On the edge of the Genevan countryside, near the Vallon de la Laire nature reserve, Domaine de la Mermière welcomes you for an exceptional Halloween experience!
At this family-run organic estate, the Batardon family shares their passion for vines and wine. For Halloween, discover the estate in two different ways: first, out in the fresh air of the vineyards, and then in a surprising fluorescent world!

All aboard the trailer—next stop, the vineyards!

The adventure begins on a real grape-harvesting trailer. Parents and children board together to head to the Soral vineyards and enjoy the scenery surrounding the estate.
Near a traditional vineyard hut and the Vallon de la Laire, the Batardon family will introduce you to their vineyard, organic production methods, and commitment to sustainability. But you haven’t come just to admire the view...

First candy hunt: an adventure in the vineyards

Once you arrive at the vineyard, it’s time for the first candy hunt! Parents and children set off together to find treats hidden among the vines. A true Halloween moment for the whole family, surrounded by nature.
Then, hop back on the trailer to return to the estate... A second adventure awaits!

Second hunt: kids challenge their parents—in neon style!

Back at the estate, the atmosphere changes completely: blacklight and fluorescent colors! This time, the roles are reversed...
With the help of our activity leaders, each child crafts and decorates their own glow-in-the-dark Halloween treat, then hides it within the neon world illuminated by blacklight.
Next, it’s the parents' turn! They’ll need to keep their eyes peeled to find the glow-in-the-dark treat hidden by their child.

Time to taste the estate’s wines!

After these two adventures, adults can discover the wines of Domaine de la Mermière during a guided tasting session with the Batardon family. Whether traditional, exuberant, or expressive—and some with no added sulfur—they reflect the terroir and the family's commitments.
Children can enjoy a glass of the estate’s homemade grape juice.
Charcuterie and cheese platters are also available as an option.
