Kefalonia is a very large island. The largest part of Kefalonia is mountainous, except for the southern side which has a valley, known as Levatho Valley. The coastline is also varied, from beaches with big white pebbles to coasts with soft fine sand.
The capital of Kefalonia is Argostoli. The most tourist places are Lassi, Sami, Skala, and Fiscardo. The southern side from Lassi to Skala has amazing sandy beaches with crystal water. Beaches on the northern side are pebbled, including Myrtos and Antisamos, the most famous beaches of the island.
There are two nice caves to visit in Kefalonia, both in the region of Sami: the lake cave of Melissani and the cave of Drogarati. Also nice is the Medieval Castle of Saint George in the village of Peratata.
Kefalonia is a family island. Due to its large size, tourism is spread and places do not get very popular, not even in August which is high season for Greece. There is little nightlife in Argostoli, Skala, and Fiscardo, but nothing excessive. Beaches are crystal and safe for children and it is easy to find accommodation.
However, as the island is very large and there are many places to see, a car is needed for easy transportation. Public buses are not that frequent and convenient. If you don't have your own car, it is advised to rent one at least for 2-3 days to explore the island.
Practical advice and tips
Arriving at the port
Kefalonia has many ports. Poros serves ferries from Killini (Peloponnese, mainland Greece). Sami serves ferries from Patras, Italy, and Ithaca, while Fiscardo receives ferries from Lefkada. Public buses in Kefalonia are not that convenient, but there are buses to Argostoli and taxis every time a ferry arrives. There are also local ferries between Argostoli and Lixouri (every 30 min).
Arriving at the airport
The airport is located 6 km from Argostoli and it receives domestic and charter flights. There is a public bus to Argostoli and taxis every time a plane arrives.
The majority of the road network in Kefalonia is asphalt. However, due to the mountainous landscape, the roads are winding and narrow (one line per direction).
