To the east of the Kalloni bay, near the settlement of Vasilika, is the impressive Pessa waterfall.
The waterfall is created due to faults that affect the ophiolitic rocks of the area, as well as the smooth flow of the “Makris” stream, which originates from the northwestern foothills of Mount Olympus, creating intense terraces in the relief. The waters of the waterfall fall with a rush, from a cliff about 15 meters high. Due to the momentum of the water, during the fall, a vortex is created in the flow, resulting in the deepening of the bed and the creation of a natural pond.
Then the water continues its course towards the bay of Kalloni, where it empties, near the beach of Agios Pavlos.
