The best Greek islands that fly under the radar
Are you ready to discover Greece’s best-kept secrets?
The Aegean and Ionian Seas are full of wonders; from the captivating sunsets of Santorini to the Venetian charm of Corfu, there is no shortage of Greek islands that have made a name for themselves.
But what about the lesser-known Greek islands, the ones that fly under the radar and have not been spoiled by the masses of tourism?
Let's take a look at some of the most impressive Greek islands.
Kythira
Kythira, also known as Tsirigo, is where myth and reality intertwine. Nestled between the Aegean and Ionian Seas, this island feels like a place time forgot, in the best way possible. Crumbling Venetian castles, secret waterfalls, and dreamy beaches are scattered across its wild landscape.
Pirates once roamed here, Aphrodite, the goddess of love, was supposedly born here, and modern travelers come to escape the crowds. And if you really want to step off the map, take a boat to nearby Antikythera, where the world’s oldest known computer was discovered.
