Nea Potidea canal, which connects Toroneos Bay with the Gulf of Thermaikos, offers a view over the bridge so transfixing that compels visitors to stop and enjoy it even briefly. Visitors are frequently overcome by the feeling that the Kassandra peninsula is essentially an island whose “gates” are guarded by the picturesque town of Nea Potidea. It is no coincidence that this city, which has played a sovereign role in the area since ancient years due to its location, is known as the ‘Doors of Kassandra’.
