Thimonia is located in the southeastern part of Thassos between Alyki and the monastery of Archangel Michael. Its distance from Limenas is 32km and 16km from Poto.

It is a quiet rocky beach ideal for fishing. The beach is not organized, so it is suggested that you have the appropriate equipment. By the shore you will discover an ancient extant circular tower at an impressive height with an external diameter of 15m.
