Determining what are the "best" beaches of Greece is obviously a subjective affair.
Some beaches are well organized and offer many luxuries, while others are very secluded and isolated. Some offer clear water, some perfectly soft sand, while others are framed by incredible landscape.
I believe this are the top-five best beaches of Greece
Sarakiniko (in Elafonisos Island, Peloponnese)
Simos beach is right around the corner and just as great of a beach! For such a tiny island, Elafonisos at the Southern end of Peloponnese offers three of the best beaches of Greece (Panagia beach is the third one), and just about the best looking water in the world.
Egremnoi (Lefkada)-One of the best kept secrets of Greece. Beautiful scenery, crystal clear turquoise water, and soft white coarse sand make this beach one of the best to visit. Its out-of-the-way location on the West coast of Lefkada, and the thousand make-shift concrete steps down (and then up), separate the huge crowds from this beach. Excellent by all measures.
Myrtos (Kefalonia) was voted as the best beach of Greece a few years ago, and for good reason. Fantastic water and bright-white pebbles, nested among steep cliffs on the west coast of Kefalonia.
Erimoupolis (Crete) Nested between rugged rocks and an ancient cemetery, Erimoupolis is named after the "abandoned town" of Itanos, the ruins of which you have to pass on your way to the beach. Although the beach gets too crowded during the weekends, it is a joy to visit during weekdays.
And Myrtidiotissa (Corfu) the road to Myrtidiotissa is a real hazard for any car, so travelers have to park high up the hill near the monastery of Myrtidiotissa, and then walk down about a kilometer of dirt road. The water is crystal-clear, and the strip of soft brown sand is sheltered by tall cliffs on all sides. This small beach tends to feel overcrowded during full season, but a real pleasure early in the summer.
Hotels by the beach here is one you would like-Iberostar Creta Panorama, this hotel is located near a small village named Palermo, and close to the city of Rethymon. This is a good hotels Crete choice both for families and couples. It has a large main pool with a swim-up bar and the buffet restaurant offers food that everyone will love, not to mention beer and wine taps. You will have a great time!
