Dry Tortugas Camping Reservations

Camping at Dry Tortugas National Park is one of the most unique outdoor experiences in the United States. You're 70 miles from civilization, surrounded by crystal-clear water, sleeping under some of the darkest skies in the eastern U.S. But getting a campsite requires planning. Here's everything you need to know.

The Basics

Dry Tortugas has 8 to 10 primitive campsites on Garden Key, the same island where Fort Jefferson stands. That's it — no overflow sites, no backcountry camping on other keys, no alternatives.

Each site accommodates up to 6 people and 2 tents. The total camping capacity for the entire park is roughly 60 people per night.

There is no fresh water, no electricity, no showers, no food service, and no store. You must bring everything you need — and take everything back out.

How to Reserve a Campsite

Camping reservations are managed through recreation.gov, not through the Yankee Freedom III ferry company. These are two separate bookings:

1. Campsite reservation on recreation.gov — reserve as early as possible
2. Ferry ticket on the Yankee Freedom III — book separately

Important: Having a campsite reservation does NOT include ferry transportation. You need both.

Reservation Timeline

• Campsites open for booking 6 months in advance on recreation.gov
• Peak season sites (March-May) sell out within days of opening
• Set calendar reminders for exactly 6 months before your target dates

Reservation Cost

• $15 per night — one of the best deals in the national park system
• Plus the Dry Tortugas National Park entrance fee (currently included in the Yankee Freedom ticket price for day-trippers)

What to Bring

Since there are zero amenities, your packing list is critical:

Water (Most Important)

• One gallon per person per day minimum
• More in summer heat (1.5-2 gallons)
• There is no freshwater source on the island

Food & Cooking

• All food for your stay plus backup meals
• Camp stove (ground fires are prohibited)
• Fuel canisters
• Cooler with ice (it will melt — plan accordingly)
• All cooking and eating utensils
• Trash bags for everything (pack it in, pack it out)

Shelter & Sleeping

• Tent with strong stakes (it's windy)
• Sleeping bag or sheets (depending on season)
• Ground pad or air mattress
• Shade structure or tarp (limited shade at most sites)

Sun & Water Protection

• High-SPF reef-safe sunscreen
• Wide-brim hat
• UV-protective clothing
• Snorkel gear (the water is right there)

Other Essentials

• Headlamp/flashlight (no ambient light at night)
• First aid kit
• Insect repellent (mosquitoes can be brutal, especially in summer)
• Biodegradable soap
• Toilet paper (composting toilets are available but basic)

Getting Your Gear There

The Yankee Freedom III allows campers to bring gear, but there are limits:

• Each camper gets space for one large container (like a cooler or storage bin) plus personal bags
• Loading happens dockside before departure
• Heavy items may require a hand cart (the ferry crew can help)
• Garden Key has a dock — you won't need to wade ashore

Some campers use large rolling coolers as their primary storage. Collapsible wagons are popular for moving gear from the dock to the campsite (about a 5-minute walk).

Campsite Details

Location

All campsites are on the south side of Garden Key, between Fort Jefferson and the beach. Most sites have:

• A picnic table
• A grill (charcoal only)
• Access to composting toilets
• Direct beach access

Shade

Minimal. Some sites have partial tree cover, but most are exposed. Bring your own shade structure.

Wind

Garden Key is flat and exposed. Expect steady trade winds, especially in winter and spring. This is great for keeping bugs away but means you need solid tent stakes.

Ground

Sandy with some hard-packed areas. Sand stakes work better than standard tent stakes.

The Camping Experience

Sunset & Sunrise

Without light pollution, the colors are extraordinary. The sun rises over Fort Jefferson and sets over the open Gulf — you get both from the campsite.

Stargazing

Dry Tortugas is a Bortle Class 2 dark sky site. On a clear night, you'll see:

• The Milky Way in vivid detail
• Satellites crossing overhead
• More stars than you've likely ever seen
• Bioluminescence in the water

Snorkeling

The campsite beach has excellent snorkeling right off shore. Without the time constraint of a day trip (the ferry leaves at 2:45 PM), overnight campers can snorkel at dawn, dusk, and anywhere in between.

Fort Jefferson

After the day-trippers leave on the afternoon ferry, you'll have Fort Jefferson essentially to yourself. Exploring the massive fort in the evening light, with no crowds, is worth the camping hassle alone.

Best Months for Camping

Rating	Months	Why
Best	March, April	Mild temperatures, low bugs, calm seas
Good	May, November	Warm but manageable, moderate availability
Challenging	June-August	Extreme heat, mosquitoes, storms
Variable	September-October	Hurricane risk, heat
Cold	December-February	Cold fronts, rough seas, chilly nights

Tips from Experienced Campers

1. Freeze water bottles — they serve as ice packs for your cooler and become drinking water as they melt
2. Bring a hammock — perfect for afternoons in the shade
3. Arrive on the first ferry — get settled before the midday heat
4. Snorkel the moat wall — the best snorkeling is along the fort's exterior wall
5. Stay two nights — one night feels rushed; two nights is the sweet spot
6. Watch the nurse sharks — they patrol the dock area at dusk
7. Bring a star chart or app — the dark skies deserve proper stargazing
8. Pack earplugs — sooty terns are loud and active at night during nesting season (April-September)

Cancellations and Availability

Like ferry tickets, campsite reservations do get cancelled. If your target dates are full on recreation.gov, check back frequently — cancellations appear with no advance notice.

For the ferry portion, set up an alert to catch ticket openings automatically. Getting both a campsite and ferry tickets on the same dates requires some coordination, but it's absolutely doable with persistence.

The Alternative: Just Do a Day Trip

If camping logistics seem overwhelming, a day trip is still an incredible experience. You get about 4.5 hours on the island — enough to tour Fort Jefferson, snorkel the moat, and eat lunch on the beach.

The Yankee Freedom III includes breakfast and lunch, snorkel gear, and a narrated tour. For most visitors, a day trip is the right choice.

But if you want the full experience — the stargazing, the empty fort, the sunrise snorkeling — camping is unmatched.

Getting Started

1. Check campsite availability on recreation.gov (6 months out)
2. Book your ferry on the Yankee Freedom III site, or set up an alert if it's sold out
3. Start your packing list early — you don't want to forget anything 70 miles from shore

The combination of camping + ferry can be tricky to coordinate, but the payoff is one of the best national park experiences in the country. Plan ahead, pack smart, and prepare for a trip you won't forget.
