Our boulder walls
An 800 m² gym dedicated to bouldering
Brussels’ first bouldering gym, Petite Île welcomes you in Anderlecht, in the heart of the Studio City Gate project. Our 800 m² space is entirely designed for climbing and sharing.
600 m² of bouldering surface await you, with 80 regularly refreshed boulders for all levels. Whether you’re a beginner or an experienced climber, you’ll find your playground.
For variety: a spray wall to explore your movement, a Güllich panel for strength work, and even a pole dance bar in our warm-up area.
After the effort, head to our cafeteria. A moment to sit down, have a drink and enjoy the view over the rooftops of Brussels.

What is bouldering?
Bouldering is climbing in its purest form. On our walls of up to 4.5 m, you climb without a rope, above thick mats that keep you safe.
You’ll see different colours on our walls: each colour represents a “problem”, a route to solve. From the easiest to the most complex, there’s something for every level. You don’t need to be an athlete to start: technique and thinking are just as important as strength.
It’s a full-body sport that builds strength, flexibility and balance. But above all, it’s an activity where everyone progresses at their own pace, alone or with others. Here, we gladly share tips and encouragement.
The best part? No need for a partner or complicated gear. Put on a pair of climbing shoes, and off you go!
