How Far in Advance Should You Book Dry Tortugas Ferry Tickets?

The number one question we hear: "How far in advance do I need to book the Dry Tortugas ferry?"

The short answer: as early as possible. But here's exactly what that means and what to do if you're already too late.

When Do Tickets Go on Sale?

Yankee Freedom III ferry tickets become available approximately 6-9 months before the sailing date. The exact window depends on the season and how far ahead the ferry company opens their calendar.

You can book online at drytortugas.com or call their reservation line at 305-294-7009.

How Fast Do They Sell Out?

It depends on the season:

Peak Season (March - June)

These months sell out 2-4 months in advance, sometimes faster. March and April are the worst — spring break demand, perfect weather, and bird migration combine to create a booking frenzy.

If you want a peak season date, book the day tickets become available.

Summer (July - September)

Summer dates typically sell out 1-3 months ahead. The heat and afternoon thunderstorms reduce demand slightly, but weekends still go fast.

Off-Season (October - February)

You'll usually find availability a few weeks out, and sometimes even same-week bookings are possible. The trade-off: rougher seas, cooler water, and the occasional cancellation due to weather.

Day Trip vs. Camping

This matters a lot. The ferry has limited spots for campers (you need to bring all your gear on the boat), and camping slots sell out much faster than day-trip seats.

• Day trip tickets: Book 2-4 months ahead during peak season
• Camping tickets: Book 6-9 months ahead — these go first

If you're camping, set a reminder for when tickets open and book immediately. See our camping reservations guide for the full breakdown.

What Day of the Week Sells Out First?

Based on our monitoring data:

1. Saturdays sell out first — families and weekend trippers lock these up early
2. Fridays go next — people extend long weekends
3. Weekdays are your best bet for last-minute availability

If you have any flexibility, aim for a Tuesday or Wednesday. You'll have a much easier time finding tickets and the island will be less crowded.

What If Your Dates Are Already Sold Out?

This is actually more common than getting tickets on the first try during peak season. Here's the good news: sold-out dates reopen regularly.

People cancel, change plans, or rebook. When they do, those seats go back into the booking system. The problem is they get snapped up fast — often within minutes.

You have three options:

1. Set Up a Ferry Alert

Dry Tortugas Alerts checks Yankee Freedom availability every 60 seconds. When a seat opens on one of your watched dates, you get a text message instantly with a link to book.

• $5 per date for a one-time alert (fires when your full ticket count opens)
• $10 per date for unlimited alerts (notified on every opening, even partial)

The more dates you watch, the better your odds.

2. Try the Standby Line

If you're already in Key West, you can try walking up the morning of. Show up at the ferry terminal (100 Grinnell St.) by 4-5 AM. A sign-up sheet goes out at 6:30 AM, and if there are no-shows, standby passengers board in order.

It's not guaranteed — some days nobody gets on, other days 10-15 standby passengers make it. There's no way to predict it.

3. Use Our Concierge Service

Don't want to deal with any of this? Our concierge service monitors availability and books for you automatically. You're only charged if we successfully book your tickets.

The Ideal Booking Timeline

Here's what we recommend:

When	What to Do
9 months out	Set a reminder for when tickets open
6 months out	Book immediately when your dates go live
3 months out	If sold out, set up a ferry alert
1 month out	Watch for increased cancellations as plans change
1 week out	Consider the standby line as a backup

Book Early Next Time

If you end up getting tickets through a cancellation alert, remember this experience. For your next trip, bookmark the Yankee Freedom booking page and set a calendar reminder for 6-9 months before your target dates.

Dry Tortugas is worth the effort. The 70-mile journey across open ocean to Fort Jefferson, the crystal-clear snorkeling, and the feeling of being on one of the most remote islands in the continental United States — it's unlike anything else in the national park system.

Set up an alert and we'll help you get there.
