Greece is situated in the southern end of the Balkan Peninsula between three continents, Europe, Asia and Africa. The country can be distinguished between three main geographic sections: The mainland, the peninsula of the Peloponnese that connects to the mainland through the canal of Corinth Isthmus and the islands. There are more than 2500 islands situated in the Greek waters out of which about 165 are inhabited today. The islands are scattered at the East in the sea of the Aegean and at the West in the Ionian Sea. The biggest island is Crete and the rest are organized in groups, such as the Cyclades and the Dodecanese.
