According to the Zwerger map there are three small lakes on the pensinula. One is situated near the old Roussikon or Paleo Monastiro. The second one is near Ag. Dimitriou or Demetrius above Simonos Petras and the third one is underneath the mountain of Antithonas at a region called Gravanudes. I did not found a picture of this lake. Who has one?
