All about the tour to Marathonisi and Keri Caves


The islet of Marathonisi in Laganas Bay, known as “Turtle Island” for its characteristic shape and because it is a vital breeding ground for sea turtles, is one of the lesser-known of the many attractions of the Ionian Sea.The islet, near the larger island of Zakynthos, is located just off Keri Beach, in Laganas Bay. Marathonisi also includes two, even tinier, islets, which are together called Pontikonisia..

Keri caves

Keri Caves are often also called Marathia Grottos, because they are located on the southern and south-western part of the Keri peninsula near the village of Marathia. Caves are inaccessible from the seashore and are closed in the cliffs, which can be accessed from the sea. Excursions to the caves are organized mainly from towns located in the southern part of the island (Laganas, Agios Sostis, Limni Keriou).
