|The Prefecture of Kilkis is located among the prefectures of Thessaloniki, Serres, and Pella, spreading around the verdant plain of the Axios River - the earth's widest and most beautiful river, according to Homer.
There are traces of human presence in the region going back to the Copper and Iron Ages, while prehistoric settlements have provided significant finds dating back to the second millennium BC.
Among the natural beauties of Kilkis is the Doirani Lake, the Axios River, the mountain hills of Paeikos and Krousion, the natural waterfalls of Skra, the Mine Lake of Axioupolis, the Kilkis Cave, while the archaeological sites of Evropou, Palatianou and Gynaikokastrou are a challenge for a journey to the past. The museums one can visit are the Archaeological Museum of Kilkis, the Natural Museum of Axioupolis and the War Museum at Skra. Other sites of significant interest are all the churches -especially the ones dating back to the i8th and i9th centuries- as well as the monasteries and a plethora of monuments that pilgrims visit yearly.
Fully reconstructed economically and culturally, the region today gladly embraces visitors to its splendid areas endowed with unique natural beauty.
Capital Kilkis spreads out at the feet of a hill crowned by the post-Byzantine church of St. George with its unusual murals.
Lake Doirani in the northern part of the prefecture is one of the region's gems and a natural wonderland with idyllic hamlets built along its sandy shores, where local taverns serve a wide range of delicacies freshly fished from the lake.
South from the city of Kilkis, Lake Pikrolimni is an area of special tourist interest, featuring the Balkan's first organised mud-bathing therapy centre on its shores. Local people are creative, hardworking and very hospitable. They are mostly occupied in agriculture, animal husbandry, industry and increasingly with tourism.
Crops such as cereals, cotton, sugar-beet, tomatoes, superior quality wine, cherries, peaches, apples, walnuts and chestnuts are just some of the products of this blessed land.
Situated at a small distance from the northern Greek port-city of Thessaloniki, Kilkis has easy access to the international airport and harbour. A good road network provides for quick and comfortable travel from place to place. Due to its vicinity to other Balkan states and the border stations of Evzoni, Idomeni, Doirani and Koula - near Bulgaria - the region has been called the "northern gate of Greece".
