Mountaineering is the set of activities that involves ascending mountains.
Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas. Sport climbing and Bouldering and even Dry Tooling are also considered mountaineering by some.
Unlike most sports, mountaineering lacks widely-applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies when climbing mountains. One of the various techniques is Dry Tooling too.
