About Charlotte Amalie Harbor Seaplane Base

Charlotte Amalie Harbor Seaplane Base is the seaplane gateway serving Charlotte Amalie and the island of St. Thomas in the U.S. Virgin Islands. Also known as St. Thomas Seaplane Base, it is owned by the Virgin Islands Port Authority and sits directly on the harbor in the heart of the capital's downtown area.

The base provides scheduled inter-island seaplane service between St. Thomas and Christiansted, St. Croix, operated by Seaborne Airlines. Its single terminal, the Charles F. Blair Jr. Seaplane Terminal, is a compact waterfront facility named for the aviation pioneer and founder of Antilles Air Boats. The base uses two water landing areas on the harbor rather than traditional runways.

Located in downtown Charlotte Amalie, the seaplane base is within easy reach of the city's shops, restaurants, and cruise ship docks. It sits next to the Edward Wilmoth Blyden IV Marine Terminal, making it convenient to connect between seaplane and ferry travel to nearby islands.

Although the base is small and primarily focused on regional seaplane operations, its central waterfront location makes it a practical gateway for travelers moving between St. Thomas and St. Croix, with taxis, local transport, and road links available nearby for onward journeys across the island.
