From October 24 to November 1, 2026, Hallomania returns for its 4th edition with 18 events across the canton of Geneva and at Le Salève—celebrating Halloween with family, friends, or among adults!

The lineup includes candy hunts in the Old Town, parks, and vineyards, as well as creative workshops, wine tastings, chocolate making, candlelight and torchlit walks, mystery games, and much more.
New additions include a candy hunt aboard the "Train du Terroir" in Jussy, a grand lantern hunt in the Old Town, and a "Zombie Night." Teens and adults can also enjoy a brewery-based murder mystery game, a criminal investigation challenge, or a glow-in-the-dark DJ party in the vineyards.
With activities to suit all ages, tastes, and budgets, Hallomania transforms Geneva’s heritage, landscapes, and local terroir into a massive, real-life playground for Halloween.
18 events running from October 24 to November 1, 2026. Program and registration atHallomania.com
