Getting to Hydra from Athens: Ferry, Hydrofoil, and Day Trips
Getting to Hydra is straightforward once you understand the Piraeus ferry system. There are no flights and no road access — the island is car-free, so everything arrives by sea. The main route is the Flying Dolphin hydrofoil from Piraeus, Athens’ main port, taking approximately 1 hour 40 minutes each way. Prices below are approximate as of 2026.
The Flying Dolphin Hydrofoil (Recommended)
The Flying Dolphin is the hydrofoil service operated primarily by Hellenic Seaways on the Saronic Gulf routes. On the Hydra route, the service departs from Gate E8 or E9 at Piraeus Port and stops at Poros before reaching Hydra (approximately 1 hour 40 minutes total from Piraeus to Hydra). Some services continue to Spetses and Porto Heli.
Journey time: Approximately 1 hour 40 minutes from Piraeus.
Cost: Approximately €30–35 each way as of 2026. Return tickets can sometimes be booked at a slight saving.
Departures: Multiple departures daily in summer — typically every 1–2 hours from early morning to late afternoon, with the exact schedule varying by season. The first departure from Piraeus is usually around 7:00–7:30am. The last return from Hydra to Piraeus is typically around 7:00–8:00pm in peak season.
Booking: Tickets can be purchased at the Piraeus port ticket offices (in the terminal building near Gate E8) on the day, or booked in advance online through Hellenic Seaways or Ferryhopper. In July and August, popular morning departures sell out — book at least a day or two ahead.
Important: The hydrofoils do not run in rough seas. The Saronic Gulf is generally calmer than the Aegean, and cancellations are rare, but if there is a strong south or southwest wind (particularly from October onwards), services can be suspended. Check the day before travelling in shoulder season.
Getting from Athens to Piraeus Port
By Metro: Metro Line 1 (the green line) runs from central Athens to Piraeus station. The journey takes approximately 25–30 minutes from Monastiraki, 30–35 minutes from Syntagma. Take the metro to the Piraeus terminal station (the end of Line 1), then walk approximately 10 minutes to Gate E8/E9 following signs for Argo-Saronic ferries. Allow 45–60 minutes total from central Athens to your ferry gate.
By Taxi/Rideshare: A taxi from central Athens to Piraeus port costs approximately €20–30 depending on traffic. Journey time is 20–40 minutes, longer in morning rush hour (7–9am). Rideshare apps (Bolt, Uber) also operate this route. This option is useful if you have luggage or an early departure.
By Bus: Express bus X80 runs from Athens Airport to Piraeus port directly, taking approximately 60–90 minutes depending on traffic — useful if arriving from the airport and heading straight to Hydra without going into Athens first.
Parking at Piraeus: If arriving by car, the port area has paid car parks adjacent to the passenger terminals. Approximately €5–8/day for short-term parking. Do not leave valuables in vehicles.
Allow extra time: The Piraeus port is large and signs are not always clear. Allow 15–20 minutes to navigate from the metro station or the taxi drop-off point to the correct gate. Gate E8/E9 is well-signed for Saronic Islands; follow signs for “Argo-Saronic” or “Hydrofoil”.
The Conventional Ferry (Budget Option)
A slower conventional ferry also operates from Piraeus to Hydra, taking approximately 3.5 hours and costing approximately €15–20 each way. The ferry is less frequent than the hydrofoil and is more suited to passengers transporting goods or who prefer a slower crossing. For most visitors, the extra 1.5–2 hours each way makes this impractical for day trips.
The ferry service is operated by Saronic Ferries and departs from the same gate area as the hydrofoils. Check the schedule at Piraeus port ticket offices.
Guided Day Trips from Athens (Easiest Option)
Several Athens-based operators run guided day trips to Hydra, typically as part of a three-island itinerary combining Hydra with Poros and Aegina. These depart from marinas in central Athens (usually Marina Zea or Marina Floisvos, both accessible by taxi from the city centre) rather than Piraeus port, and include transport and a guide.
Typical itinerary: Depart Athens marina at approximately 8am, visit Aegina (temple of Aphaia, pistachios), stop at Poros, arrive at Hydra for free time and lunch, return to Athens by approximately 7–8pm.
Cost: Approximately €60–90 per person, often including the boat ticket, a guide, and sometimes lunch or drinks on board. Check what is included before booking — some are basic transport; others include meals and guided time at each island.
Booking: Athens-based guided day trips to Hydra are bookable through GetYourGuide or directly with operators at the Athens marinas. Browse Athens to Hydra day trips.
Trade-offs: The three-island combination gives you only 2–3 hours on Hydra (compared to a full day on the independent hydrofoil). If Hydra is the main destination, take the independent hydrofoil and spend the full day there. If you want an easy overview of multiple Saronic islands without planning, the guided boat trip is convenient.
Arriving at Hydra Harbour
The hydrofoil docks directly at the main harbour in Hydra Town — you disembark onto the quayside and are immediately at the centre of the island. No buses, no taxis, no transfer needed. Hotels coordinate luggage collection from the dock by donkey.
The ticket office for return journeys is in a small building on the harbour front (look for the Hellenic Seaways sign). Confirm your return departure time on arrival — schedules change seasonally and the last boat is not always at a time you’d assume.
Water taxis operate from the harbour and can take you to swimming coves around the island — agree the price before boarding. Approximate prices: Kamini €5–8 one-way, Vlychos €8–12 one-way, Bisti €15–20 one-way.
Combining Hydra with Other Saronic Islands
Hydra sits on the main Piraeus–Spetses ferry route, making it easy to combine with:
Poros: 20–30 minutes by hydrofoil from Hydra, approximately €10–15 one-way. A larger island with good beaches and a pine-covered hill town. Worth a night if you want variety.
Aegina: On the return route closer to Piraeus, approximately 40 minutes from Piraeus. Best known for the Temple of Aphaia and its pistachios. Can be added as an Athens day trip on a separate day.
Spetses: 30–40 minutes further from Hydra (away from Athens). Also car-free, more beach-oriented than Hydra. A logical next stop if you’re island-hopping south.
The hydrofoil ticket office at Piraeus (and the Hellenic Seaways website) sells island-hopping combinations. You can book one-way tickets between islands to build a multi-stop route rather than returning to Piraeus between each island.

Frequently Asked Questions
- How long does the ferry from Athens to Hydra take?
- The Flying Dolphin hydrofoil from Piraeus takes approximately 1 hour 40 minutes. The conventional (slower) ferry takes approximately 3.5 hours. There is no fast catamaran service direct to Hydra — the Flying Dolphin is the fastest option. Most services stop at Poros before reaching Hydra; some continue to Spetses and Porto Heli.
- How much does the ferry to Hydra cost?
- Flying Dolphin from Piraeus to Hydra costs approximately €30–35 each way as of 2026. The slower conventional ferry costs approximately €15–20 each way. Prices vary slightly by season and how far in advance you book. Hellenic Seaways operates the main hydrofoil service; book at the port ticket office or online in advance during summer.
- Is Hydra a good day trip from Athens?
- Yes — 1 hour 40 minutes each way means you can depart Piraeus at 7am and be on the island by 9am, with a return hydrofoil at 5 or 6pm giving you a full 7–8 hours. That's enough to walk the harbour, swim at Kamini or Vlychos, have lunch, and browse the galleries. If you want to hike to Profitis Elias monastery, the full round trip is 3–4 hours — still doable as a day trip if you're fit and start early.
- Can you take a car to Hydra?
- No — Hydra is car-free. There is no car ferry service because there are no roads or parking for private vehicles on the island. Leave your car at the Piraeus port car park (approximately €5–8/day) or at a hotel in Athens.
