Kastos is an elongated small island in the Ionian group of islands. It lies southeast of the island of Lefkas / Lefkada, just below the island of Kalamos, and is separated from that island by a deep channel. Mainland Greece is about 5 kilometers away. From the small town of Mytikas on the mainland there are regular daily connections by caique (traditional wooden boat) with the island of Kastos. From the village of Nidri on the island of Lefkas there are also organized trips to the island Kalamos and Kastos.
The island of Kastos is almost 6 km2 in size, 7 kilometers long and 800 meters wide. The highest point on the island is 142 meters (in comparison, the highest point on the island of Kalamos just above Kastos is 754 meters). There are approximately 120 people living on the island that are primarily engaged in the tourism and fishing industry. All the people live in the only village of the island, which has the same name: Kastos. It is situated on the east side of the island and it is known as a good and safe harbor.
Kastos has low hills that are covered with olive trees, some of which are hundreds of years old. There are only a few roads on the island and the island is car free. Everyone here has a boat or makes the short distances on the island on foot. There are good and plenty of paths on Kastos and because the island is not to high it is an excellent walking-island. At Vigla there are remains of buildings from ancient times.
