The most dramatic of all the Greek islands, Santorini is best known for the cliff-top towns of Firaand Oia, which lie on the west coast, overlooking the deep, blue sea-filled caldera. Made up of typical Cycladic whitewashed cubic buildings, many of which have been converted into boutique hotels with infinity pools, both Fira and Oia are considered romantic destinations, popular for weddings and honeymoons. Things to do include sunbathing and swimming at the black volcanic sand beaches on the south and east coasts and visiting the archaeological site ofAkrotiri, an Ancient Minoan settlement buried below lava following the volcanic eruption that created the caldera, some 3,600 years ago. The island has an airport and is served by ferries and catamarans from Athens' port, Piraeus.
