I can't seem to escape all of the criticism about the Santorini crowds. This makes me wonder… are the crowds getting worse? Or are people just posting about them more on social media? I haven't been to Santorini in many years, but this is just a glimpse of what you may be faced with when visiting the island. Of course, take it with a grain of salt, and the whole island will definitely not be full of people. I do recommend visiting in May, June, and September if you want a quieter vacation.
