The small beach of Agia Irini is placed on the north east coast of Kythnos, in Loutra bay. It is a small typical sandy beach with pebbles and can be reached from the popular Loutra beach. The waters of Agia Irini are bright blue and provide a tranquil environment to relax, since it does not usually get crowded.

It is not one of the best choices for swimming in Kythnos, since Kythnos has many more beautiful beaches. It is more known for the very nice restaurant Aria that is located there (yoy may view more details about it at our Restaurants Directory). Agia Irini is also a good anchorage for many weathers.
