100% Greece. Been there a few times already and would go back again and again.
All the islands in the Cyclades are awesome, all so different & beautiful- Santorini, Mykonos, Paros, Ios and Milos should definitely be on your hit list.
Unlike most of Europe, Greece is super cheap! Amazing food at little Greek taverns, the people are chilled & welcoming, you can rent quad bikes to go island adventuring-whether or not you have your license , fun to party, beautiful beaches, landscape dry but MAGESTIC!
