Kefalonia is the largest of the Ionian islands, mountainous and green, and its beaches are defined by dramatic white-pebble bays and clear, deep-blue water. The most famous is Myrtos, a crescent of white pebbles wedged between two vertical mountains and one of the most photographed beaches in Greece. Its western twin is Petani, while the green amphitheatre of Antisamos near Sami is a third dramatic bay. Family sand sits around the Lassi resort at Makris Gialos and the pink-clay Xi, and the green northeast around Fiskardo hides the island's best snorkel coves. Browse every verified beach on the island on Kefalonia.
Kefalonia is large and its beaches are spread across separate coasts and mountain roads, so a car is essential and distances take longer than the map suggests. This is a curated best-of rather than the full list; the famous cliff bays are pebble rather than sand and the water gets deep quickly, so they suit confident swimmers more than toddlers.
