You will go for:
Its architecture. Her houses, cubes perfectly placed amphitheatrically above the harbor, as in the paintings of Hydraios Hatzikyriakos-Ghikas. Her flowery paths, which will fill two days (8-9 April) with athletes for the Hydra's Trail race (www.hydrastrail.gr). Run with them or cross them any time of spring you are there. Climb up to Prophet Ilias for a panoramic view of the settlement, on the slopes and in the sea.
Get to know its permanent residents. Hear stories about the difficulties and joys of everyday life p’ a very beautiful place, no cars or other motorized vehicles. With the donkeys - mules to be precise - lifting the whole island on their backs, giving a special picturesqueness.
Go sailing. Anchor in the lovely little harbor and head out to meet sailors coming from all over the world, with peak season in spring. Those of you who are more serious about the sport will already know the two major sailing races that are organized on the island during the year (in March and October). If, again, you'll want to make a good first dive early to discover the bottom of the Hydra, find out about Hydra's Diving Center.
Her navy. The rich maritime history of the island has left its mark on the great mansions of the captains of the Revolution, on the cobbled streets, in the old mansion that houses the School of Merchant Mariners. The Historical Archive – Hydra Museum (www.iamy.gr) with its permanent collection it will introduce you to the glorious chapters of the life of the place, while the Historical House of Lazarou Kountouriotis with its authentic furniture and works of art will put you in the mood of the era when shipping was at its peak.
