Many of the rocks also contain fossils.
Sarakiniko got its name from the Saracen pirates who used the place as a base and shelter. You can still see the carved anchors from their ships amongst the rocks and the caves that they carved out of the soft rock at the bottom of the canyon at the mouth of its small sandy beach.
From Sarakiniko one can enjoy swimming in the sea with a view of the nearby islands Sifnos and Kimolos.
Papafraga
Blue-green waters between impressive white-grey rocks form the natural scenery of Papafraga that enchants all who visit.
The cavern of Papafraga is a deep sea cave, surrounded by high walls of light-coloured rocks, and to reach it you have to descend down via a steep carving in the rock wall.
During the Byzantine period, Papafraga was used as a launching pad for pirates, while it was named after the late Frank Pope who used the beach to protect his boat.
