LOCATION AND SIZE

The emerald island of the northern Aegean

Thassos, the twelfth largest Greek island, lies in the Thracian Sea, just 8 kilometres from the mainland. Its area of 380 km² offers a surprisingly varied landscape, from dramatic mountains to fertile lowlands and picturesque bays.

The island has an elliptical, almost regularly round shape, 22 km across from west to east and 26 km from north to south. Between the island and the headland of Keramoti bay lies the islet of Thasopoula, or little Thassos, which acts as a breakwater protecting the boats on the route to the mainland.

On foot from the village of Potamia, or in a 4×4 with an off-road permit – an ordinary hire car is not allowed on dirt roads.
