Ermioni (Ερμιόνη), sometimes Hermione, is a city in the Peloponnese.
Ermioni (pop. 4,554) administratively belongs to the Prefecture of Argolis. Although it is quite popular with Athenians, especially during Easter and summer weekends, it still more peaceful than the nearby more touristed islands of Spetses and Hydra, and quite cheaper as well. Ermioni is on a very small out-cropping of the land facing the island of Hydra. Due to the fact that it faces the sea from three sides as well as the architectural style of the buildings, Ermioni gives the impression that you are actually on one of the most beautiful islands of Greece, rather than a town just 2.5 hours away from Athens.
The preferred method of travel from Athens to Ermioni, if car is not available, is by sea from the port of Piraeus. In high season several passenger-only hydrofoils and catamarans of  Hellenic Seaways]] depart the port of Piraeus daily, calling at the the islands of Poros, Hydra and Spetses, as well as the mainland ports of Ermioni and Porto Heli on the Peloponnese. Depending on the ports of call, trip duration from Piraeus to Ermioni is between 2 hours and 3 hours. Passenger tickets cost €29,5 one way.
Winter sees a major reduction in service, with only four hydrofoils daily. These are subject to cancellations when the weather turns nasty.
There are daily busses from Athens and Nafplio to the nearby town Kranidi(approximately 9km from Ermioni). The ticket from Athens costs €15,30 one way. The trip takes longer than the car trip because the buss stops to a number of towns along the way. From Kranidi there are daily busses to Ermioni, however the departure times are rarely convenient to people arriving with the buss from Athens. Another way to reach Ermioni is to hire a local taxi but be sure to ask for the price beforehand, as well as a receipt. The cheapest way is, of course, hitch-hiking.
