You push off from Platis Gialos and the island chain slides behind you: a low horizon of scrub and white roofs, a warm wind pushing the bow toward open blue.

Operated by A La Mer · Platis Gialos (Sifnos), South Aegean
You push off from Platis Gialos and the island chain slides behind you: a low horizon of scrub and white roofs, a warm wind pushing the bow toward open blue.
After about eight nautical miles the boat eases into an archipelago that feels deliberately wild — Poliegos is uninhabited except for its goats, a scatter of limestone bluffs and a lighthouse that has watched the Aegean since 1898. Volcanic cliffs and pale pebbled coves alternate with hidden caves where the water turns an impossible turquoise; the boat slips in and out of narrow mouths so you can stare at mineral-streaked walls and swim among clear, cool currents.
Geology here reads like a field guide: eroded schist and marble meet volcanic intrusions, creating steep cliffs and small sheltered bays such as Faros and Kalogeroi. Cultural notes are quiet — the lighthouse, old mine ruins and faint evidence of shepherding recall a maritime past rather than permanent settlement. Wildlife is visible and undemanding: wild goats browse near small freshwater pools, gulls and shearwaters quarter the sky, and dolphins sometimes follow the boat’s wake.
Practical side: expect calm, warm water ideal for snorkeling; the operator supplies snorkel gear and bottled water. Wear reef-friendly sunscreen, a hat and water shoes for rocky landings. Check wind forecasts before heading out; Meltemi winds can make crossings choppy from mid-summer onward. The four-hour private format gives flexibility to swim in secluded coves, explore sea caves by tender, and time photos of the lighthouse without the push of a crowd.
