As well as sea views, THE KALLONI BAY HOTEL overlooks "Kalloni Pool", a small bird sanctuary (Natura 2000) were the constant comings and goings of birds in spring and autumn provide a visual delight. The Wetland of the Bay of Kalloni is one of the most significant parts of the ecological assets of Lesvos. The coastal areas that stretch perimetrically to the Bay of Kalloni consist a unified ecologic system, as this area is made up of of a mosaic of salt-pans, small river-estuaries, reedy-areas, pine-forests and olive groves. All these wetlands provide shelter, food and safety to numerous rare and protected species of migrant birds, as well as many that remain here to breed in the summer months.

The wetland areas have been placed among the European Program "Special Areas of Nature's Preservation" of the net NATURA 2000. Ornithologists from all over the world have come to appreciate the bird life on the island, particularly during the spring migration period. In spring the Kalloni pool, situated just in front of the hotel hosts an interesting variety of birds, including the secretive but highly vocal Cetti's Warbler to the sinuous Purple Heron, blending in with the tall vegetation. Looking beyond this small sanctuary, the skyline is dominated by the impressive 3000 feet high Mount Olympus in the distance. In the evening after dinner take a sundowner at the bar or by the pool or stroll through the vibrant Skala Kalloni.
