Getting to Hydra Island Greece - Fly to Athens International Airport (AIA), transfer from AIA to Piraeus sea port by car taxi, express bus or train. Take Hellenic Seaways hydrofoil (dolphin or cat) from Piraeus to Hydra.
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.
HYDRA DOES NOT HAVE AN AIRPORT - NOT EVEN A LITTLE ONE!
Alternatively, you can take a car taxi from AIA or anywhere on mainland Greece and drive cross country to Metochi, which is right on the beach looking out at Hydra. There is a secure car park at Metochi for short or long stay parking. Then call a Hydra water taxi or use the reliable and regular passenger ferries, Hydra Lines (Freedom I, II, III & IV) or Hydra Celebrity (Metoxi Express) to reach the island.
Motorized vehicles are banned on the ENTIRE island - so you WON'T FIND ANY CARS on Hydra. Foot-power is the primary means of getting about on the island!
To get your luggage from the port to your accommodation when you arrive in Hydra:
