Santorini is among the best-known Greek islands, mainly for its natural beauty. Santorini is all clear ocean, white-walled buildings and blue-domed churches. In addition, it claims to have some of the best sunsets in the world.
Santorini is an extinct volcano, a caldera where the middle has fallen into the sea creating a ring of crater islands, collectively called Santorini. Hence it has a deep-port lagoon in the middle, arid steep cliffs and dark-sand beaches. The eruption of Santorini 3,600 years ago probably caused the end of the Minoan civilization by swamping nearby Crete with a tsunami. Perhaps it was also this eruption that lost us the legendary city of Atlantis.
Santorini is 120 miles (200 km) southeast of the Greek mainland and well-served by ferries. To get around the island you can catch a bus, or hire a motorcycle and explore all the islands' hidden secrets.
