TREASURE HUNT IN LILLE

The treasure hunt in Lille,
neighbourhood by neighbourhood.

A treasure hunt in Lille's neighbourhoods

Organising a team building treasure hunt in Lille means transforming the Flemish city into the living backdrop for your event. Happy Unity designs routes through the city's most iconic locations: the cobbled streets and baroque houses of Vieux Lille, the Rue de la Monnaie and the Hospice Comtesse, the Grand'Place with the Vieille Bourse and the Opéra, the UNESCO-listed Belfry of the Hôtel de Ville, right up to the verdant ramparts of the Citadelle de Vauban. Each team, equipped with a tablet or their smartphone, follows a series of puzzles, photo challenges, and collaborative missions that reveal Lille from a unique perspective. The treasure hunt is just one type of our team building activities in Lille: investigations, construction challenges, culinary or creative workshops complete our catalogue.

“Everything was simply perfect. Lucile, full of sound advice, knows her trade, her services and her suppliers inside out! Her outstanding team ran everything like clockwork. In short, a seminar we will never forget and one I highly recommend. There were 70 of us over a full day with 3 highlights.”

, THE TREASURE HUNT GUIDE,

All about
the treasure hunt
in Lille.

Where can you organise a treasure hunt in Lille?+×

A corporate treasure hunt in Lille can take place in almost any neighbourhood of the city. The most popular areas are Vieux Lille and its cobbled streets around the Rue de la Monnaie, the Grand'Place with the Vieille Bourse and the Opéra, the Belfry of the Hôtel de Ville, as well as the ramparts and moats of the Citadelle de Vauban. Happy Unity has ready-to-use routes in these areas and can also design a rally in the neighbourhood of your choice, from Wazemmes to Euralille, or directly within your Lille premises.

Can you do a treasure hunt in a museum in Lille?+×

Yes. Our indoor routes take over the city's major museums: the Palais des Beaux-Arts de Lille (Rubens, Delacroix, Flemish collections), the LaM in Villeneuve-d'Ascq with its sculptures by Picasso, Léger, and Miró, the Musée La Piscine in Roubaix with its Art Deco nave, or the Louvre-Lens and its Galerie du Temps. Teams solve observation puzzles in front of the artworks, sheltered from the weather, making it an ideal format for a seminar.

How does a team building treasure hunt in Lille work?+×

A team building treasure hunt in Lille begins with an on-site briefing, then your employees are divided into teams of 4 to 8 people and receive a tablet (or use their smartphone). They then follow a Lille itinerary punctuated by puzzles, photo challenges, and observation tasks, geolocated by the Indiana app, between Vieux Lille, the Grand'Place, and Rue Faidherbe. Points accumulate before a final ranking, supervised by a Happy Unity facilitator.

How many participants can a treasure hunt in Lille accommodate?+×

A treasure hunt in Lille adapts equally well to a dozen employees or several thousand participants divided into simultaneous teams, up to 5,000 people for very large events. Thanks to the Indiana app's live dashboard, we multiply the checkpoints between Vieux Lille, the Citadelle, and the centre to avoid congestion and maintain a smooth pace.

What happens in case of rain in Lille?+×

The northern weather won't compromise your treasure hunt in Lille. Each outdoor route has an indoor Plan B: switching to the Palais des Beaux-Arts, the Musée La Piscine in Roubaix, the Vieille Bourse, or your own premises. The decision is usually made 24 hours beforehand, and the Indiana app instantly reloads the backup route without any changes for your teams.

Is a treasure hunt in Lille suitable for all employees?+×

Yes. Our treasure hunt scenarios in Lille prioritise observation, reflection, and cooperation rather than physical performance. The challenges are varied so that everyone can contribute their skills, regardless of age or role. Routes are adjusted for accessibility: the flat centre around the Grand'Place and Rue Faidherbe is easily traversed, and museum routes offer a comfortable alternative for all profiles.

Can a treasure hunt be customised for my company in Lille?+×

Absolutely. For your treasure hunt in Lille, we rewrite the scenario around your brand, your values, a product launch, or an internal message. Puzzles, challenges, visuals, and prize-giving are adapted, and the route can connect places that are important to your company, from your Lille headquarters to a seminar venue, or a symbolic monument like the Belfry or the Vieille Bourse.

Which treasure hunt format should I choose in Lille?+×

That depends on your objective. To discover a neighbourhood, opt for a geolocated urban rally in Vieux Lille or around the Grand'Place. For a seminar sheltered from the weather, prefer a museum format (Palais des Beaux-Arts, La Piscine) or the City Express. For a gourmet experience, the Rallye Gourmand connects the best addresses and Wazemmes market, while the iPad format can be deployed anywhere in the city. Our project managers will guide you based on the number of participants and available time.

How long does a treasure hunt in Lille last?+×

A treasure hunt in Lille usually lasts between 1h30 and 2h30, including briefing and final ranking. This duration adjusts to your programme: a short City Express version for a half-day seminar in the centre, or a longer format combined with lunch in Vieux Lille or a corporate party.

Can you explore the Citadelle or the surroundings of Lille?+×

Yes. The Citadelle de Vauban, its star-shaped ramparts, and verdant moats offer a highly popular outdoor setting for a treasure hunt in Lille, as does the adjoining Bois de Boulogne. Our routes also extend across the city, from the La Condition Publique industrial wasteland in Roubaix to the red bricks of its textile heritage, to help your teams discover the industrial and Flemish richness of the region.

Do you need an app or equipment to play in Lille?+×

Everything is provided. Your teams play via our Indiana application, on the tablets we provide or on their smartphones. No complex installation: the app geolocates teams in Lille, automatically triggers puzzles at the correct location, and calculates the ranking. You don't need to prepare anything technical for your treasure hunt in Lille.

Why choose Happy Unity for a treasure hunt in Lille?+×

For over 20 years, Happy Unity has been designing team building experiences and knows the Lille area perfectly. We master reconnaissance, authorisations, and logistics for the city, from Vieux Lille to the Citadelle, from the smallest group to events for several thousand people. A dedicated project manager will accompany you from conception to animation, with our in-house developed Indiana app for a seamless and 100% customisable experience.
