Kärdla Airport — Kärdla, Estonia

Kärdla Airport (KDL) serves Kärdla, the largest town on Hiiumaa, Estonia's second-largest island in the Baltic Sea. KDL provides a vital link between Hiiumaa and mainland Estonia, primarily through scheduled flights to Tallinn, complementing ferry services that can be slower or disrupted by weather, particularly in winter when the Baltic Sea can be affected by ice. The airport supports both island residents dependent on the connection for work, healthcare, and commerce, as well as tourists visiting Hiiumaa's lighthouses, forests, and relatively untouched coastal landscapes. As with many small Baltic island airports, KDL operates a modest single-runway facility with limited daily flights, reflecting the island's small year-round population, though summer tourist demand adds seasonal variation to traffic levels.
