Holidays by the Ionian Sea

Green hills, olive groves and pale cliffs give Greece's Ionian coast a character of its own. Corfu, Lefkada, Kefalonia and Zakynthos suit holidays that alternate between beaches, village lunches and drives through the landscape. Across the wider sea lie southern Italy and Albania's southern coast, offering other ways to explore this part of the Mediterranean.

Look beyond the beach photograph

Porto Katsiki on Lefkada shows the dramatic cliff-backed side of the Ionian. Around Corfu, the scenery changes between sandy stretches, rocky coves and wooded headlands. When choosing a base, check beach access: a beautiful bay reached by steps or boat may be less convenient for everyday family swimming.

Summer is the main beach season; spring and early autumn can suit a holiday with more sightseeing. Ionian sea temperature helps narrow down the month, while a beach's exposure to wind and waves helps narrow down the location. Clear-looking water in a photograph is not a promise of calm conditions on arrival.
