The farming land of Petra with its fertile valley had since the early years the advantage of being autonomous in the grinding of the grains it produced. The steady flow of the spring of Ligonas supplied with water a series of (17) mills, the towers of which bear witnesses to the pre-industrial past and they are monuments of the architectural heritage of the island. The Trail passes from the chapel of Saint Fotia (Saint Foteini) and climbs up through mill trenches by the ruins of the mills to the Ligonas ravine, a terrain of particular geomorphologic interest. After a visit to the spring and a climb to the old chapel of Saint Dimitrios in the Monastirelia region, the tour in this special valley is completed. Tiny Petri offers an uninterrupted view to the valley of Petra, the small islands and the open sea. Descending from the Achilleiopigada area, the trekking circle ends under the rock of Panagia on the square.
