Flanked by reeds with water-lilies opening their blooms to the sun, this Natura 2000 artificial lake – which rises or falls by 4.5 meters depending on the season – is a must-see for the thousands of birds that gather and reproduce here (see birdwatching section). Sightseeing boats leave from the ports of Mandraki and Kerkini while numerous other activities are available. Visit the Office for the Promotion of Ecotourism which has been in operation since 2002 in the village of Lithotopos.
