An exciting climbing experience without ropes but with soft mats awaits you in the bouldering hall in Lenzburg. The hall was remodelled in 2021 and offers over 120 bouldering problems on two floors, challenging both beginners and experienced climbers. A new sector is created every week so that you can always master new challenges. Access is permitted from the age of 12 and there is no special children's area. For children, we recommend Rolling Rock in Aarau, which offers additional activities such as trampolining and parkour. The family atmosphere at Kraftreaktor invites you to work out solutions together and achieve success more quickly. The Bouldertrophy takes place every year, bringing together climbers of all ages and abilities.
