What's great about Mykonos in September?

A Rose Tinted World Mykonos does have a few places to sightsee but is more of a chilled out beach holiday. September is coming to the end of the season, but it is still lovely and warm enough to sunbathe, and not too cool in the evenings that you need to carry a coat. I am sure it is much busier in the height of summer, but during September it was easy to get places in the bars and restaurants in Mykonos town. There are some amazing historical sites on the neighbouring island of Delos, which is well worth a boat trip to visit. Answered by A Rose Tinted World
