Chalk's Key West Seaplane Airport – Legacy Water Operations at America's Southernmost City
Chalk's Key West Seaplane Airport carries the legacy of one of the oldest continuously operating airlines in American aviation history — Chalk's International Airline, which launched seaplane service to the Bahamas and Florida Keys in 1919. The Key West seaplane base connects to this storied tradition of amphibious aviation, where the turquoise waters of the Gulf of Mexico and the Atlantic meet at the island city's doorstep and provide a natural runway for floatplanes and flying boats. Key West's position at the tip of the Florida Archipelago makes water-based aviation a natural fit for island-hopping access.
Modern seaplane operations at Key West serve sightseeing, charter, and island-access missions, offering passengers views of the reef system, the Dry Tortugas National Park corridor, and the shallow backcountry of the Lower Keys that are impossible to appreciate from a conventional aircraft seat. Seaplane bases in the Florida Keys operate under special FAA regulatory provisions addressing waterway traffic coordination, marine mammal protection zones, and low-altitude environmental restrictions over the Florida Keys National Marine Sanctuary.
What is the history of seaplane operations at Key West?
Key West has hosted seaplane operations since at least 1919, when Chalk's International Airline inaugurated service. The U.S. Navy also operated extensive flying boat facilities at NAS Key West during World War II.
Can I charter a seaplane to the Dry Tortugas from Key West?
Yes. Seaplane charters to Fort Jefferson and the Dry Tortugas National Park are available from Key West, providing the fastest access to the islands roughly 70 miles west of Key West.
Are there environmental restrictions on seaplane operations in the Florida Keys?
Yes. The Florida Keys National Marine Sanctuary imposes low-altitude flight restrictions and designated landing zones for seaplanes to protect the coral reef ecosystem and marine mammals.
What types of aircraft operate from the Key West seaplane base?
Cessna Caravan amphibians and Cessna 206 floatplanes are common platforms for Keys seaplane operators. De Havilland Twin Otters on floats have also served the route historically.

Water Aviation Legacy and the Florida Keys Ecosystem
Key West's seaplane heritage runs deep. The U.S. Navy's patrol flying boat squadrons operated extensively from Key West during World War II, tracking German U-boat activity in the Florida Straits and Caribbean. Pan American Airways used Key West as a staging point for its legendary South American flying boat routes. Today's seaplane operations honor this legacy while navigating a far more environmentally conscious regulatory environment, with designated takeoff and landing areas that avoid the most sensitive coral and seagrass habitats.
The economic contribution of seaplane operations to Key West's tourism economy is significant. Day trips to the Dry Tortugas by seaplane provide a premium alternative to the slow ferry crossing, and reef-viewing scenic flights attract visitors from around the world. FDOT's aviation planning for Monroe County recognizes seaplane infrastructure as a unique component of the Keys' transportation system — one that has no direct equivalent elsewhere in Florida's aviation network.
