Greece is essentially divided into two halves – the mainland and the islands.
This photo gallery is of the islands. (See the mainland gallery here)

The Greek Islands are a collection of over 6,000 islands and islets that belong to Greece.
Only 227 of the islands are inhabited, and only 78 of those have more than 100 inhabitants.
The large body of land in southern Greece, Peloponnese, is not a Greek island as it is connected
to the mainland by the small Isthmus of Corinth landbridge.
The largest Greek island by area is the 260km long island of Crete, located at the southern edge of the Aegean Sea.
