Flights & getting there
High-speed Hellenic Seaways (www.hsw.gr) ferries link Hydra with Poros, Piraeus and Spetses, and Ermioni and Porto Heli on the Peloponnese. Service is greatly reduced in winter. Buy tickets from Hydreoniki Travel, up the lane to the right of the Alpha Bank in Hydra Town.
Freedom boats run between Hydra and Metohi (little more than a car park) on the mainland (€6.50, 15 minutes, five to 11 daily). The schedule is posted on the quay and online.
