I'm heading back to Greece at the very end of August next year with some friends for almost 3 weeks and we will be focusing on Greek islands with a stop in Athens. We will probably have at least 12-16 days just for exploring the islands. It would be nice to know what some of you consider your favorite Greek island and why.
Background: This will be my third trip to Greece. Other trips have included the mainland, Peloponnese, and Athens. I have also been to Samos and Hydra, but no other islands. I'm researching islands and having hard time picking just a few as so many of them sound wonderful. We enjoy a lot of different experiences while on vacation - everything from hiking, to relaxing on the beach, seeing the historical sites, hanging out in cafes, and going out at night (either to a club or just to a late dinner). I guess I really just want to know what islands you liked and what made visiting them so enjoyable.
Thanks in advance!
