A Unique Indoor Activity in Brussels Inspired by Fort Boyard

Prison Island Brussels is a brand-new concept in the heart of the city, directly inspired by the legendary TV show Fort Boyard. Spread across 32 fully immersive cells, each one hiding a unique challenge, Prison Island is one of those rare indoor activities in Brussels that genuinely works for everyone, friends, families, couples and colleagues alike.

Sometimes tactical, sometimes technical, sometimes physical: every cell pushes you in a different direction, keeping the energy high from the first minute to the last. The concept is simple but brilliantly effective: form your teams, race against the clock, conquer as many cells as possible, collect points and, most importantly, have fun.

And when you need a breather, the cosy on-site bar is the perfect spot to recharge before diving back in.

Prison Island Brussels for Groups, Friends, Families and Team Building

Prison Island is suitable for anyone aged 9 to 99, making it one of the most versatile indoor activities in Brussels for mixed groups. The 32 challenges range across physical, technical and tactical disciplines, meaning every member of your group will find their moment to shine, regardless of age or fitness level.
