In Ibiza, Sundays are for SINners — and SIN Sundays brings the music, mayhem, and memories. Back at O Beach for Summer 2025 this iconic pool party has reigned for 13 years with high-energy beats, Ibiza classics, wild entertainment, and epic crane shows. Happening monthly from May to September, it’s Ibiza’s fastest-selling party — so grab your spot early! and a closing party in September. See you there, SINners.
