Scaling, or climbing, is the activity of ascending steep surfaces, such as rocks or artificial walls. It can be done using various techniques and equipment, including ropes, harnesses, and climbing shoes. Climbers often aim to reach the summit of a mountain or complete a challenging route. There are different styles of climbing, including bouldering, which involves climbing shorter walls without ropes, and sport climbing, which uses fixed anchors for safety. Climbing can be both a recreational activity and a competitive sport, with events held in locations like indoor climbing gyms and natural rock formations.
