ALONISSOS, GREECE

Alonissos, in the northern Sporades islands of Greece is likely not a Greek holiday destination that you’ve heard of. Mykonos and Santorini, sure, but Alonissos should be on your radar if you’re planning on doing some island hopping this summer.

It has been nominated again and listed among the world’s top 100 leading sustainable destinations, which is a distinction awarding efforts of international tourism locations for responsible and sustainable projects.

Why we love it: The island focuses its efforts to stay low impact on energy conservation. The island is small enough to cycle around, so there’s no need for a car.

Where to stay? The IKON ECO hotel, part of the Green Hotels network.
