XLSIOR Mykonos Festival

XLSIOR is a commercial gay party festival on Mykonos in late August: about six days of beach day-parties and club nights, sold as a festival pass. It is not a pride. The official site doesn't name the company behind it, and its photo archive goes back to 2012.

Venues change from year to year. In 2018 Proto Thema listed Elia Beach, Paradise Beach, Cavo Paradiso, Kalua and Pinky Beach, and reported sold-out passes at €320, or €600 for VIP. Check current pass prices before you go; Mykonos rooms that week are among the most expensive of the summer.

The 2026 edition ran 20 to 25 August, according to the official site. We couldn't find an attendance figure. The 2027 dates hadn't been announced when we checked.
