Santorini is one of the most famous and beautiful islands in the world. It boasts picturesque small villages built on the edge of cliffs that soar above a sea-drowned caldera, lovely cave houses, whitewashed buildings, blue-domed churches and volcanic-sand beaches. Beyond the catchy travel headlines, there are plenty of things to see and do in Santorini as well as numerous interesting places to explore.  There are caldera-edge pathways, delicious local food, wineries producing high-quality wine made from indigenous grape varieties, an ancient city dating back 4000 years, charming backstreets, unspoiled regions and many more off-the-beaten-track attractions.
