Poliegos
An uninhabited island of turquoise bays, quarried rock and goats — most of it reachable only from the water.

Twenty minutes off the south of Sifnos lies the kind of place a boat exists for. Poliegos is uninhabited — a Natura 2000 reserve with no roads and no village, its volcanic rock once quarried for millstones. What's left is caverns at the waterline, bays the colour of mouthwash, and the goats the island is named for. A La Mer have run this short crossing from the marina below the house for thirty years.

Good to know
How long is the Poliegos trip?
Usually a half-day; A La Mer confirm timing and route when you book. The crossing from Platis Gialos is short.
Can you swim and snorkel at Poliegos?
Yes — the bays are among the clearest in the Cyclades, with calm water around the rocks for snorkelling.
