Duracell Climbing Wall We put on our harnesses, seat belts, gloves, and helmets, and we are ready for the climb. Everyone who loves adventure is welcome to KidZania Duracell Climbing Wall. We will learn climbing techniques and have a lot of fun by choosing the track that suits us on our climbing wall, which has four different difficulty levels. Remember, the more you climb, the more your technique will improve and the better results you will get. We are waiting for everyone who says they climb a straight wall very well!
