Herronisos is the northern cape of Sifnos . A narrow band of land connects the cape with the main island. In the western side of the cape , the gulf of Herronisos is shaped. The entrance of the gulf provides physical protection and a safe anchorage, for the boats, during all the weathers. In Herronisos you can find a little graphic fishermen village, a few graphic taverns next to the sea and a beautiful sandy beach with crystal clear waters, ideal for families with children.
The small rocky coast of Epta Martyres (“seven martyrs” in Greek) is situated just below Kastro, a bit northern to the village, in front of the homonymous country church, at a distance of 4 kilometers eastern to Apollonia. Access from Kastro is possible on foot, stepping down the stairs leading down to the sea; you will follow the signs indicating “Epta Martyres”.
