Located in the coastal village of Possidi on the southwestern tip of the Kassandra Peninsula, Possidi Beach is a large and wide beige sand beach with many rocky portions. The beach is positioned on the shores of the Thermaic Gulf and has a beautiful backdrop of Possidi Lighthouse, cliffs, protected dunes, coastal vegetation, and several oceanfront buildings adding allure to its beauty, which together provide incredible views of Mount Olympus and the Aegean Sea. Possidi Beach has an iconic sandbar, popularly known as Possidi Cape, which stretches into the sea and changes shape depending on the sea current. In addition, there are ruins of the ancient city of Mende, positioned on the eastern end of the beach, famous for its sanctuary of Poseidon, which served as a place of worship for over a thousand years.
