The beautiful bay of Koronaios is located between the peninsulas of Kassandris and Sithonia. It is known for its crystal clear waters and stunning views of the coasts of the two peninsulas.
Among them, there is an island of Halkidiki, which is called "Kelyfos". This island looks like a turtle and that is why it is called "turtle island" by the locals.
There you can enjoy your swim, swimming in the clear blue waters of Halkidiki.
