Circle Hot Springs Airport in Central, Alaska

Circle Hot Springs Airport: Interior Alaska's Historic Hot Springs Destination

Circle Hot Springs Airport serves the historic Circle Hot Springs resort area in the Yukon Flats region of Interior Alaska, accessible from Central via a spur road. Circle Hot Springs was a legendary Alaska destination throughout the 20th century — the naturally occurring hot springs in the boreal forest of the Interior were developed into a resort that drew visitors from Fairbanks and beyond for their therapeutic waters in one of Alaska's most extreme climates. The resort and its airstrip enabled pilots to fly directly to the springs for weekend getaways from Fairbanks, representing the quintessential Alaska bush flying recreational tradition. The resort has experienced varying fortunes over the decades, with periods of closure and reopening.

The airport supports access to the Circle Hot Springs area whether or not the resort is in full operation, providing a base for hunting and fishing in the surrounding Yukon Flats country and access for those seeking the historic springs experience. Interior Alaska private pilots have historically used Circle Hot Springs as a classic bush flying destination — a place reachable only by aircraft or a long drive on the Steese Highway system, representing the independence that Alaska private aviation culture celebrates. Alaska DOT&PF maintains the airport as part of its Interior Alaska inventory, and the FAA Alaskan Region provides airspace oversight for the Circle District aviation corridor.
