The Dodecanese cluster of islands are located in the easternmost region of Greece. Dodecanese are comprised by more than 150 islands of which 26 are inhabited. The most important islands are Astypalaia, Chalki, Kalymnos, Kassos, Karpathos, Kastelorizo, Kos, Leros, Nissyros, Patmos, Tilos, and Rhodes, the largest of the twelve islands.
What characterises the famous Greek coasts is their unique diversity (beaches stretching over many kilometres, small bays and coves, sandy
beaches with dunes, pebbly shores, coastal caves surrounded by steep rocks and with the characteristic dark sand of volcanic soils, coastal wetlands), and their clean and transparent waters that have made them renowned and extremely popular all over the world.
