The Dry Tortugas is about 70 miles west of Key West: roughly a 2 to 2.5 hour crossing each way by fast private boat, longer by public ferry. It’s a national park, so an entrance fee applies, and there’s no food, water, or shops on the island, so you need to bring everything you’ll need for the day.
Distance and Travel Time
| Detail | What to Know |
| Distance from Key West | ~70 miles |
| Private/charter boat crossing | ~2 to 2.5 hours each way |
| Public ferry crossing | Longer, on a fixed daily schedule |
| Total trip length | Full day either way, given the round-trip crossing time |
Step 1: Choose Ferry vs. Private Charter
- Public ferry: runs on a fixed daily schedule, typically the most budget-friendly option, but locks you into a set departure and return time with limited flexibility.
- Private charter: more flexible on departure time and can adjust for weather, plus more room to add stops like snorkeling on the way, usually at a higher price point than the ferry.
Step 2: Budget for the Park Entrance Fee
The Dry Tortugas is a U.S. National Park, so a per-person entrance fee applies on top of whatever you pay for the boat or ferry. Fee amounts can change, so confirm the current rate with the National Park Service or ask your charter operator to include it in their quote so there’s no surprise on the day.
If your group wants a private boat, BYOB-friendly setup, and a sunset that actually feels like your moment (not a shared tour), book your boat charter in Key West at bteboatcharters.com/booking/ or call +1-305-912-2260. Sunset slots are limited and weekend dates fill early—check availability now.
Step 3: Pack Like There’s Nothing on the Island
This is the detail people most often underestimate: Fort Jefferson and Garden Key have no concessions, no shop, and no reliable drinking water. Everything you plan to eat or drink needs to travel with you.
- Plenty of water: more than you think you’ll need for a full day in the sun.
- Food for the entire day, since there’s nowhere to buy anything once you arrive.
- Reef-safe sunscreen, a hat, and sun protection: there’s very little shade outside the fort itself.
- Snorkel gear if your charter doesn’t provide it and you plan to get in the water.
Step 4: Time It With the Season
Winter through spring generally brings calmer water and more predictable crossing conditions. Summer can bring the same afternoon thunderstorm pattern common across South Florida, which is more disruptive to a fixed ferry schedule than to a private charter that can shift departure time around the forecast.
Step 5: Know What There Is to Do Once You Arrive
- Tour historic Fort Jefferson, one of the largest 19th-century coastal forts in the U.S.
- Snorkel the reef around Garden Key: some of the clearest, least-crowded water accessible from Key West.
- Birdwatch: the Dry Tortugas is a well-known stop for migratory seabirds.
