Climbing is the activity of using one`s hands and feet (or indeed any other part of the body) to ascend a steep object.

Mountaineering or mountain climbing is the sport, hobby or profession of hiking, skiing, and climbing mountains. While mountaineering began as attempts to reach the highest point of unclimbed big mountains it has branched into specializations that address different aspects of the mountain and consists of three areas: rock-craft, snow-craft and skiing, depending on whether the route chosen is over rock, snow or ice. All require experience, athletic ability, and technical knowledge to maintain safety.

Bouldering is a style of rock climbing undertaken without a rope and normally limited to very short climbs over a crash pad (called a bouldering mat) so that a fall will not result in serious injury. It is typically practiced on large natural boulders or artificial boulders in gyms and outdoor urban areas. However, it may also be practiced at the base of larger rock faces, or even on buildings or public architecture.
