Kastri is one of the most famous landmarks on the island of Kos and it stands out for its picturesque little church with the blue dome, dedicated to Saint Nicholas. It is located in the bay of Kefalos, right opposite the beach and the Basilica of Agios Stefanos. The islet is also called Paleokastro, as there used to be a Medieval fortification, remains of which are scattered throughout the islet.
It's easy to swim across and visit the island. The distance between the coast and the islet is approximately 90 meters. The first thing that someone does when reaching the island, it to ring the bell of the chapel. It is worth a trip around the islet to see its geological features, beautiful caves and if you are lucky, you might see some cormorants.
There is a small pier where boats moor. Just after there are formed steps leading to the small chapel. Kastri is considered one of the most popular parts of the island for weddings as it is isolated and has stunning views. The guests are transported to the island by boats from Kamari, the port of Kefalos. On the island there is also a beautiful, small beach. The islet is a reference point for all residents of Kos as well as for tourists.
