Astypalea

Astypalea is shaped like a butterfly when viewed from above, a geographic coincidence that has become the island's unofficial emblem. With roughly 1,200 permanent residents and no high-rise development, it sits in the Dodecanese chain and has been named among the world's best hidden island gems — but what distinguishes it from comparable quiet islands is not just its beaches or its Venetian Kastro above whitewashed Chora: it is the most ambitious sustainability experiment currently running on any Greek island. In 2021, Astypalea partnered with Volkswagen Group to become a living laboratory for electric mobility. The program has systematically replaced petrol vehicles with electric cars and scooters, introduced the ASTYBUS ridesharing system — with roughly 25% of the island's population participating and over 200,000 customer kilometers logged annually — and is building a 3.5-megawatt hybrid solar system targeting approximately 80% renewable energy coverage by 2026. Public approval for the initiative stands at around 80% as of 2024. For visitors, the practical effect is quieter roads, cleaner air, and the option to rent electric vehicles — a sensory contrast with mainland Greece that is immediately noticeable. The island's Chora is a genuine visual highlight: whitewashed cubic houses climb a hillside crowned by a Venetian Kastro, with blue-domed churches punctuating the slope. Kaminakia beach offers golden sand with tavernas right on the waterfront; Vatses is more dramatic with pebble beach framed by imposing rock formations; Livadi sits in a valley of citrus groves and vineyards that could be confused for Tuscany if the Aegean weren't visible on the horizon. Access is more flexible than most islands on this list. Sky Express operates flights from Athens roughly three times per week, taking about one hour, with the airport at Analipsi fifteen to twenty minutes from Chora. For those preferring the sea approach, Blue Star ferries connect from Piraeus in seven to twelve hours at fares from around €45, with approximately five weekly departures. The combination of flight access and sustainability credentials has attracted a steady stream of eco-conscious travelers and design-curious visitors who want something more thought-provoking than a standard beach holiday.
