Indoor climbing walls are artificial structures designed for rock climbing, typically found in gyms or recreational centers. They are made from various materials, such as plywood or fiberglass, and feature holds of different shapes and sizes to simulate outdoor climbing experiences. These walls can vary in height and difficulty, catering to climbers of all skill levels. Climbing walls often include safety features like padded flooring and harness systems to protect climbers. Many facilities also offer climbing classes and equipment rentals, making it accessible for beginners. Popular climbing styles include bouldering, which involves shorter walls without ropes, and top-rope climbing, where climbers are secured by a rope anchored at the top.
