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.
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!
