- A harbour airport, also known as a seaplane base or water airport, is an airport that is located on or adjacent to a body of water, typically a harbour or bay. Instead of traditional runways, these airports have water runways or ramps where seaplanes can land and take off.
- Harbour airports are often used for seaplane operations, which involve aircraft that can operate on both land and water. Seaplanes are equipped with floats or hulls that allow them to land and take off from water, making them ideal for accessing remote or hard-to-reach locations that do not have traditional airports.
- Harbour airports can be found in various locations around the world, particularly in coastal areas or regions with a large number of lakes and rivers. They are commonly used for tourism and recreational purposes, offering scenic seaplane flights and connecting passengers to resorts, islands, and other destinations that are inaccessible by land.
