Athens to Hydra Ferry: Times, Fast Boats and Wind Cancellations

Athens to Hydra ferry times and prices in 2026

Hellenic Seaways, Magic Sea Ferries and Alpha Lines run the route all year. Their timetables are published separately and change with the season, so the useful thing to know is how the three compare.

In summer the first boats leave Piraeus around 8 in the morning and sailings run through the day into the evening. A typical Magic Sea weekday in 2026 leaves Piraeus at 11:00 and reaches Hydra at about 12:20, then carries on to Spetses. The fare gap between companies is real: the lowest Hellenic Seaways fare, around €28.50, is ten euros under the others, while Magic Sea sells an economy seat with a table for €46 and has offered up to half off the return leg until October 2026. Check your own date rather than a schedule copied from an old blog post: the companies reissue their timetables every season.

Which boat goes to Hydra: Flying Dolphins and fast catamarans only

Some of the booking sites list Blue Star Ferries on this route. None of the operators' own schedules do. The car ferries on the Saronic line stop at Aegina and Poros. What reaches Hydra are passenger-only fast boats. The best known are the yellow and white Flying Dolphins of Hellenic Seaways, hydrofoils that lift out of the water on submerged wings once they reach speed. The same company runs the larger Aero catamarans, and Magic Sea Ferries and Alpha Lines each run their own high-speed craft.

No car ferry means no car on board, and on this route it costs you nothing: Hydra bans cars, scooters and even bicycles. What it does change is the ride. The Flying Dolphins have airline-style seats and no outside deck, so you see the gulf through a salt-streaked window and cannot step out for air. The catamarans are roomier and usually steadier in a swell. If you get seasick, choose a direct sailing on a catamaran, sit low and near the middle, and avoid the last boat on a windy afternoon.

Booking the Hydra ferry: how far ahead, and the Sunday problem

The boats are small, and Athenians use Hydra as a weekend island. A midweek seat in June or September is easy to find a week or two out. Friday departures and Sunday evening returns sell out weeks ahead in summer, and on public holiday weekends the Sunday boats go first. Book the return at the same time as the outbound, on a boat that leaves you a margin before any flight. E-tickets are the norm now: you board with the ticket on your phone, with no paper to collect at a kiosk.

Piraeus to Hydra: finding gate E8

The Hydra boats leave from gate E8, on the stretch of Piraeus nearest the metro station. Hellenic Seaways and most booking sites agree on it. One guide says E10, and nobody else does. From the station at the end of line 1 it is about a ten-minute walk. Line 3 runs to the same station from the airport and through Syntagma and Monastiraki, as the map of Athens shows, and the ride from the centre takes about half an hour.

Aim to be at the gate about an hour before departure. The fast boats load quickly and leave on time, and a boat you watch pull away from E8 is a boat you rebook at full price. Gates occasionally change on the day, so read the one on your ticket and check the boards before you settle down with a coffee.

Hydra ferry cancelled by wind: how often, and what happens

The decision is not the company's. The Hellenic Coast Guard, through the local port authority, bans sailings when the wind gets up, and it bans them class by class. Fast boats go first. The Greek press puts the usual cut-off for high-speed craft at around force 6 to 7 on the Beaufort scale, while the big conventional ferries keep sailing at their captains' discretion. Aegina and Poros keep a car ferry when that happens. Hydra has none, so a ban on the fast boats cuts the island off from Piraeus until it is lifted.

Two things surprise people. The first is that the famous summer wind, the meltemi, hits the Cyclades much harder than the Saronic Gulf. On 14 August 2026, with the meltemi at force 9, sailings were banned from Rafina and Lavrio and several Cyclades boats out of Piraeus were cancelled, while the Saronic lines ran normally. The second is spring. On 25 and 27 March and 1 April 2026, the morning Flying Cat 3 from Piraeus to Poros, Hydra and Spetses was cancelled for weather, and an Aero 2 sailing went the same way. On this route, the off-season gales can do more damage than the summer wind.

Cancellations are announced on the operators' sites and passed on by text or email to the contact details on the booking. If the port authority keeps your boat in port, the company must put you on another sailing at no extra cost or refund you in full. EU passenger rules exclude compensation for weather, so a refund is all you get. The practical rule: do not put the Hydra boat and a flight home on the same day, and keep one night in Athens as a buffer.

Plan B when the Hydra boats stop: the crossing from Metochi

Hydra lies a short way off the Peloponnese coast, and a small passenger boat crosses from Metochi on the mainland in about 20 minutes. The fare is €7.50 one way or €14 return, €4 for children aged 5 to 10. It runs all year with at least two crossings a day, you cannot book, and you turn up 15 minutes before it leaves. There is secure parking on the Metochi side.

This is the back door, not a guaranteed exit. It sails only when the weather allows, and getting to Metochi from Athens means a long drive round through the Peloponnese, several hours rather than one. It earns its place in two situations: when a gale has cleared but the Piraeus boats are sold out, and when you have a rental car and want to fold Hydra into a road trip. Water taxis also cross from Metochi, for much more money, split between up to eight people. The other islands of the gulf, and the short crossings to Poros and Spetses from the same coast, are set out in our guide to the Saronic islands.

Athens to Hydra day trip, or a night on the island

A day trip on the scheduled boats works. Take a morning sailing, land before eleven, and come back on an evening boat: you get most of a day on the island for two fares of about €30 to €40 each, and the crossing is short enough to leave you some energy for the walk up to the monastery above town. It is the better option than the organised three-island cruise from Faliro, which gives you about an hour and a half on Hydra.

Hydra is still the island most people wish they had slept on. Once the cruise boats and the day-trippers leave, the harbour becomes a different place, and a night takes the pressure off the last boat on a windy day. The town is small, but where you stay decides how many steps you climb with your bags, which is why our Hydra hotels guide counts them from the quay. Midweek rooms are cheaper and the Sunday boat back is not your problem.

Arriving at Hydra port: no cars, mules and water taxis

All the boats from Piraeus dock in the main harbour, in the middle of Hydra town. There is no bus and no taxi rank, because there is no road. Muleteers wait on the quay and charge by zone, about €10 a mule for the lower town and €20 for the upper town, and most hotels will send a porter to meet the boat if you tell them which one you are on. Water taxis leave from the same harbour for the coves and beaches along the coast. Bring a bag you can carry up stairs, because even with a mule you walk the same lanes yourself. The mule and porter prices are listed zone by zone with the hotels.

Hydra to Athens: the boat back

The return runs the same way in reverse, from the same quay, on the same three companies. Some return fares start lower than the outbound, from about €15 on certain sailings, and the Sunday evening boats are the ones that sell out first. From Piraeus you are one metro line from the airport and a few gates from the boats to the Cyclades, so Hydra fits well as the first or last stop of an island trip.
