A picturesque village located near a beautiful sandy beach. There are indications from findings which date the emergence of habitation in the 14th Century. Tradition has it that Tristinika used to be crossed by a river which supplied sufficient water to power a water-powered workshop for processing wool garments. Tristinika is a nickname and means small well; while others hold that the village was the grounds for a battle where the invaders were three times as many as the villagers-defenders and thus, for the defenders to win they each had to kill at least three enemies (in Greek treis=three and nika=win).
