About Mykonos

Little Venice and the Kato Mili windmills frame the sunset in Chora, while Ornos, Platis Gialos, and Paradise draw the beach crowd on the south coast. Delos, the ancient sanctuary island, is a short boat trip and a half-day among the ruins. June through September is the season, with the meltemi wind strongest in July and August and evenings made for late dinners.
