to buy out there).
Highs in the upper 80s, hurricane season runs through November so trips can be canceled on short notice
Pack Flexible plans, rain layer, and electrolytes for the lingering humid heat.
75F
Mildest stretch with highs around 75F, but cold fronts can whip up wind and rougher crossings
Pack A warm layer and motion-sickness remedy for choppy, breezy boat days.
One of the largest 1800s masonry forts in the country; walk the moat wall and ramparts on Garden Key.
Shallow coral and the old coaling-dock pilings just offshore teem with fish, reachable straight from the beach.
The park's largest island and its lighthouse, reachable by kayak or private boat for quieter reefs.
Spring nesting grounds for sooty terns and frigatebirds, a magnet for birders (often closed to landing in season).
With zero light pollution offshore, campers get some of the darkest skies in Florida.
Lock the boat, ferry, tide, or water access first, then fit the route list around that schedule. For one day in Dry Tortugas, make Fort Jefferson the non-negotiable, add Garden Key snorkeling only if the first stop runs clean, and keep Loggerhead Key as the flexible finish.

Stay strategy
Make the access plan before the lodging plan.
Stay strategy
Dry Tortugas is 70 miles west of Key West, and that transport choice defines the trip. Most visitors sleep in Key West and go by ferry or seaplane. Garden Key camping is the only inside-the-park overnight, and it requires carrying every supply back and forth.
Compare base options
Read these as access plans first. The right base is the one that makes the transfer reliable, then the room or campsite can follow.
Book the ferry before anchoring lodging. Once that seat is confirmed, choose a Key West room that makes the early check-in painless.
The seaplane makes sense when time is tighter than budget. It is still a weather-dependent marine and aviation plan, so keep the day flexible.
Camping is the richest Dry Tortugas experience if you can handle the logistics. Reserve transport that allows camp gear and plan for heat, wind, and no resupply.
Book transport first
A Key West hotel does not matter until ferry, seaplane, or private boat access is solved.
Bring water
Garden Key has no fresh water for campers, so water planning is not optional.
Camping reservations
Campground systems change by season and sometimes by individual campground. Start with the official park camping page, then confirm open dates, reservation windows, and permit rules before booking.

Use this first for current campground status and park-specific rules.
Check for federal campground, backcountry, tour, and permit inventory tied to this park.

Make the transfer plan before the trail plan.
Weather windows, boat schedules, flight buffers, and backup days shape what is realistic.
Getting there
Fly in
Fly into Key West International (EYW), then reach the park by sea or air only, there is no road and no landing strip.
Transfer plan
The Yankee Freedom ferry makes the roughly 2.5-hour crossing from Key West to Garden Key once daily with breakfast, lunch, snorkel gear, and the entrance fee included.
Transfer plan
Key West Seaplane Adventures runs a 40-minute flight that gives aerial views of the reefs and shipwrecks.
Pair this with lodging: the best base is the one that protects the departure window, pickup point, or weather buffer.
The park is about 70 miles west of Key West and is accessible only by boat or seaplane. Most visitors take the Yankee Freedom ferry (a roughly 2.5-hour crossing) or a Key West Seaplane Adventures flight (about 40 minutes). Private boats can also make the trip and anchor in designated areas.
Yes, the entrance fee is $15 per person and is valid for 7 days, with children 15 and under free. In practice, the fee is normally included in the price of your ferry or seaplane ticket, so most visitors do not pay it separately. America the Beautiful and other federal passes are also accepted.
Yes. Garden Key has a small primitive campground with eight individual sites at $15 per night, offered first-come, first-served, plus one reservable group site. There is no fresh water, food, or store, so you must bring everything in and pack all trash out. The ferry carries only about 10 campers per day, so reserve that crossing months in advance.
December through April is the sweet spot, with milder temperatures, less humidity, and generally calmer conditions for snorkeling. Summer is hot and prone to afternoon thunderstorms, and fall falls within hurricane season, when trips can be canceled with little notice. Winter cold fronts can still bring wind and choppier crossings.
The big draws are touring Fort Jefferson, one of the largest 1800s masonry forts in the country, and snorkeling the coral reefs and old dock pilings right off Garden Key. Birdwatching is excellent in spring, and the park is also popular for fishing, paddling to Loggerhead Key, and stargazing if you camp overnight.
