Well known cosmopolitan Greek island just opposite Ermioni. Access is easy by hydrofoils from the port of Ermioni and only takes twenty minutes. Cars are not allowed in the island and transpotation is only by donkeys or horses.
Strict laws have maintained the architectural beauty of the island. There are lots of places to do your shopping and some great walks through the narrow streets and the beautiful houses. Sea taxis run around the island if you want to see more. Normally, 3-5 hours on the islands will cover all you need to see but you can also spent the whole day if you plan to eat, swim, etc.
