Hydra is not famous for its beaches, as they are small, pebbly and not easily accessible. In order to visit the best ones simply get a boat or a sea taxi.

• Vlychos (West Hydra): Vlychos Beach is a small, pebbly beach located a bit west of Hydra town. Access is possible by a 30-minute walk from the main town or by water taxi. There is not natural shade but there is a beach bar that offers umbrellas, sunbeds and refreshments. The boat ticket, including the return, is 8 euro.
• Plakes (West Hydra): Plakes Beach is a small pebble beach a bit west of Vlichos Beach, on the southwestern coast of Hydra. It is larger than Vlychos but it is laid with rocky pebble making it hard to walk barefoot. There is not natural shade but there is a hotel restaurant on the beach offering umbrellas and sunbeds.
