Aid climbing is a form of rock climbing that uses mechanical devices and equipment, such as aiders, for upward momentum. Aid climbing is different than free climbing, which only uses mechanical equipment for protection, but not to assist in upward momentum. "Aid climbing" sometimes involves hammering in pitons and bolts, into which aiders are clipped, but there is also "clean aid climbing" which avoids hammering, using only removable placements.

Rock climbing is a sport in which participants climb up, across, or down natural rock formations or indoor climbing walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes.
