Tips for the Piraeus–Hydra Ferry
- If you have mobility issues, inform the ferry company in advance – assistance can be arranged for boarding and disembarkation at most major ports.
- Quick-dry travel towels pack much smaller than conventional towels and are worth the investment if you are covering multiple islands.
- A wide-brimmed hat provides better sun protection than a baseball cap on the open deck of a moving ferry, where the sun comes from multiple angles.
- Once you arrive in Hydra, you will find a car-free island with a picturesque stone-built harbour that has changed little in centuries. The island is best explored on foot or by donkey, with its neoclassical mansions, monasteries, and rocky swimming spots providing plenty to discover.
