Halloween 2026 in French-speaking Switzerland: 7 outings to send shivers down your spine
Autumn is settling over the shores of Lake Geneva and the surrounding countryside, and with it comes the unmissable rendezvous for thrill-seekers: Halloween. Once again this year, French-speaking Switzerland has no shortage of ideas for little and not-so-little monsters, from local legends to themed parks, spooky zoos and haunted museums. Here's our pick of the 7 events not to miss for a spine-tingling October 2026, starting with a one-of-a-kind experience in the Vaud Chablais.
1. Halloween at the Fort de Chillon Museum: deep in the heart of alpine legends
Head to Veytaux, right across from the famous Château de Chillon, for an experience that breaks with Halloween tradition. Rather than conjuring up witches and zombies imported from elsewhere, the Fort de Chillon Museum draws on Vaud folklore to bring the ancestral creatures and legends of the Alps to life, from October 10 to 31. The event was built in partnership with Damien Leuba, a Vaud-based illustrator and author of the graphic novel Topio et l'Hutzêran, inspired by the canton's ancient myths. His drawings and stories inhabit the underground galleries of this former military fortress, classified "top secret" until 2001, for an immersion that's as historical as it is unsettling.
The venue's biggest asset: all activities take place under cover, deep inside the fort, whatever the weather outside — rain, wind or cold won't change a thing. An unusual family outing, both local and rare in French-speaking Switzerland, well worth booking now as spots are expected to fill up fast.

2. Halloween at Cobalt Project in Lutry: a life-size treasure hunt
Change of pace up in the hills above Lutry, where Cobalt Project swaps its usual scenario-based paintball setting for a horror-themed treasure hunt. Across this 30,000 m² life-size playground, participants slip into a pristine white overall before setting off in search of clues hidden across the site — all while trying to dodge hunters determined to splatter them with paint. Needless to say, that white overall won't stay white for long.
The concept appeals equally to families and groups of friends looking for something more physical and interactive than a traditional haunted house. A daytime version, more accessible for younger visitors, and a night version reserved for the bravest, both run throughout October.

3. Halloween at Aigle Castle: a creature hunt in a medieval setting
Aigle Castle, a 12th-century fortress nestled among the vineyards, is transformed into a Halloween venue every year in late October. Local legend has it that its walls are haunted: children aged 6 and up set off in search of the frightening creatures hiding within, armed with logic and teamwork to solve the riddles scattered along the way.
The activity itself is free (only castle admission is charged), making it the perfect way to wrap up a Halloween outing in the Vaud Chablais, just a few kilometres from the Fort de Chillon and Montreux.

4. Beastly Halloween at Tropiquarium Servion
Who needs cardboard ghosts when you can come face to face with real crocodiles and Komodo dragons? Every autumn, Tropiquarium Servion gives its exhibits a Halloween makeover, blending wildlife discovery with seasonal thrills. Between impressive reptiles and an autumnal set-up, the venue offers an outing that's both playful and educational, especially popular with families with young children.
The venue pairs perfectly with a visit to the nearby Servion Zoo, for a full day out in the Jorat region combining nature and thrills.

5. Hallomania Festival in Geneva: ten days of city-wide festivities
No round-up of Halloween in French-speaking Switzerland would be complete without Hallomania, the Geneva festival that turns the entire city into a spooky playground for nearly ten days in late October. Vineyards, breweries, chocolate shops, the Old Town, parks and the shores of Lake Geneva all take turns hosting candy hunts, craft and magic workshops, vineyard cart rides, tastings and even night-time investigations through the historic streets.
With close to twenty activities spread across the canton, Hallomania stands out as one of the region's most comprehensive family events — a Geneva-style spectacle that contrasts with the more intimate, rural atmosphere of the Fort de Chillon.

6. Halloween Vapeur Parc in Le Bouveret: ghost trains and miniature creatures
Head to Le Bouveret for an atmosphere that's both enchanting and eerie at Swiss Vapeur Parc. From October 10 to 31, 2026, the miniature train park swaps its usual scenery for pumpkins, witches and ghosts. Giant spiders, a witch hunt and a maze await young and old every day from 10am to 6pm, with extended evening hours until 9pm on Fridays and Saturdays, as well as on October 31.
Children are strongly encouraged to come in costume to hop aboard the famous ghost train, a railway ride that promises a few chills even for the bravest — an original way to experience Halloween on a... smaller scale.

7. Halloween at Maison d'Ailleurs: science fiction joins the party
In Yverdon-les-Bains, Maison d'Ailleurs, a museum unique in Europe dedicated to science fiction and extraordinary voyages, offers its own take on the festivities with its traditional Halloween Party. A face-painting stand, costume contest and candy galore are all on the programme for this free, festive afternoon designed for families.
A great chance for young and old alike to turn into super-villains for an afternoon, before or after exploring the museum's collections dedicated to Jules Verne and the world of science fiction.

The last word
Between authentic alpine legends, life-size treasure hunts, haunted castles, spooky zoos and city-wide festivals, French-speaking Switzerland has nothing to envy the big American productions when it comes to celebrating Halloween 2026. For a genuinely local and immersive experience, the Fort de Chillon Museum remains a safe bet: a journey into the mysteries of Vaud folklore, inside a historic fortress unique in Switzerland, sheltered from the weather and just steps from the Château de Chillon and Montreux.
