This incredible marsh lies in the northernmost section of the prefecture and spills into part of neighbouring Ioannina region as well. Despite the fact that it occupies a space between 100 -150 meters (depending on which season it is) the Kalodiki Marsh is an invaluable ecosystem with over 300 types of plants, 120 species of birds, 20 different mammals, 11 reptiles, 5 kinds of amphibians and several fish species. Kalodiki Marsh is part of the Natura 2000 initiative designed to protect such important ecological environments. The marsh presents an excellent stage for bird watching in an area that contains undeniable beauty. Observers have the opportunity of witnessing Night Herons, Black Herons, Golden Eagles, Vultures, Little Grebes, wild ducks, turtle doves, blackbirds, magpies and starlings.
