Getting to Garden Key is part of the Dry Tortugas experience: there are no roads, only a roughly 70-mile crossing from Key West by boat or seaplane. Both the Yankee Freedom ferry and Key West Seaplane Adventures arrive at the same remarkable little island—home to Fort Jefferson, swimming beaches, and easy-to-reach snorkeling—but they create very different days.

For most beach-minded visitors, the decision comes down to this: the ferry is the more relaxed, all-day outing with a much lower-cost format and included basics; the full-day seaplane is the better splurge if maximizing time on Garden Key matters more than the journey itself. Check current departure details, fares, and weather policies before you go, since operations can change.

At a glance: ferry vs. seaplane

  • Ferry: About 2 hours and 15 minutes each way, with roughly 4.5 hours on Garden Key. The usual day begins with a 7 a.m. check-in, an 8 a.m. departure, and return to Key West around 5:15 p.m., weather permitting.
  • Seaplane half-day: About 40 minutes each way and at least 2.5 hours on the island. It is a compact, scenic option with morning and afternoon departures.
  • Seaplane full-day: About 40 minutes each way and at least 6.5 hours on Garden Key. It is the clear winner for island time, but it is also the premium option.

The ferry turns transportation into a major part of the adventure. You have time to settle in, watch for birds and passing islands, eat breakfast on the outbound ride, and take advantage of included snorkel equipment, lunch, and a narrated Fort Jefferson tour. It is a long day, but it has an easy built-in rhythm.

The seaplane makes the crossing feel like a sightseeing flight. The aerial view of shallow water, reefs, and changing blues is a real highlight, and the short travel time means much less of your day is spent in transit. Current published seaplane adult rates are $527 for the half-day trip and $910 for the full-day trip, plus the park entrance fee for visitors age 16 and older unless covered by an eligible pass.

Which gives beach day-trippers the better Garden Key visit?

Choose the full-day seaplane if beach time is the priority. Six and a half hours gives you room to move at an unhurried pace: claim a patch of sand, snorkel along the shallow nearshore areas, dry off, explore Fort Jefferson, eat a picnic lunch, and return to the water without watching the clock. That extra two hours or so over the ferry is meaningful on a small island where swimming, snorkeling, fort exploring, and simply taking in the setting are all competing for attention.

Choose the ferry if you want the best overall first visit rather than the longest beach day. About 4.5 hours ashore is enough for a swim, snorkel, beach walk, fort tour, and lunch—especially if you pick one or two priorities. The ferry’s included meals and snorkel gear also simplify packing. Families, budget-conscious travelers, and visitors who like a guided structure often find it the more practical choice.

The half-day seaplane is best for travelers with limited time in Key West, people who strongly prefer to avoid a long boat ride, or anyone who wants the flight experience. But for a true beach-focused outing, 2.5 hours on Garden Key can feel brisk once you add changing, walking to the fort, and snorkeling. It is not the best fit if your ideal day means lingering in the water.

Camping changes the answer completely

If sleeping under Garden Key’s stars is on your list, take the ferry or arrange private-vessel transportation: the seaplane does not carry campers or camping equipment. The Yankee Freedom is limited to 10 camping passengers per day, and those spots can book far ahead. Its camping transportation program can accommodate stays of up to four days and three nights, while the park’s broader rules allow camping for up to 14 consecutive nights and no more than 30 nights in a 12-month period.

Garden Key camping is primitive, with no showers, public Wi-Fi, cell service, or electric hookups. Individual sites are first come, first served and hold up to six people and three two-person tents. A group site for 10 to 20 people requires an advance park reservation. The campground’s total capacity is 68 campers, so do not assume a last-minute private-boat arrival will be simple during busy periods.

Camping costs are separate from transportation: individual sites are $15 per night and the group site is $30 per night. Download the Recreation.gov app and set up payment before departure, since connectivity at the park is unreliable. Bring plenty of water, keep food in hard-sided containers, and plan to pack out all trash. A water-resistant phone pouch is useful for beach photos, while a pair of motion-sickness bands can be a smart ferry-day backup for sensitive travelers.

The bottom line

For the best value and a classic, well-rounded Dry Tortugas introduction, book the ferry. For the best Garden Key beach day—and the budget to match—book the full-day seaplane. Skip the half-day flight unless saving time or taking the aerial route matters more than having a long stretch on the sand. Whatever you choose, arrive prepared with sun protection, water, and a simple plan: snorkel early, explore the fort before the heat builds, then save time for one last swim.
