About Great Sand Beach

From Wikipedia

Great Sand (Greek: Παραλία Μεγάλη Άμμος) is a Greek beach in the island of Evia, the second biggest island of Greece. The beach is in the South part of Evia and specifically in the southwest part of a small village called Marmari, opposite of Athens, the capital of Greece. Except of the name “Great Sand” (mostly used by the locals), it is also well known as “Golden Sand”.
