Halkidiki is a three-pronged peninsula located south of the city of Thessaloniki. It comprises of three smaller peninsulas Kassandra, Sithonia and Athos. These three “fingers” give Halkidiki a uniquely winding shape, as well the longest stretch of coastline, approximately 550 km, than any other mainland prefecture in Greece.
