Lake Kerkini.
It is part of the Aegean group.
The lake is known for its rich flora and fauna and is one of the top three bird watching sites in Europe.
It is a nature reserve and part of Natura 2000.
The lake has three accessible to visitors countries and three small dock.
The size of the lake varies depending on the seasons from 51.5 to 75 km2.
The lake reaches its maximum in late spring and early summer.
I visit it at least 2 times a year to observe and photograph the different birds that nest in it.
