The Sousaki is a dormant volcano located at the southern ends of Geraneia mountains in the Agioi Theodoroi district. Sousaki volcano is the Northwestern part of the active volcanic arc of the Aegean. In spite of its continuous sleep through the ages, the volcano still emits sultry fumes.
You can reach the area by crossing a short, rough path among olive trees. The scenery looks almost lunar, the air smells sulphur, whereas the sloping volcano is full of impressive stones.
In the ancient years, according to Xenofontas, in the same plain area, there used to be the coastal settlement of Sidous, which was widely known for its apple trees.
