The sea-route of Ithaca starts from the capital of the island Vathi and we head towards Northeast to the geosite of Sarakiniko passing on our way in front of the Dexa and Skinos bay, as well as from the Geosites Gidaki and Filiatro where we can admire the intense geomorphology of the bays which were formed from the eustatic movements of the sea during the last glacial periods. Also following this sea route we can see almost the whole lithological sequence of the Ionian zone that occurs on the island of Ithaca. Then we head towards to the geosite Atokos, sailing around of the island in order to see here the special geomorphology as well as the similarity of the lithological formations with those of Ithaca, the sequence of which appears reversed. Then we return to Ithaca and specifically to the northern part of the island where we first pass close to the second largest settlement of the island, the picturesque Kioni and then we head towards the geosite of Marmakas, which is located outside of the port of the village Frikes. Except for the beach and the small coastal swamp consisting the only wetland of the island, it is a landscape in which we see the occurrence of three different rock formations of the Ionian zone, the limestones of the "Pantocrator", the formation of Ammonitico Rosso and the limestones with cherts and clay shales. Then we head towards the geosite Afales where we have the opportunity to see the Paleocene-Eocene limestones as well as the flysch formation (alternations of sand and clay layers) of the Ionian zone. We continue the geroute heading towards to the Arkoudi islet where at the major part occur the limestones of the "Pantocrator" and at western part we can observe Triassic breccia. Finally we head towards the island of Kefalonia and specifically to the port of Sami crossing the "strait" of Ithaca along which we see at the same time the island of Ithaca and the northern part of the island of Kefalonia.
