Lake Kerkini is situated in the northeast of the district of Serres, at just 40km distance from the town of Serres and 100km from the city of Thessaloniki. The lake is surrounded by mountains Belles and Mavrovouni, at close proximity with the Greek-Bulgarian borders. Lake Kerkini:Kerkini is an artificial lake that was created in 1932, and then redeveloped in 1980, on a site of what was previously an extensive marshland. It is now a wetland of great environmental significance as a result of man's technical intervention on the natural characteristics of Strymon River. Human intervention at the environment usually retracts or takes negative action against the natural processes but Kerkini Lake is a rare paradigm, where logical human handling had the exact opposite result. Nowadays the waters of the lake are mainly of agricultural utility while the lake and surrounding areas provides shelter to a series of wild life species.
