HALLOWEEN ADVENTURES ACROSS THE CANTON WITH HALLOMANIA 2026

Halloween is taking over Geneva City and the wider Canton of Geneva this autumn with Hallomania, a festival that offers a different way to celebrate the spooky season.

From 24 October to 1 November 2026, Hallomania brings together Halloween experiences across the canton. Instead of limiting the celebrations to one location, the festival turns vineyards, forests, parks, farms and other local venues into Halloween playgrounds.

There are chasse aux bonbons for children, creative workshops, haunted houses, nature adventures, train rides, wine tastings, murder mysteries and fluorescent parties. Some activities are designed for families, while others are aimed specifically at adults.

Hallomania was created in 2023 by Léman Expériences, bringing together Halloween activities that had previously been organised in different locations around Geneva. The festival has continued to grow and, in 2026, brings together 18 events across Geneva and the surrounding countryside.

Here are some of the Hallomania 2026 events to discover across the Canton:

But there is a catch: the park is also home to real, costumed mummies who are hiding among the 50 hectares of green space.
Children will have to find them, follow the clues and sometimes even run after them as they try to escape!

Halloween aboard the Train Terroir Express – JussyAll aboard for a Halloween adventure through the countryside of Jussy!
The Train Terroir Express gets a spooky makeover for the occasion, with Halloween decorations, cobwebs, mummies and the festival's friendly mascot, Hallie.
The train travels through the countryside before stopping at three different locations in the forest. At each stop, children leave the train to search for Halloween characters as part of a giant Halloween version of the “7 Families” game.
Ghosts, witches, vampires and other creatures have become separated from their families, and the young hunters have to find them. Each family member discovered can earn the children Halloween sweets before they return to the train.
A practical point for families: pushchairs are not permitted on the train, so parents travelling with babies may want to bring a baby carrier.

Then the atmosphere changes completely. Back at the domaine, the second hunt takes place under black light, creating a fluorescent Halloween world.
Before this second hunt, children aged four and over make and decorate their own glowing Halloween sweet. They then hide it in the fluorescent space – and this time, it is the parents who have to find it!

Younger children under four can participate in both family hunts and have a dedicated play area available while older children take part in the creative workshop.
