Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep object. It is done recreationally, competitively, in trades that rely on it, and in emergency rescue and military operations. It is done indoors and out, on natural and manmade structures.
Climbing activities include:
Bouldering: Ascending boulders or small outcrops, often with climbing shoes and a chalk bag or bucket. Usually, instead of using a safety rope from above, injury is avoided using a crash pad and a human spotter (to direct a falling climber on to the pad. They can also give beta, or advice)
Buildering: Ascending the exterior skeletons of buildings, typically without protective equipment.
Canyoneering: Climbing along canyons for sport or recreation. Wikipedia
