Greece's water experiences are foundational to the destination rather than supplementary. The island ferry network — the old Hellenic Seaways routes between Athens' Piraeus port and the Cyclades, Dodecanese, and Ionian islands — is itself a mode of Greek travel with its own rhythms and pleasures. Sailing holidays around the Cyclades, anchoring in small harbours at dusk and moving on the next morning, are what Greece does better than any other Mediterranean destination. Sunset catamaran cruises from Santorini's caldera, sea kayaking through the caves of Kefalonia's Melissani lagoon, and traditional caïque boat tours around the bays of Paxos each add specific pleasures. A hydrofoil to Hydra on a spring morning, when the car-free island is still quiet, is a water journey with an arrival that never disappoints.
