In summer many tourists visit Kefalonia, however as one of the largest islands in Greece, it is well equipped to handle them.

780 square km's of virgin landscape, well known beaches, watersports, subterranean lakes, impressive caves, fir-clad mountain slopes, castles and isolated monasteries are what Kefalonia has to show to its visitors. The beautiful island is the largest and also the administrative centre of the Ionian Islands .

Almost every community in Kephallonia has an ending with -ata like Lourdata, Favata, Delaportata, etc. Argostoli, Lixouri, and non-ata ending names are an exception.
Off the North East coast is Ithaca, a island well known worldwide thanks to the Odyssey, an epic poem written by Homer. Odysseus was said by Homer to be the leader of the "Kefallinians", which is often offered as an explanation for why modern habitants of the islands are keen on travelling to other countries.

It has also been suggested that Kefalonia and Ithaca may have once been joined because Homer describes Ithaca as if it is much larger than it now is. Geographical data also suggests the islands may have once been connected, although research is still being done to prove this.

The island is home to two large monasteries. One is Aghia Panagia in Markopoulo to the southeast, and the other is on the road between Argostoli and Michata, on a small plain surrounded by mountains. This monastery has an avenue of about 200 trees lined from NW to SE with a circle in the middle.

A spectacular view of the Ionian Sea can be seen from west of Skála to north of Fiskárdo. Most of Eastern half of Paliki is an exception.
