Melissani Cave in Kefalonia (Greece)

Visit the Melissani Cave in Greece

The Melissani Cave is located on the east coast of the island of Kefalonia in Greece. It is located about 2 km from the town of Sami and 5 km from the town of Agia Effimia. The cavity, which contains a lake, is surrounded by the forest and a mountain slope to the west. Below you will find pictures of this magical place with additional information about the history of the cave and the best time to visit it and what you can expect to see.


The water of the lake is brackish (water with a salt content significantly lower than that of the sea), it is a mixture of sea water and fresh water. The cave is located about 500 meters from the sea. The water has a maximum depth of 30 m and the water level is 36 m at the bottom of the cave. On one side the lake is open, on the other side it is illuminated by electricity.

The best time to visit the cave is in the middle of a sunny day. Boats will show you the two parts of the cave separated by an island. The cave looks strangely similar to the cenotes of Mexico.

In Greek mythology, Melissani was the cave of the nymphs.


The cave is much visited by tourists and it is a pity because you can only stay in the cave for about ten minutes after paying a lot of money. You can also take a longer guided tour with a diving school. You can observe the cave from above thanks to a balcony that has been built for this purpose.
