Kos Greece. With a coastline that unravels for over 290 kilometers, the Greek island of Kos has more than its fair share of beaches. They come in all shapes and sizes, from golden swathes backed by beach bars to hidden bays and little-known coves. The island’s good looks don’t end with its shores, either. Inland, whitewashed villages spill down the hillsides and wild flowers blanket the fields. Then there’s Mount Dikeos, whose slopes are peppered with pine forests and castles.
