Atokos, is a small Greek island in the Ionian Sea and is one of the most westerly and perhaps remotest of the Echinades islands. It is situated 6 miles (9 kilometers) northeast of Ithaca and 5 miles (8 kilometers) southwest of Kastos. Atokos has two main bays, the One House Bay on the east coast and Cliff Bay on the south coast. The One House Bays is a preferred option for anchorage, as it safer for boats from the NW winds and has better access to the island via a pebbled beach and small flat hinterland. Atokos is a private island owned by the shipowner family of Panayiotis Tsakos. The tiny islet is uninhabited except for a few goats that roam freely around the island.
On the island there is the small chapel of St. John. This can be found by following a short path from the beach at One House Bay, and after the island`s well with the brackish water. There is also a two storey house belonging to the owner of the island and those two buildings are the only ones on Atokos. Visitors are allowed to go and swim in the beautiful beaches with the crystal-clear turquoise waters. To approach it requires a private boat. The seabed is very rich, ideal for snorkeling. Atokos is inside a Natura 2000 area.
