About Mykonos
In the heart of the Cyclades, Mykonos answers the Aegean horizon with Kato Mili, a row of 16th-century stone windmills crowning the ridge above Little Venice and its wave-washed waterfront tavernas. Along the southern coast, Paradise Beach pulses with beach clubs and daytime music, while Psarou keeps a quieter, upscale register favoured by yacht crews and the Nammos crowd. Sea temperatures sit between 23 and 25 °C from July through September, with Mykonos airport ten minutes by road.
