Baranof Warm Springs Float and Seaplane Base (IATA: BNF) is a remote public seaplane base serving the small community of Baranof Warm Springs on the east coast of Baranof Island, Alaska. With no road access, it is reached only by floatplane or boat and serves as the gateway to natural hot springs, waterfalls, and Tongass National Forest trails. The facility is a simple water landing and dock rather than a traditional airport.
💡 Local Tip
Frequent visitors head to the upper hot springs pools near the waterfall rather than the first tubs by the dock—they are hotter, quieter, and less crowded, especially before day-trippers arrive from Sitka.
🚖 Getting There
Access is by air or sea only: most travelers connect through Sitka (SIT) and arrange a floatplane charter or boat transfer in advance. Scheduled service is limited, so confirm weather, baggage limits, and return times with your operator. Once at the dock, everything in Baranof Warm Springs is walkable via boardwalk and trails; there are no taxis or rental cars.
