Ferry vs seaplane checklist
The park is remote by design. The National Park Service concession ferry (Yankee Freedom) is built around a full travel day and carries day visitors plus a limited number of campers. Key West Seaplane Adventures, the concession seaplane, offers shorter transit and aerial views in half-day and full-day formats. Private boaters gain flexibility but assume weather, navigation, fuel, permits and self-sufficiency.
Use this checklist before you pay: (1) Confirm the operator is the current NPS-linked concession. (2) Compare total time on Garden Key, not just ticket price. (3) Read baggage, soft-cooler, snorkel-gear and weight limits. (4) Note camper rules—ferry camper space is limited and seaplane camping logistics differ. (5) Protect an early Key West check-in and a backup weather day. (6) Save cancellation and refund terms offline. Travelers prone to seasickness may prefer the shorter flight; visitors who want a longer island day often choose the ferry.
- Ferry: longer day structure, camper transport option, depart from the Key West ferry terminal area.
- Seaplane: shorter transit, aerial views, depart from Key West International Airport—confirm check-in and baggage.
- Either option: stay in Key West the night before and do not cut the check-in window close.
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.
