Piraeus to Hydra by sea
Athens Piraeus boat Hydra
Hydra is a car-free island in the Saronic Gulf, reached from Piraeus — Athens' port at the end of Metro Line 1 — by fast passenger boats that leave from Gate E8 (Aero catamarans from Gate E9). There is no car ferry to Hydra: every boat is a passenger-only craft (Flying Dolphin hydrofoils, the Magic 1 catamaran and Alpha Lines' high-speed ferry). This site puts the Athens-to-Piraeus links, the gate, the three operators and the first steps on Hydra in one place, from official sources only.
