North-west of the Kalloni bay between the settlements of Anemoti and Parakoila, is the Potamia waterfall, impressive in beauty.
Its waters originate from the mountainous massif of Prophet Ilias (799m.), on whose slopes grows the unique black pine forest. Among the dense black pine forest, the unique in Greece, but also in Europe, riverside plant communities with rhododendron (Rhododendron Luteum) thrive, as well as peonies (Paeonia mascula) (Peonia the Romalea) and the large fern called “Osmunda the basilisk” (Osmunda regalis).
The waterfall is created due to the discontinuities of the volcanic rocks that are affected by the faults in the area and shift the bed of the stream. The stream of Potamia continues its course and empties into the gulf of Kalloni.
