Rock climbing is an activity whereby participants climb up, down or across natural rock formations or artificial rock walls with the aim of reaching the summit or the endpoint of a usually pre-defined route without falling. 

Rock climbing is more dangerous on descent than ascent, especially on the larger multiple pitches (class III- IV and /or multi-day grades IV-VI climbs). Professional 

Rock climbing competitions have the objectives of either completing the route in the quickest possible time or attaining the farthest point on an increasingly difficult route. Scrambling, another activity involving the scaling of hills and similar formations, is similar to rock climbing. However, rock climbing is generally differentiated by its sustained use of hands to support the climber's weight as well as to provide balance.
