Santorini is an island located in the Aegean Sea, southeast of mainland Greece. The distance from Athens to Santorini is about 230 kilometers (140 miles) as the plane flies.
Although it’s just one of about 30 main islands that make up the Cyclades group of Greek islands, Santorini is easily the most famous island in the group, and it’s probably the most famous island in the country of Greece!
