Who committed the crime, in which room, and with which weapon? For Halloween 2026, the Grosbois Castle offers a a Cluedo tour on Saturday, October 31 at 5 p.m. In Val-de-Marne, children aged 7 to 14, accompanied by an adult, are invited to help solve the mystery inside the historic mansion.
The concept hones in on the three questions of the deduction game: who the culprit is, where the incident took place, and what weapon was used. Whether as a team or with family, participants have just over an hour to gather clues and submit their solution. The tour also offers a chance to discover the castle via a path that diverges from its usual guided tours.
This event is part of the Domaine de Grosbois’ family-friendly programming during school holidays. Known for its horse-training center and its trotting museum, the estate also preserves a castle whose history stretches back several centuries.
Tickets must be booked through the estate's official ticket office. The price announced is €17.50 for a participating child and €15 for an accompanying adult. The 7 to 14 age range applies to this family-friendly inquiry; tickets and conditions for standard castle tours are different.
The event is held at 46 Avenue de Grosbois, in Marolles-en-Brie. You must book the Cluedo tour for October 31, which replaces the usual program for that day: the press release notes that no ordinary guided tour is planned on that date.
