Caccia au Trésor 2026
On Sunday 7 June 2026, Caccia au Trésor returns for its fifth edition: an urban game where teams explore Brussels through clues, riddles, challenges and places seen with fresh eyes. Taking part is free: a voluntary donation at the end of the day is welcome to support the project. This year's route looks at the intersectionality of struggles in public space and ends at Crazy Circle with prizes, an aperitif-style gathering and a DJ set.
Caccia au Trésor is not a race. It is an afternoon to walk, observe, play as a team and meet people active in the city.
The route starts at Parc Royal, near the fountain in front of the Belgian Parliament. Teams should arrive a little early to register, receive the first instructions and be ready to leave at 14:00.
Through clues, riddles and challenges, teams will discover places, associations and collectives that tell different stories about living in and reclaiming public space. The groups taking part in this edition include Casi-Uo, Urbanistas Brussels, Mediterranea, Emergency, Stripping Architecture, Walk Brussels, Heroes for Zero and Crazy Circle.
You do not need to arrive with ready-made answers. The hunt is designed to open up questions, reveal connections and look at the city from another perspective, step by step.
The arrival is planned for 18:00 at Crazy Circle in Brussels. After the hunt, there will be prizes, an aperitif-style gathering and a party with DJ set: a moment to meet again, share impressions and close the day together.

Caccia au Trésor
Giulio M.
“Through GaiaHunt we created and played incredibly engaging and learning treasure hunts in the city of Brussels, which allowed hundreds of players to know, meet and learn peculiar places and people of a city they just moved in or lived in since many years. We also wanted to raise awareness on socio-economic aspects and for charities which go much beyond the usual “sightseeing”, and the treasure hunt's features allowed to that in an entertaining way. On top of that, people made new friends and had lots of fun!”

“Did this for my birthday with six friends. We argued for twenty minutes about a riddle that turned out to be hiding in a church door handle. Best fight we've ever had.”

“I expected a tourist thing. It's actually a very good history lesson disguised as a puzzle. The bit about the Parthenon's curves genuinely changed how I see buildings now.”

Frequently asked
It's a walking route through a city, made of clues and checkpoints you solve on your phone. No guide, no tour group. You and your team go at your own pace, and the app checks your answers.
Nothing. Every public hunt is free to play. No ticket, no subscription. You only pay if you want a private hunt for a team or a gift voucher.
Yes. Every public hunt on GaiaHunt is free to play. We make money on private team events and gift vouchers, not on the core experience.
No. Hunts open in your phone browser. You tap a link, it loads, you play. Nothing to install, nothing to update.
Most hunts run 60–120 minutes. Each hunt page lists a typical time, but there's no clock. Stop for a coffee, a photo, or a long argument about a riddle.
Both work. Scavenger-type hunts are better with 3–6 people; Explorer and most City Tour hunts are great solo. Hunt pages list the recommended group size.
The hunt stays open. Most checkpoints work under cover, and there's no clock. Take shelter, come back when it clears. If the weather makes the route impossible, we'll swap you to a different hunt.
Almost all hunts are in English, French, Italian and Spanish. German, Portuguese and Dutch are coming soon.
