Plan three nights each on Lefkada, Kefalonia and Zakynthos: enter the first by road and leave the last by air. The two ferry days connect remote ports, so reserve the ground journeys as carefully as the boats. Each island has its own rental contract; the car does not automatically travel with you.
This is a seasonal planning route. Checked 21 October 2026: Ionion P. Lines says its 2026 services on both links have ended, with a May 2027 return expected and new schedules to follow. West Ferry publishes a separate Lefkada–Kefalonia programme. The full chain needs both links on your exact dates; one available boat is insufficient. Confirm the actual Lefkada port, as weather can move a sailing from Vasiliki to Nidri.
Use the full days for one western Lefkada beach, Kefalonia's northern villages and Melissani, then Zakynthos's northern coast and protected turtle habitat. Keep arrivals light. Corfu and Ithaca require extra time; adding them would displace the island days that make these nine nights useful.
