Kythnos

Thermal springs, empty beaches, and the magical Kolona

Overall rating: 3.5/5 · 100 km² · 1456 residents

Kythnos is the first Cycladic island you reach from the Athens Riviera, yet it remains one of the least visited. It has no airport, one main ferry link, and a population of just 1,500. The draw: 99 beaches, ancient thermal springs that have drawn bathers for 2,000 years, and an absolutely pristine double-ended beach at Kolona that looks photoshopped.
