Why visit the Ionian Sea
The Ionian Islands sit in the western Greek archipelago, between mainland Greece and Italy. Compared to the Cyclades (Santorini, Mykonos), they are greener, with more dramatic vegetation, calmer water (no Meltemi wind), and a distinctly Venetian-influenced architecture from 400 years of Venetian rule. The islands are cosmopolitan and family-friendly, with strong British, Italian, and Greek influences.
1. Corfu (Kerkyra)
The largest and most culturally rich Ionian island. The Old Town of Corfu is a UNESCO World Heritage site since 2007 — a maze of Venetian-era streets, Italian-style cafes, and the dramatic 16th-century New Fortress and Old Fortress.
- Must-see: Spianada (the green square), Liston (arcaded promenade), Achilleion Palace.
- Best beaches: Paleokastritsa (turquoise coves), Glyfada (sandy and family-friendly), Sidari (Canal d'Amour rock formations).
- Day trip: Mount Pantokrator (906m, Corfu's highest point) and the Kanoni viewpoint.
- Stay: 4-5 days for full coverage.
2. Zakynthos (Zante)
Famous for Navagio Beach — the iconic shipwreck cove on Greek travel posters worldwide. The MV Panagiotis was beached here in 1980 and has been photographed millions of times since.
- Must-see: Navagio Beach (only by boat from Porto Vromi or by viewing platform), the Blue Caves on the north coast.
- Wildlife: Caretta caretta sea turtles nest on Laganas Bay (May-October). Marine reserve.
- Best beaches: Porto Limnionas, Gerakas Beach (turtle nesting), Banana Beach.
- Stay: 3-4 days.
3. Kefalonia (Cephalonia)
The largest Ionian island, made famous internationally by the novel and film "Captain Corelli's Mandolin" set in WWII Argostoli.
- Must-see: Myrtos Beach (perhaps Greece's most photographed beach), Melissani Cave (boat ride through underground lake with skylight), Drogarati Cave.
- Towns: Argostoli (capital), Fiscardo (Venetian harbor village), Assos (Venetian fortress).
- Stay: 4-5 days.
4. Lefkada
The only Ionian island connected to the mainland by a causeway — making it the easiest to reach by car. Less developed than Corfu and Zakynthos but with spectacular beaches.
- Must-see beaches: Porto Katsiki, Egremni, Kathisma — all on the western coast with white cliffs and turquoise water.
- Sailing hub: Lefkada Town and Nydri are major sailing-charter ports.
- Sappho's Leap: the cliff from which legend says the poet Sappho jumped — at Cape Lefkata.
- Stay: 3-4 days.
5. Ithaca (Ithaki)
The legendary kingdom of Odysseus in Homer's Odyssey. Small (96 km²), quiet, authentic — the antidote to over-tourism.
- Must-see: Vathy (capital harbor town), Filiatro Beach, Cave of the Nymphs (where Odysseus reportedly hid the gifts of the Phaeacians).
- Atmosphere: small fishing villages, very few large hotels, no airport.
- Access: ferry from Kefalonia (Sami) — 30-60 minutes.
- Stay: 2-3 days.
When to visit

- September-early October: warmest sea, fewer families, restaurants still open.
- July-August: peak season — crowded but lively.
- Off-season (November-April): many hotels closed, mild weather, very quiet.
