On Saturday, October 31st, 2026, Megalloween returns to Palexpo Geneva for an extraordinary anniversary edition.
After shaping generations of night owls, this must-attend event celebrates its 20th anniversary with an XXL version, designed to be the largest, most immersive, and most spectacular in its history.
Produced by Village du Soir
For two decades, Megalloween has transformed Halloween into a true collective experience: a night where partying meets horror, where stage sets come alive, where creatures emerge from the shadows, and where thousands of people gather to experience far more than just a simple costume party.
Megalloween is driven by a unique energy: spectacular costumes, a roaring dance floor, stagings worthy of major horror films, and an atmosphere you won't find anywhere else. At every turn, a surprise appearance, a sudden thrill, or a lifelong memory can arise.
For this 2026 edition, Festival du Soir is dreaming even bigger. For one night only, a dedicated stage will become a cursed territory entirely devoted to the universe of Halloween.
Celebrating 20 years is a big deal. But at Megalloween, we celebrate in the dark.
Prepare your costumes. Prepare your screams. Prepare to experience the most monstrous Halloween night of the year. Costumes are mandatory.
