Climbing room Blok has been a fixture in the Belgian climbing landscape since 1994. It was the first boulder room in the Benelux and today it is still one of the largest boulder rooms in Belgium. Climbing room Blok has a wide variety of walls, shapes and structures. The large spherical climbing structure stands out literally and figuratively. We are committed to making Klimzaal Blok a place where all climbers feel at home, whether you are a hardcore climber or someone who wants to try bouldering. We strive to build climbing routes that are both challenging and technical. Our climbing routes are built by a specialized team with the aim of motivating, inspiring and challenging you. There is also a cozy climber bar, where climbers and non-climbers can have a drink after their climbing session.
