Bouldering Rock Climbing is a type of rock climbing undertaken without a rope and normally limited to very short climbs so that a fall will not result in serious injury. It is typically practiced on large boulders or artificial man-made boulders. However, it may also be practiced at the base of larger rock faces, or even on buildings or public architecture.

Bouldering is the sport of climbing relatively low boulders or rock faces. Originally a form of training, bouldering became popular in its own right due to ease of participation. Climbers don't use ropes or equipment for support, instead relying on natural holds in the rock being climbed. Despite being a relatively safe sport, crash pads should be in-place prior to climbing.

Scale large rocks and boulders without the aid of ropes or support equipment.

There are no formalized rules for bouldering beyond climbers not being able to use tools or equipment for support. Due to safety concerns, some areas have restrictions on boulders that can be climbed.

The climbing of rocks, cliffs and mountains for recreational pursuits began in Europe in the early 19th century. The sport of rock climbing, a pursuit calling for distinct athletic ability, emerged from more leisurely practices at the end of the 19th century. In the 1930's and 1940's, bouldering was viewed as a form of training for climbers preparing for longer climbs. By the 1950's, bouldering had developed a loyal following and was soon accepted by the mainstream climbing community. Today, bouldering is quite popular around the world due to availability of climbing locations and the small amount of equipment needed to climb.

Climbers should avoid boulders with a height greater than seven meters, and should always use spotters and a crash pad.

Weight training can build the necessary strong arms and shoulders, while aerobic exercise and yoga can develop good flexibility and agility.
