Almost all life on Hydra is in one harbour town, and it rises around the harbour in a horseshoe of grey-stone houses stacked up the slope like seats in a theatre.

The port is the island. There is no second town competing for your attention - beyond it are a few small coastal hamlets, and behind it bare hills, monasteries and walking paths.
The vehicle ban is real, and it is broader than you think
Private cars, motorbikes and scooters are all banned, and so are bicycles.
That last one surprises people. This is not a pedestrianised centre with a car park behind it - it is an island with no wheeled traffic on it.
Transport is on foot, by donkey, mule or horse, and by water taxi.
The ban is imposed and policed by the authorities rather than left to local custom, and it has held for decades. That is why Hydra is not a town that happens to be quiet: it is a town built around the absence of engines, and the sound of the place is the thing visitors remember.
What that means for arriving
Plan the luggage. Everything that comes off the boat moves by hand, by animal or by water, including yours, and the houses are stacked up a slope.
If you are staying above the harbour, that is a climb with bags at the end of a ferry journey - worth knowing before you book the room with the view.
Getting there
There is no airport. Arrival is by ferry, and the Piraeus route is served only by fast boats, about 1 hr 5 min to 1 hr 30 direct.
It is also reachable via the Peloponnese ports - Ermioni, Porto Heli, Metochi - and the neighbouring Saronic islands, Poros and Spetses. The Saronic route covers doing more than one.
Swimming
Swimming is off rocks, which is the honest description of this island’s coast. The Hydra beaches guide covers where, including Vlychos.
If you are picturing a sandy bay, this is not that island - and the harbour town is the reason to come regardless.
Practical notes
Hydra is one of the four Saronic islands that matter, and the group’s whole value is proximity: the only Greek islands you can genuinely visit on a day trip from Athens.
Hydra in particular rewards the night, because the day boats leave and the harbour becomes itself again.
Common questions
Are bicycles really banned? Yes - along with cars, motorbikes and scooters. The ban is policed.
How do I move my luggage? On foot, by animal, or by water taxi. There is no other option.
Can I do it as a day trip from Athens? Yes, and many do. Staying the night is a different island.
