The lake is situated in the northeast of the district of Serres, at just 40km from the town of Serres and 100km from Thessaloniki, and it is surrounded by Mounts Belles and Mavrovouni. Its unique wetland has been declared as National Park according to Ramsar Convention and it is one out of ten wetlands of International Importance of Greece. The lake is a rare example of fine human intervention in a superb natural landscape: the delicate balance of the ecosystem has been preserved to offer great benefits to the region. The lake offers the ideal conditions for bird watching. It is one of the best places in Europe for natural watching of about 300 rare and protected bird species that live and breed here.
