Adirondack Regional Airport (IATA: SLK, ICAO: KSLK, FAA LID: SLK) is a public use airport located four nautical miles (5 mi, 7 km) northwest of the central business district of Saranac Lake, in Franklin County, New York, United States.

[1] The airport is owned by the Town of Harrietstown[1] and is situated in the north-central Adirondacks two miles (3 km) from Lake Clear.

However, after countless reviews of area maps, a plateau large enough for airport purposes was identified within a few miles of Saranac Lake Village.

The ideal site which these men had spotted on the map was part of the holdings of the Paul Smith's Electric Company.

With the requirement of public ownership thus complied with, events moved swiftly toward the realization of an airport for the Adirondacks.

Through persistent effort on the part of various citizens, who maintained close contact with Washington, D.C., the site was inspected and federal expenditures for construction of a Class III airport were approved.

The Town of Harrietstown issued bonds to augment the available funds and erected a terminal building in 1948 and a 100 by 100-foot (30 m) hangar in 1950.

[5][6] In 2000, the Federal Aviation Administration cited Adirondack Regional Airport for several violations, including failure to conduct monthly fire-and-rescue training and triennial full-scale emergency exercises, faded markings on the taxiway, cracked pavement on runways and the taxi-way, and broken lights.

[13] Adirondack Regional Airport covers an area of 1,499 acres (607 ha) at an elevation of 1,663 feet (507 m) above mean sea level.

For the 12-month period ending May 31, 2018, the airport had 6,940 aircraft operations, an average of 18 per day: 72% general aviation, 27% air taxi, and <1% military.
