Hydra is the most impressive island in the Argo-Saronic Gulf. Due to its close distance to Athens, it gets very popular as a summer weekend destination. The town is constructed on the slopes of a hill around a port and impresses visitors at first sight with the elegant stone mansions. The special thing about Hydra island is that cars and other motor vehicles are entirely prohibited in all the island, so all transport is done on foot, by boat or riding the donkey. In fact, the donkeys are very characteristic figures of Hydra Greece. Beaches on the island are actually small coves with crystal water and green surroundings. Agios Nikolaos, Bitsi, Vlichos and Kaminia are the most beautiful beaches on the island.
