The Best Islands in Greece That Aren't Santorini or Mykonos

Santorini and Mykonos are beautiful, overcrowded, and priced like they're in Monaco. Greece has over 200 inhabited islands and many of the best ones still operate at a fraction of the cost and a tenth of the tourist density. These are the islands worth your ferry tickets — places where the beaches are emptier, the tavernas are run by families, and the sunsets don't require elbowing through a crowd.

Milos is the current darling — a volcanic island in the western Cyclades with over 80 beaches, including Sarakiniko, a lunar landscape of white rock eroded into smooth formations that meets turquoise water. Kleftiko, accessible only by boat, is a sea cave complex that ranks among the most dramatic swimming spots in the Mediterranean. The island's mining history gives it a rugged personality that Santorini's postcard prettiness can't match.

Naxos is the largest Cycladic island and the most underrated. The beaches — Agios Prokopios, Plaka, Mikri Vigla — are long, sandy, and never packed. The interior is mountainous with Venetian towers, Byzantine churches, and villages where old men play backgammon in the square and nobody's selling you a sunset cruise. The local cheese (Graviera Naxou) and potatoes are DOC-protected and genuinely excellent. Ferry info at https://www.ferryhopper.com.

Folegandros is Santorini's cliffside charm without the cruise ships. The Chora (main town) sits on a cliff edge 200 meters above the sea, with whitewashed churches and a main square that feels like someone's living room. The population is under 800, hotels are small and family-run, and the bus system consists of a single vehicle. It's the Greece that existed before Instagram.

Ikaria, in the eastern Aegean, is one of the world's five Blue Zones — places where people routinely live past 100. The island runs on its own schedule (shops open when they feel like it, festivals start at midnight), the wine is locally produced and poured freely, and the thermal springs at Therma are naturally heated and free. It's the antidote to optimization culture disguised as a Greek island.

Hydra, a 90-minute ferry from Athens, bans all motorized vehicles — no cars, no scooters, no ATVs. Transport is by donkey, water taxi, or foot. The harbor, lined with 18th-century stone mansions, was painted by Picasso and has drawn artists, musicians (Leonard Cohen lived here), and writers for decades. The swimming is off rocks rather than beaches, which keeps the family-vacation crowd away.
