Partheni - Temple of Artemis - Fakoudia
Start from the dam of Partheni and follow the sign to the archaeological place. You will reach it after ascending 400 m. It is not guarded, as there are only a few hewed stones coming from the sancturary of the Hellenistic period.
Continuing to the west, the path becomes steep and you will pass through a land with rush and carob trees. On your right, you can see the coasts of Partheni with the piers and the fishing boats.
The trail leads to a stone kiosk in the area Fakoudia, where you can visit the ruins of the battery Farinata. A few meters before the kiosk, there is a south detour (that has a length of 1km) leading to the top of Markelos.
