Calvi Sainte Catherine Airport — Calvi, France

Corsica's rugged northwestern coastline funnels a heavy seasonal crush of European sun-seekers through CLY each summer, a stark contrast to the quiet winter months when the airport reverts to serving a comparatively small local population. Calvi itself is dominated by a Genoese citadel overlooking the bay, along with beaches that draw French, Italian, and other European tourists chartering direct flights straight from their home countries during peak season. The airfield sits adjacent to Sainte-Catherine, from which it takes part of its name, and shares proximity with a base long used by the French Foreign Legion's parachute regiment, giving the area a distinct military as well as tourist character. A single runway, hemmed in by hills and coastline, handles a traffic pattern that swings dramatically between a bustling summer schedule and a sparse winter one.
