Ardabil Airport — Ardabil, Iran

Ardabil Airport, in Iran's northwestern Ardabil Province near the border with Azerbaijan, has only one runway at a high 4,315 feet above sea level. Ardabil Province sits close to the Caspian Sea's western edge, with terrain considerably cooler and higher than much of central Iran. The city of Ardabil itself is one of the province's larger population centers, drawing on the airport for most of its air travel needs. Direct flights link the field to Tehran, cutting down significantly on a mountain drive that would otherwise take many hours through winding roads across this elevated region.
