Travel to Hydra


Hydra is a small island in the Argo Saronic Gulf, lying off the east coast of the Peloponnese and easily reached by modern catamarans (Flying Cats) from the Athens port of Piraeus. The entire island is a preserved national monument which has retained its unique architecture. There are no motorized vehicles, and transport from the main Hydra town to surrounding small villages is either on foot, by donkey or by water taxi. Nevertheless, the town has excellent modern amenities and retains a relaxed cosmopolitan air. The following websites provide detailed information on the island (travel directions, hotels, apartments, restaurants, activities etc):
Hydra town has a wide selection of restaurants and cafes, and the village of Kamini, a 20 minute walk along the coast to the west of the port, also has a number of nice restaurants. There are numerous places to swim within a short walk of the town on the west side, although these are from rocks or platforms. There are a number of sandy beaches in Mandraki (a 30 minute walk to the east of the port or reached by water taxi), Bisti bay and Aghios Nikolaos, both only accessible by water taxi. There are some excellent walks/hikes, although you will need to be very careful of the sun.



Athens International Airport “Eleftherios Venizelos” is situated on the east side of Athens about 1.5 hrs from the port of Piraeus, where you catch ferries for Hydra, so bear this in mind when planning your trip and allow time to clear immigration and get to the port. The latest information is on the airport website here: 

If you arrive too late to reach Piraeus, it is preferable to stay overnight in Athens. Piraeus is a port with limited attractions. However, if stuck, try the Lilia hotel

X96 Express Bus

The easiest way to get to Piraeus is by bus (X96 Express, previously designated E96), and we strongly recommend that you use this option. Leave the airport through exit door 5 (turn right after customs, the last door at the end of the arrival hall). Purchase a ticket from the booth before boarding the bus. Tickets currently (2023) cost 6 Euros per person. The X96 bus and the bus stop are clearly marked in English and Greek with the destination (Piraeus). There is plenty of space for luggage and they leave 2 or 3 times an hour, 24 hours a day. When you board please make sure you validate your ticket by scanning at the blue box by the door. There are on the spot fines if an inspector finds unvalidated tickets. The journey time takes about 1.5 hrs.  If you plan to visit Athens first, then a similar express bus (X95/E95) leaves the airport between exits 4 and 5. The journey takes 45-60 minutes and will be a similar price. 


There is a metro terminal right in front of the airport. The trip to Piraeus takes about 60 minutes and is 9 euros. Take line 3 from the airport, to reach Pireaus


The taxi rank is outside exit door 3. Yellow taxi prices vary depending upon the time of day, the number of passengers and the season, but you should budget for 50-60 Euros for a one-way trip to Piraeus.


The simplest way to get to Hydra is to take a catamaran ferry (Flying Cat) from Athens port (Piraeus) operated by Hellenic Seaways and Alpha Lines. Ferries for Hydra leave from gate E8, and the journey takes 1.5 – 2 hours.

It is advisable to book tickets online prior to your arrival as ferries can get booked up.  Ticket offices can also be found at Gate E8 at Piraeus port. 

Flying Cats leave at fairly regular intervals during the day from 8:30 am. On the day of the Conference (1 September) the Hellenic Seaways 17:30 departure is the latest that will arrive in time for the Keynote Lecture, and the last Flying Cat for Hydra leaves at 19:30 with Hellenic Seaways.  If you are arriving late, it may be best to stay overnight in Athens.  Please note that timetables can change at short notice so please be sure to check close to your date of travel.
