Tips for the Santorini–Ios Ferry
- Travelling in May or June gives you considerably more choice and flexibility when island-hopping – spontaneous decisions about your next destination are genuinely possible in ways that simply aren’t realistic in August.
- If the sea is choppy, fix your gaze on the horizon, breathe steadily, and avoid looking at your phone or a book. Fresh air on deck helps considerably.
- The quietest months are November through February. On some crossings you may find you have the ferry almost entirely to yourself – a striking contrast to the packed summer sailings.
- In Ios, the whitewashed Chora draws visitors with its narrow footpaths, windmills, and the climb to the Church of Panagia Gremiotissa for sweeping views across the Aegean. The island’s beaches are among the finest in the Cyclades – Mylopotas, Manganari, and Magganari are the most celebrated – while Homer’s reputed tomb lies on the northern hillside.
