This geotrail, spanning approximately across 30 km, covers the Southwestern and Southern part of Thassos and for its most part follows the island’s circumferential paved road. This geotrail is accessible by car.

At approximately 1 km in the East of the village Skala Marion, there is a sign by the Archaeological Council, bearing the name “Fari” and leading to the excavations where the ancient pottery was unearthed. The visitor can stop near the fenced archaeological site by the sea and observe the first site of this geotrail which is of geological interest.
