From Bogdanatika, by the road that runs beside the church of Agia Paraskevi, a narrow but easy path sets off westwards. It is short and pleasant walking.
It passes first between drystone walls and the yards of old houses and newer villas, then out into the olive groves, and as it climbs the soil gives way to bare limestone. Part way along, set back from the path, stands the well of Ostria: a stone arch in the drystone wall, steps going down to the water, and a long carved trough that was the wash house of the hamlet.
The path ends on the cliff edge, with the Ostries opening in front of you: the beach of Avlaki below and the bay of Agrilas beyond. It is one of the sunset places the islanders name first.
At the edge itself, beside the view, stands a second water work: a low well house, built like a little cottage, its mouth guarded by an iron cage and the paving around it laid to gather the rain. Ostria had water at every step of the way.
The Ostries are also a station of the Paxiot Easter: the icons of Agios Charalambos and of the Eleousa rest at Agia Paraskevi, at the start of this path, until the Sunday of Thomas.
Take care at the edge, which is unfenced.
