Ibiza’s wildest Sundays are back — and Summer 2026 is set to be our most SINful season yet. SIN Sundays returns to O Beach for its 14th year, bringing the heat with explosive beats, iconic Ibiza anthems, outrageous entertainment, and those jaw-dropping crane shows. SIN takes over O Beach Ibiza one Sunday each month from May to September — including our unmissable opening and closing parties. Be warned… SIN SUNDAYS always sell out, so be sure to book your beds or tickets while you still can! Are you ready to SIN in 2026?
