Kastos is a small island southeast of Lefkada, very close to Mytikas of Aetoacarnania, the port from which you can access the island.
The single settlement of the island is located on the east side and has stone houses and small taverns around the port. It is a green clad island with many olive trees and vineyards. On the east coast there are beautiful beaches such as Ampelakia, Vali, Kilada, Limni, Kamini, Vrisidi and Agios Emilianos, where Fokotrypa (Seal Hole) is located, a small cave with a beach inside it. On the south side there is the beach Fyki.
Its west coast is very steep and only the bay of Sarakiniko, with a small pier, can be used as a shelter for boats.
The main products of the island are cereals, grapes and wine.
Although Kastos is a rather small island it has interesting sites such as the temple of Agios Ioannis Prodromos, which was built in the 19th century, with oil paintings of Spyridon Gazis, the chapel of Agios Emilianos and the olive grove with century old olive trees in Kalikerimi. Furthermore, there are old olive mills and many windmills on the island. One of the windmills is the best preserved in the Ionian Islands with all its apparatuses intact. It had been functioning until 1949.
Archaeological findings from the Post-Hellenistic, Roman and Early Byzantine years have been discover on the island. Like Kalamos, Kastos was also a refuge for both fighters and civilians during the Greek Revolution.
In Kastos there is the Marine Museum “Home of the fin whale”.
