Kefalonia

Kefalonia is the largest of the Ionian Islands, with a mountainous interior dominated by Mount Ainos — a national park supporting a rare endemic fir species — and a coastline of deep-cut bays and dramatic limestone cliffs. The island's underground geography is notable for the Melissani Cave, where a collapsed roof allows sunlight to illuminate a turquoise underground lake, and the Drogarati Cave with its impressive stalactite chamber. Kefalonian Robola wine, produced from local limestone-soil vineyards, is among the more distinctive Greek white wines.
