The best time to visit Santorini, Greece is definitely October. This is when the weather is still fantastic but the crowds will be at a minimum. I truly recommend renting a car because you can freely move around from the towns of Oia, Imerovigli and Fira. Furthermore, you can explore the other side of the island that many people never see. If you can afford it, go for the 5 star resorts when booking so you can ensure that your Santorini experience is what you've always imagined it to be. The service they provide is truly amazing! #santorini #imerovigli #oia #fira #greece #romance
