Chalkidiki lies around 69 km southeast of the city of Thessaloniki, the second largest city of Greece. It is divided into three peninsulas Kassandra, Sithonia and Athos, which lay in the sunlight in the northern Aegean.
As a result of its shape and its close proximity of the sea, Chalkidiki has the longest coastline on mainland Greece. Its winding coastline is marked by four sizeable gulfs – the Thermaic Gulf to the west, the Gulf of Orfanou to the east as well as the Gulf of Toroni and the Mt Athos Gulf in the south. Low mountains are scattered throughout with Holomondas (1,165 m), Hortiatis (1,201 m) and Stratoniko (913 m) among the tallest peaks.
Chalkidiki enjoys a Mediterranean climate with a small number of sudden brief but refreshing downpours. In general, winters are mild and summers are dry.
The three “fingers” cover a landmass measuring 2,945 square kilometres and are home to a population of around 79,000 people. Its capital is called Polygiros and is located in the center of the peninsula. Chalkidiki offers numerous kinds of flora and fauna and provides the opportunity to the visitor to enjoy its 522 kilometers of natural beauty and overwhelming beaches. The purity of the crystal-clear waters is confirmed by the widespread presence of EU Blue Beach Flags (45 in 1998, the highest number in Greece). Every corner of Chalkidiki is a paradise on earth. Sunny, golden beaches, deep and picturesque gulfs, and many traditional villages compose the picture of modern Chalkidiki.
The beautiful crystal clear beaches and the well-organized areas attract thousands of tourists every year. The road system is continuously been developed and the entertainment that Chalkidiki offers is exceptional. The villages are gorgeous and traditional. The islands that surround it are many and beautiful. Men can visit the Agion Oros since it allows entrance only to men and enjoy the historical monasteries and beautiful landscapes. For those who love mountain climbing can enjoy Mount Cholomonta and for the fishermen out there, its best to check the weather since Chalkidiki is known for sudden climate changes. And for hunters, there is little game and is protected so it is best to pay a visit to the hunting associations of Arneas, Kassandrias and Neon Moudanion before starting out.
