DON'T PANIC: if you can't find a timetable for Hellenic Seaways or the passenger ferries from Metochi at this time of the year (January - March). It is simply that no one can publish times until the Greek Ministry approves the spring and summer timetables which happens at the end of March/April. Please be assured though that you will be able to book tickets and get to Hydra even if booking your dolphin ticket will be a last minute job! Regards Kelsey, 29 Jan 2017.
The port of Piraeus is large and sprawling. If you take a taxi from the airport, ask for Piraeus and make sure the driver knows you're heading for Hydra and then you'll get put down at the right part of the port. The bus terminal (as of 2013) is NOT right outside the port gates so you need to speak to the driver and make sure he understands that you want to be put down for the flying dolphin to Hydra at Piraeus. You will need to cross the main road which is very busy so please use the crossings at the lights.
Hellenic Seaways operate their hydrofoils (Flying Dolphins) and Catamarans (Cats - bigger than dolphins) out of Piraeus and have a regular timetable throughout the year. You'll find their ticket offices around the port. Don't forget to ask the ticket office to point out where you dolphin will leave from. YOU CAN BOOK ONLINE and take your reservation number (it will be emailed to you) to the ticket office to collect your ticket on the day of travel - make sure you leave yourself enough time in high season in case there's a queue.
Hellenic Seaways are one of the main carriers between the Greek islands and the mainland. They have a huge number of routes. Hydra is on the route that also includes Poros, Spetses, Porto Heli and Ermioni. What is included on the route depends on the time of day that the flying dolphin or cat leaves however Hydra is such a popular destination that it is included on most trips anyway.
Price range: Return trip from Piraeus to Hydra on flying cat approx. €54.00 (2015) per person.
