Hydaburg Seaplane Base (IATA: HYG, ICAO: PAHY) is a small public-use seaplane base located in Hydaburg, a remote community on Prince of Wales Island in southeastern Alaska. It serves as a vital air transportation link for residents of Hydaburg, which is not connected to the broader Alaska road system. The facility accommodates floatplanes and seaplanes that provide essential passenger and cargo services to this isolated Haida community. Air travel is the primary means of reaching Hydaburg, making the seaplane base a critical piece of local infrastructure. The base is owned and operated under public authority and handles a small volume of traffic typical of bush aviation in rural Alaska. Scheduled and charter floatplane operators serve the community, connecting it to larger hubs such as Ketchikan.
