Why Are the Ionian Islands So Green?
Rainfall helps explain Ionian greenery, while elevation, local climate and cultivation shape each island differently.
More Rain, More Vegetation - Not Constant Rain
Higher rainfall is a major reason the Ionian Islands often look greener than islands in the Aegean: it supports taller, denser vegetation. That is a regional contrast, not a rule that every Ionian island is greener than every Aegean island.
Even small Ionian islets can carry dense woody growth, contrasting with the relatively bare appearance of many small Aegean islets. The difference is visible in the landscape, not just in Corfu’s reputation for greenery.
The Ionian climate is still Mediterranean, with hot, dry summers and mild, humid winters. A green hillside does not mean you should expect frequent summer rain.
Corfu Is Not Typical of Every Ionian Island
Across the archipelago, vegetation changes from north to south: from green Corfu towards more drought-adapted growth on Zakynthos and the Strofades. Height above sea level adds another contrast: coastal vegetation, evergreen woodland and mountain forests do not all have the same character.
That variation matters when looking at destination photographs. One wooded hillside cannot stand for the whole island group, just as a photograph of a bare coast cannot describe all of Greece.
Green Does Not Always Mean Untouched Landscape
Agriculture has also shaped the view. Extensive olive groves, terraced fields and Mediterranean scrub form much of the Ionian landscape; some terraces are now abandoned. Cultivated trees and less managed vegetation can occupy the same wider panorama.
Taken together, these differences suggest a better way to understand the scenery: rainfall helps explain the regional abundance of vegetation, while the particular island, elevation and history of cultivation help explain what that greenery looks like. The view is neither uniform nor entirely wild.
