Ferry, seaplane or private boat
The park is remote by design. The concession ferry provides a full travel day and carries both day visitors and a limited number of campers. The concession seaplane offers shorter transit and aerial views, with half-day and full-day formats. Private boaters gain flexibility but assume responsibility for weather, navigation, fuel, permits and self-sufficiency.
Choose based on more than price. Travelers prone to seasickness may value the shorter flight, while ferry passengers often prefer the longer time structure and included onboard services. Weather can affect either option. Book through the operator linked by the National Park Service and read cancellation, baggage and check-in terms before paying.
Pack for a place with no backup store
Garden Key has no public restaurant, hotel, potable-water system or general store. Day visitors should carry drinking water, sun protection, secure footwear and any medication they may need. A dry bag protects electronics and travel documents. Snorkeling is accessible from shore, but conditions and closures should guide the decision to enter the water.
Do not rely on cellular service. Download your confirmation and park map, tell someone your plan, and keep essential phone numbers offline. Pack out everything you bring. Wildlife, coral, shells, artifacts and historic materials must remain where they are.
- Stay in Key West the night before an early check-in.
- Bring a light layer for the crossing or flight.
- Use a reef-conscious sun strategy: clothing, shade and compliant sunscreen.
Give Fort Jefferson and the water separate time
A satisfying day has two anchors: explore Fort Jefferson and spend unhurried time along the shoreline. Rushing directly from one activity to the next misses the scale of the fort and the quiet that makes the park unusual. Check the visitor center for ranger guidance and current closures first.
Ferry passengers must return on the vessel’s schedule; seaplane passengers follow their assigned departure. Set an alarm well before boarding time and allow time to rinse, change and repack. The island is small, but a missed departure is a serious problem in a remote park.
