4Kolona Beach, Kythnos

A natural wonder shaped like a narrow sandbar, Kolona Beach in Kythnos offers a rare double-sided paradise. The sea surrounds the golden stretch of sand on both sides, creating an illusion of two beaches merging into one.

The waters here are shallow and perfectly clear, glowing turquoise under the Aegean sun. Reaching Kolona requires a boat or a rugged drive, which keeps the crowds away and preserves its unspoiled charm. Swimming in its calm, luminous waters feels like floating between two worlds.
