By Flying Dophin or Cat

After you arrive at Piraeus either by bus or taxi, you will catch a flying dolphin (hydrofoil) or cat (catamaran) to Hydra. The trip takes about 2 hours.

Two companies, Hellenic Seaways and Hellas Speed Cat, provide service to Hydra. You can book online a their websites.

Contact Hellenic Seaways here.

The Hellenic Seaways schedule is posted here, although you won’t be able to purchase tickets until about one month prior to your travel dates.

Most boats will stop first at the island of Poros after about an hour and fifteen to thirty minutes. The boat will arrive in Hydra about half an hour later, then continue on to either Ermioni or Spetses.

Those traveling with heavy or awkward luggage may find it most convenient to  try to book a reservation on a flying cat. These larger catamaran-style boats are far more spacious, and boarding and debarking are much easier. Getting on and off the flying dophins can be a little more challenging. Travel on the cats also tends to be more comfortable, and both a business class and food and beverage service are available (not available on dolphins).

Boats run three to four times a day for each company during the busy summer months; during the off-season, they typically run twice per day.

Reservations are highly recommended in the summer months, particularly for weekend travel. Many Athenians have weekend homes on Hydra, so boats on Friday and Saturday tend to fill up quickly. The same holds for return boats to Piraeus from Hydra on Sundays and Mondays. If you can’t make your reservations via the website (likely because the seasonal schedule hasn’t yet been posted), you can try booking by phone.
