Tertsa is a small village located 91km south of Iraklion and 54km southwest of Agios Nikolaos, situated in the green valley shaped by the river Tsounas. Near the village is the Byzantine church of St. George.
In front of the small settlement there is a quiet beach with coarse gray sand, blue crystal clear waters, usually calm and with normal depth. In front of the settlement, there are some tamarisk trees offering natural shade. On the west end of the beach there is the rock of Psaroharako, with the homonym remote beach formed beyond this rock. This beach is more secluded and also nicer than this in front of the settlement.
