On your approach to the Temple of Poseidon, there is a decent sandy beach at Legrena. The fine golden sand is reminiscent of the Cycladic islands, while an added bonus is the usual lack of crowds. A few miles before you arrive (from Athens), look for the sight of the small island of Patroklos. It is uninhabited today, has ancient fortress ruins, and is said to belong to a wealthy Greek family. Amenities: food and drink. Best for: solitude; swimming; walking.
