San Sebastián Airport — Hondarribia, Spain

San Sebastián Airport, coded EAS, is located in Hondarribia, a town near the French border in Spain's Basque Country, serving the nearby city of San Sebastián (Donostia) despite being named for it. The airport's short runway, hemmed in by hills and the Bidasoa River estuary, limits it to smaller regional aircraft and makes it one of Europe's more technically demanding approaches for pilots. It offers a handful of domestic Spanish routes, mainly to Madrid, since many Basque Country travelers instead use the larger Bilbao airport or cross into France to use Biarritz airport, which is actually closer to San Sebastián by road in some cases. EAS remains valued locally for convenience despite its constrained capacity.
