Hydra is one of the few Greek islands that genuinely lives up to its reputation, and the Piraeus to Hydra ferry is how most travellers get there. Just under two hours across the Saronic Gulf, this is a straightforward crossing with year-round service — so whether you are planning a summer escape or an off-season visit, you have options. If you haven't sailed from Piraeus before, our Piraeus ferry port guide covers the gate system and how to get to the port.
On average, eight ferries a day run this route across the year. Peak summer (June–August) sees up to 11 departures daily, giving you plenty of flexibility. Come winter, frequency drops to around four sailings a day, so a little planning goes a long way.
