3Alonissos – Greece

The Sporades islands, less famous than the Cyclades, offer some of the quietest escapes in Greece. Alonissos stands out for its unspoiled natural beauty and the nearby marine park, a protected area home to monk seals.

Beaches like Leftos Gialos and Agios Dimitrios remain uncrowded, often empty even in summer. The island’s small villages and hiking paths provide solitude for travelers who prefer authenticity over spectacle.
