Every route or ‘boulder problem’ has a certain colour. The colour of the holds represents the difficulty level of the boulder problem. GRIP uses the French grading system and our boulders range from level 3A (beginners) to 8A (advanced/professional). The start and end holds are marked, but it is on you to figure out how to get from beginning to end! You will need strength, flexibility and balance. And equally important: focus and creativity.
We have approximately 200 boulders on 1000 squared meters of climbing wall. Our boulder problems are versatile and modern. We have traditional boulders with small holds that require a lot of precise footwork and finger strength; but also dynamic problems that can only be solved by jumping from one hold to another. More advanced climbers should also head to the Arena to attempt our competition style boulders. From jump start to bathang: GRIP Boulderhal is full of physical and mental challenges for beginners to advanced climbers.
Do you want to know more? Check our socials for weekly boulder updates. 
Each Monday, our professional routesetter team resets the boulders of one level/color. Each Friday, our team sets four new competition style boulder. With a different experience every week, there will always be a reason to come back for more!
For advanced climbers we have an elaborate training area with 3 spray training walls (at 20, 30 and 40 degrees) and two tension boards (at 20 and 40 degrees). You can connect to the tension boards via bluetooth and choose from various problems using your phone. The LEDs of the tension boards will change and, voilà, a new boulder has appeared!
