Kefalonia: The Majestic Giant of the Ionian Sea
Kefalonia is an island of grand scale and cinematic beauty. As the largest of the Ionian islands, it is a landscape of towering mountains (Mount Ainos), deep underground caves, and beaches that consistently rank among the best in the world. Famous as the setting for ‘Captain Corelli’s Mandolin’, Kefalonia offers a diverse experience that ranges from the upscale harbor of Fiskardo to the wild, horse-inhabited peaks of the interior. In 2026, it remains a top-tier destination for nature lovers, foodies, and those seeking a refined Mediterranean lifestyle.
Things to know about Kefalonia
Geographically, Kefalonia is located in the central Ionian, characterized by its high mountains and unique geological phenomena (like the sinkholes of Argostoli). Historically, it was a Venetian and British protectorate before joining Greece. An ideal trip length is at least 7-10 days. It is famous for Myrtos Beach, Melissani Lake Cave, and its unique Robola wine. The island is also home to the endangered Loggerhead sea turtles (Caretta caretta), which nest on its southern shores.
Top attractions in Kefalonia
Myrtos Beach
The most famous beach in the Ionian, Myrtos is a crescent of dazzling white pebbles at the foot of two sheer mountains. The water color here ranges from electric blue to deep sapphire and is truly a site of natural wonder. The sunset from the cliffs above Myrtos is one of the most spectacular in Greece.
Melissani Lake Cave
A geological marvel, this underground lake was discovered when its roof collapsed. At midday, the sun shines directly into the cave, turning the water a brilliant, glowing blue. Visitors take a small boat tour through the cave to see the stalactites and the crystal-clear water.
Fiskardo Village
The only village that was not destroyed by the 1953 earthquake, Fiskardo is a beautifully preserved Venetian harbor. It is the most upscale part of the island, lined with luxury yachts, high-end boutiques, and some of the best seafood restaurants in the Ionian.
Assos Village and Castle
Assos is a picturesque village built on a narrow neck of land connecting a rocky peninsula to the mainland. It is topped by a massive 16th-century Venetian castle. The village’s pastel-colored houses and quiet bay make it one of the most romantic spots on the island.
Mount Ainos National Park
The highest mountain in the Ionian (1,628m) is home to the unique Kefalonian Fir tree and a small population of wild horses. A drive to the summit offers a view of almost all the Ionian islands and even the Peloponnese.
Drogarati Cave
Located near Sami, this massive cave is over 150 million years old. It features impressive stalactites and stalagmites and a large chamber known as the ‘Apotheosis Room,’ which has such incredible acoustics that it occasionally hosts concerts.
Argostoli and the De Bosset Bridge
The capital of the island is a vibrant town built around a lagoon. The De Bosset Bridge is the longest stone bridge over the sea in the world. In the mornings, you can see the Caretta caretta turtles swimming near the fishing boats at the harbor.
Petani Beach
Located on the Paliki peninsula, Petani is often compared to Myrtos. It features the same white pebbles and dramatic cliffs but is usually less crowded. The water is exceptionally deep and clear, and the taverns on the beach are excellent.
Saint Gerasimos Monastery
The spiritual center of Kefalonia, dedicated to the island’s patron saint. The monastery houses the relics of Saint Gerasimos and features a beautiful new church with impressive Byzantine-style murals. It is surrounded by vineyards where the Robola wine is produced.
Skala and the Roman Villa
Skala is the island’s main tourism hub in the south, known for its long sandy beach. It is also the site of an ancient Roman villa with well-preserved mosaic floors depicting mythological scenes, offering a look at the island’s Roman past.
